• ETag: string
• Last-Modified: string

BatchError

The error from the Batch service.

string

Grants access to perform all operations on the Job containing the Task.

string

The ID of the application to deploy.
When creating a pool, the package's application ID must be fully qualified (/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Batch/batchAccounts/{accountName}/applications/{applicationName}).

string

The version of the application to deploy. If omitted, the default version is deployed.
If this is omitted on a Pool, and no default version is specified for this application, the request fails with the error code InvalidApplicationPackageReferences and HTTP status code 409. If this is omitted on a Task, and no default version is specified for this application, the Task fails with a pre-processing error.

AccessScope[]

The Batch resources to which the token grants access.
The authentication token grants access to a limited set of Batch service operations. Currently the only supported value for the access property is 'job', which grants access to all operations related to the Job which contains the Task.

boolean

Whether OS image rollback feature should be disabled.

boolean

Indicates whether OS upgrades should automatically be applied to scale set instances in a rolling fashion when a newer version of the OS image becomes available.

If this is set to true for Windows based pools, WindowsConfiguration.enableAutomaticUpdates cannot be set to true.

boolean

Defer OS upgrades on the TVMs if they are running tasks.

boolean

Indicates whether rolling upgrade policy should be used during Auto OS Upgrade. Auto OS Upgrade will fallback to the default policy if no policy is defined on the VMSS.

string

A prefix to be added to the unique identifier when a Pool is automatically created.
The Batch service assigns each auto Pool a unique identifier on creation. To distinguish between Pools created for different purposes, you can specify this element to add a prefix to the ID that is assigned. The prefix can be up to 20 characters long.

boolean

Whether to keep an auto Pool alive after its lifetime expires.
If false, the Batch service deletes the Pool once its lifetime (as determined by the poolLifetimeOption setting) expires; that is, when the Job or Job Schedule completes. If true, the Batch service does not delete the Pool automatically. It is up to the user to delete auto Pools created with this option.

PoolSpecification

The Pool specification for the auto Pool.

PoolLifetimeOption

The minimum lifetime of created auto Pools, and how multiple Jobs on a schedule are assigned to Pools.

string

Specifies that the Task runs as the common auto user Account which is created on every Compute Node in a Pool.

string

Specifies that the service should create a new user for the Task.

ElevationLevel

The elevation level of the auto user.
The default value is nonAdmin.

AutoUserScope

The scope for the auto user
The default value is pool. If the pool is running Windows a value of Task should be specified if stricter isolation between tasks is required. For example, if the task mutates the registry in a way which could impact other tasks, or if certificates have been specified on the pool which should not be accessible by normal tasks but should be accessible by StartTasks.

CertificateStoreLocation

The location of the Certificate store on the Compute Node into which to install the Certificate.
The default value is currentuser. This property is applicable only for Pools configured with Windows Compute Nodes. For Linux Compute Nodes, the Certificates are stored in a directory inside the Task working directory and an environment variable AZ_BATCH_CERTIFICATES_DIR is supplied to the Task to query for this location. For Certificates with visibility of 'remoteUser', a 'certs' directory is created in the user's home directory (e.g., /home/{user-name}/certs) and Certificates are placed in that directory.

EnvironmentSetting[]

The list of common environment variable settings. These environment variables are set for all Tasks in the Job (including the Job Manager, Job Preparation and Job Release Tasks).
Individual Tasks can override an environment setting specified here by specifying the same setting name with a different value.

JobConstraints

The execution constraints for the Job.

string

The creation time of the Job.

string

The display name for the Job.

string

The ETag of the Job.
This is an opaque string. You can use it to detect whether the Job has changed between requests. In particular, you can be pass the ETag when updating a Job to specify that your changes should take effect only if nobody else has modified the Job in the meantime.

JobExecutionInformation

The execution information for the Job.

string

A string that uniquely identifies the Job within the Account.
The ID is case-preserving and case-insensitive (that is, you may not have two IDs within an Account that differ only by case).

JobManagerTask

Details of a Job Manager Task to be launched when the Job is started.
The Job Manager Task is automatically started when the Job is created. The Batch service tries to schedule the Job Manager Task before any other Tasks in the Job. When shrinking a Pool, the Batch service tries to preserve Nodes where Job Manager Tasks are running for as long as possible (that is, Compute Nodes running 'normal' Tasks are removed before Compute Nodes running Job Manager Tasks). When a Job Manager Task fails and needs to be restarted, the system tries to schedule it at the highest priority. If there are no idle Compute Nodes available, the system may terminate one of the running Tasks in the Pool and return it to the queue in order to make room for the Job Manager Task to restart. Note that a Job Manager Task in one Job does not have priority over Tasks in other Jobs. Across Jobs, only Job level priorities are observed. For example, if a Job Manager in a priority 0 Job needs to be restarted, it will not displace Tasks of a priority 1 Job. Batch will retry Tasks when a recovery operation is triggered on a Node. Examples of recovery operations include (but are not limited to) when an unhealthy Node is rebooted or a Compute Node disappeared due to host failure. Retries due to recovery operations are independent of and are not counted against the maxTaskRetryCount. Even if the maxTaskRetryCount is 0, an internal retry due to a recovery operation may occur. Because of this, all Tasks should be idempotent. This means Tasks need to tolerate being interrupted and restarted without causing any corruption or duplicate data. The best practice for long running Tasks is to use some form of checkpointing.

JobPreparationTask

The Job Preparation Task.
The Job Preparation Task is a special Task run on each Compute Node before any other Task of the Job.

JobReleaseTask

The Job Release Task.
The Job Release Task is a special Task run at the end of the Job on each Compute Node that has run any other Task of the Job.

string

The last modified time of the Job.
This is the last time at which the Job level data, such as the Job state or priority, changed. It does not factor in task-level changes such as adding new Tasks or Tasks changing state.

integer

The maximum number of tasks that can be executed in parallel for the job.
The value of maxParallelTasks must be -1 or greater than 0 if specified. If not specified, the default value is -1, which means there's no limit to the number of tasks that can be run at once. You can update a job's maxParallelTasks after it has been created using the update job API.

MetadataItem[]

A list of name-value pairs associated with the Job as metadata.
The Batch service does not assign any meaning to metadata; it is solely for the use of user code.

JobNetworkConfiguration

The network configuration for the Job.

OnAllTasksComplete

The action the Batch service should take when all Tasks in the Job are in the completed state.
The default is noaction.

OnTaskFailure

The action the Batch service should take when any Task in the Job fails.
A Task is considered to have failed if has a failureInfo. A failureInfo is set if the Task completes with a non-zero exit code after exhausting its retry count, or if there was an error starting the Task, for example due to a resource file download error. The default is noaction.

PoolInformation

The Pool settings associated with the Job.

JobState

The previous state of the Job.
This property is not set if the Job is in its initial Active state.

string

The time at which the Job entered its previous state.
This property is not set if the Job is in its initial Active state.

integer

The priority of the Job.
Priority values can range from -1000 to 1000, with -1000 being the lowest priority and 1000 being the highest priority. The default value is 0.

JobState

The current state of the Job.

string

The time at which the Job entered its current state.

JobStatistics

Resource usage statistics for the entire lifetime of the Job.
This property is populated only if the CloudJob was retrieved with an expand clause including the 'stats' attribute; otherwise it is null. The statistics may not be immediately available. The Batch service performs periodic roll-up of statistics. The typical delay is about 30 minutes.

string

The URL of the Job.

boolean

Whether Tasks in the Job can define dependencies on each other. The default is false.

string

As many Tasks as possible (taskSlotsPerNode) should be assigned to each Compute Node in the Pool before any Tasks are assigned to the next Compute Node in the Pool.

string

Tasks should be assigned evenly across all Compute Nodes in the Pool.

string

The ARM resource id of the user assigned identity.

string[]

The collection of container Image names.
This is the full Image reference, as would be specified to "docker pull". An Image will be sourced from the default Docker registry unless the Image is fully qualified with an alternative registry.

ContainerRegistry[]

Additional private registries from which containers can be pulled.
If any Images must be downloaded from a private registry which requires credentials, then those credentials must be provided here.

ContainerType

The container technology to be used.

boolean

Mount this source path as read-only mode or not. Default value is false (read/write mode).
For Linux, if you mount this path as a read/write mode, this does not mean that all users in container have the read/write access for the path, it depends on the access in host VM. If this path is mounted read-only, all users within the container will not be able to modify the path.

For example, 18.04-LTS or 2019-Datacenter.

string

The version of the Azure Virtual Machines Marketplace Image.
A value of 'latest' can be specified to select the latest version of an Image. If omitted, the default is 'latest'.

string

The ARM resource identifier of the Azure Compute Gallery Image. Compute Nodes in the Pool will be created using this Image Id. This is of the form /subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Compute/galleries/{galleryName}/images/{imageDefinitionName}/versions/{VersionId} or /subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Compute/galleries/{galleryName}/images/{imageDefinitionName} for always defaulting to the latest image version.
This property is mutually exclusive with other ImageReference properties. The Azure Compute Gallery Image must have replicas in the same region and must be in the same subscription as the Azure Batch account. If the image version is not specified in the imageId, the latest version will be used. For information about the firewall settings for the Batch Compute Node agent to communicate with the Batch service see https://docs.microsoft.com/azure/batch/nodes-and-pools#virtual-network-vnet-and-firewall-configuration.

string

Use TCP for the endpoint.

string

Use UDP for the endpoint.

integer

The port number on the Compute Node.
This must be unique within a Batch Pool. Acceptable values are between 1 and 65535 except for 29876 and 29877 as these are reserved. If any reserved values are provided the request fails with HTTP status code 400.

integer

The last port number in the range of external ports that will be used to provide inbound access to the backendPort on individual Compute Nodes.
Acceptable values range between 1 and 65534 except ports from 50000 to 55000 which are reserved by the Batch service. All ranges within a Pool must be distinct and cannot overlap. Each range must contain at least 40 ports. If any reserved or overlapping values are provided the request fails with HTTP status code 400.

integer

The first port number in the range of external ports that will be used to provide inbound access to the backendPort on individual Compute Nodes.
Acceptable values range between 1 and 65534 except ports from 50000 to 55000 which are reserved. All ranges within a Pool must be distinct and cannot overlap. Each range must contain at least 40 ports. If any reserved or overlapping values are provided the request fails with HTTP status code 400.

string

The name of the endpoint.
The name must be unique within a Batch Pool, can contain letters, numbers, underscores, periods, and hyphens. Names must start with a letter or number, must end with a letter, number, or underscore, and cannot exceed 77 characters. If any invalid values are provided the request fails with HTTP status code 400.

NetworkSecurityGroupRule[]

A list of network security group rules that will be applied to the endpoint.
The maximum number of rules that can be specified across all the endpoints on a Batch Pool is 25. If no network security group rules are specified, a default rule will be created to allow inbound access to the specified backendPort. If the maximum number of network security group rules is exceeded the request fails with HTTP status code 400.

InboundEndpointProtocol

The protocol of the endpoint.

string

A public IP will be created and managed by Batch. There may be multiple public IPs depending on the size of the Pool.

string

No public IP Address will be created.

string

Public IPs are provided by the user and will be used to provision the Compute Nodes.

integer

The maximum number of times each Task may be retried. The Batch service retries a Task if its exit code is nonzero.
Note that this value specifically controls the number of retries. The Batch service will try each Task once, and may then retry up to this limit. For example, if the maximum retry count is 3, Batch tries a Task up to 4 times (one initial try and 3 retries). If the maximum retry count is 0, the Batch service does not retry Tasks. If the maximum retry count is -1, the Batch service retries Tasks without limit. The default value is 0 (no retries).

string

The maximum elapsed time that the Job may run, measured from the time the Job is created.
If the Job does not complete within the time limit, the Batch service terminates it and any Tasks that are still running. In this case, the termination reason will be MaxWallClockTimeExpiry. If this property is not specified, there is no time limit on how long the Job may run.

string

The completion time of the Job.
This property is set only if the Job is in the completed state.

string

The ID of the Pool to which this Job is assigned.
This element contains the actual Pool where the Job is assigned. When you get Job details from the service, they also contain a poolInfo element, which contains the Pool configuration data from when the Job was added or updated. That poolInfo element may also contain a poolId element. If it does, the two IDs are the same. If it does not, it means the Job ran on an auto Pool, and this property contains the ID of that auto Pool.

JobSchedulingError

Details of any error encountered by the service in starting the Job.
This property is not set if there was no error starting the Job.

string

The start time of the Job.
This is the time at which the Job was created.

string

A string describing the reason the Job ended.
This property is set only if the Job is in the completed state. If the Batch service terminates the Job, it sets the reason as follows: JMComplete - the Job Manager Task completed, and killJobOnCompletion was set to true. MaxWallClockTimeExpiry - the Job reached its maxWallClockTime constraint. TerminateJobSchedule - the Job ran as part of a schedule, and the schedule terminated. AllTasksComplete - the Job's onAllTasksComplete attribute is set to terminatejob, and all Tasks in the Job are complete. TaskFailed - the Job's onTaskFailure attribute is set to performExitOptionsJobAction, and a Task in the Job failed with an exit condition that specified a jobAction of terminatejob. Any other string is a user-defined reason specified in a call to the 'Terminate a Job' operation.

boolean

Whether the Job Manager Task may run on a Spot/Low-priority Compute Node.
The default value is true.

ApplicationPackageReference[]

A list of Application Packages that the Batch service will deploy to the Compute Node before running the command line.
Application Packages are downloaded and deployed to a shared directory, not the Task working directory. Therefore, if a referenced Application Package is already on the Compute Node, and is up to date, then it is not re-downloaded; the existing copy on the Compute Node is used. If a referenced Application Package cannot be installed, for example because the package has been deleted or because download failed, the Task fails.

AuthenticationTokenSettings

The settings for an authentication token that the Task can use to perform Batch service operations.
If this property is set, the Batch service provides the Task with an authentication token which can be used to authenticate Batch service operations without requiring an Account access key. The token is provided via the AZ_BATCH_AUTHENTICATION_TOKEN environment variable. The operations that the Task can carry out using the token depend on the settings. For example, a Task can request Job permissions in order to add other Tasks to the Job, or check the status of the Job or of other Tasks under the Job.

string

The command line of the Job Manager Task.
The command line does not run under a shell, and therefore cannot take advantage of shell features such as environment variable expansion. If you want to take advantage of such features, you should invoke the shell in the command line, for example using "cmd /c MyCommand" in Windows or "/bin/sh -c MyCommand" in Linux. If the command line refers to file paths, it should use a relative path (relative to the Task working directory), or use the Batch provided environment variable (https://docs.microsoft.com/azure/batch/batch-compute-node-environment-variables).

TaskConstraints

Constraints that apply to the Job Manager Task.

TaskContainerSettings

The settings for the container under which the Job Manager Task runs.
If the Pool that will run this Task has containerConfiguration set, this must be set as well. If the Pool that will run this Task doesn't have containerConfiguration set, this must not be set. When this is specified, all directories recursively below the AZ_BATCH_NODE_ROOT_DIR (the root of Azure Batch directories on the node) are mapped into the container, all Task environment variables are mapped into the container, and the Task command line is executed in the container. Files produced in the container outside of AZ_BATCH_NODE_ROOT_DIR might not be reflected to the host disk, meaning that Batch file APIs will not be able to access those files.

string

The display name of the Job Manager Task.
It need not be unique and can contain any Unicode characters up to a maximum length of 1024.

EnvironmentSetting[]

A list of environment variable settings for the Job Manager Task.

string

A string that uniquely identifies the Job Manager Task within the Job.
The ID can contain any combination of alphanumeric characters including hyphens and underscores and cannot contain more than 64 characters.

boolean

Whether completion of the Job Manager Task signifies completion of the entire Job.
If true, when the Job Manager Task completes, the Batch service marks the Job as complete. If any Tasks are still running at this time (other than Job Release), those Tasks are terminated. If false, the completion of the Job Manager Task does not affect the Job status. In this case, you should either use the onAllTasksComplete attribute to terminate the Job, or have a client or user terminate the Job explicitly. An example of this is if the Job Manager creates a set of Tasks but then takes no further role in their execution. The default value is true. If you are using the onAllTasksComplete and onTaskFailure attributes to control Job lifetime, and using the Job Manager Task only to create the Tasks for the Job (not to monitor progress), then it is important to set killJobOnCompletion to false.

OutputFile[]

A list of files that the Batch service will upload from the Compute Node after running the command line.
For multi-instance Tasks, the files will only be uploaded from the Compute Node on which the primary Task is executed.

integer

The number of scheduling slots that the Task requires to run.
The default is 1. A Task can only be scheduled to run on a compute node if the node has enough free scheduling slots available. For multi-instance Tasks, this property is not supported and must not be specified.

ResourceFile[]

A list of files that the Batch service will download to the Compute Node before running the command line.
Files listed under this element are located in the Task's working directory. There is a maximum size for the list of resource files. When the max size is exceeded, the request will fail and the response error code will be RequestEntityTooLarge. If this occurs, the collection of ResourceFiles must be reduced in size. This can be achieved using .zip files, Application Packages, or Docker Containers.

boolean

Whether the Job Manager Task requires exclusive use of the Compute Node where it runs.
If true, no other Tasks will run on the same Node for as long as the Job Manager is running. If false, other Tasks can run simultaneously with the Job Manager on a Compute Node. The Job Manager Task counts normally against the Compute Node's concurrent Task limit, so this is only relevant if the Compute Node allows multiple concurrent Tasks. The default value is true.

UserIdentity

The user identity under which the Job Manager Task runs.
If omitted, the Task runs as a non-administrative user unique to the Task.

boolean

Whether to withdraw Compute Nodes from the virtual network to DNC when the job is terminated or deleted.
If true, nodes will remain joined to the virtual network to DNC. If false, nodes will automatically withdraw when the job ends. Defaults to false.

string

The ARM resource identifier of the virtual network subnet which Compute Nodes running Tasks from the Job will join for the duration of the Task.
The virtual network must be in the same region and subscription as the Azure Batch Account. The specified subnet should have enough free IP addresses to accommodate the number of Compute Nodes which will run Tasks from the Job. This can be up to the number of Compute Nodes in the Pool. The 'MicrosoftAzureBatch' service principal must have the 'Classic Virtual Machine Contributor' Role-Based Access Control (RBAC) role for the specified VNet so that Azure Batch service can schedule Tasks on the Nodes. This can be verified by checking if the specified VNet has any associated Network Security Groups (NSG). If communication to the Nodes in the specified subnet is denied by an NSG, then the Batch service will set the state of the Compute Nodes to unusable. This is of the form /subscriptions/{subscription}/resourceGroups/{group}/providers/{provider}/virtualNetworks/{network}/subnets/{subnet}. If the specified VNet has any associated Network Security Groups (NSG), then a few reserved system ports must be enabled for inbound communication from the Azure Batch service. For Pools created with a Virtual Machine configuration, enable ports 29876 and 29877, as well as port 22 for Linux and port 3389 for Windows. Port 443 is also required to be open for outbound connections for communications to Azure Storage. For more details see: https://docs.microsoft.com/azure/batch/batch-api-basics#virtual-network-vnet-and-firewall-configuration

string

The command line of the Job Preparation Task.
The command line does not run under a shell, and therefore cannot take advantage of shell features such as environment variable expansion. If you want to take advantage of such features, you should invoke the shell in the command line, for example using "cmd /c MyCommand" in Windows or "/bin/sh -c MyCommand" in Linux. If the command line refers to file paths, it should use a relative path (relative to the Task working directory), or use the Batch provided environment variable (https://docs.microsoft.com/azure/batch/batch-compute-node-environment-variables).

TaskConstraints

Constraints that apply to the Job Preparation Task.

TaskContainerSettings

The settings for the container under which the Job Preparation Task runs.
When this is specified, all directories recursively below the AZ_BATCH_NODE_ROOT_DIR (the root of Azure Batch directories on the node) are mapped into the container, all Task environment variables are mapped into the container, and the Task command line is executed in the container. Files produced in the container outside of AZ_BATCH_NODE_ROOT_DIR might not be reflected to the host disk, meaning that Batch file APIs will not be able to access those files.

EnvironmentSetting[]

A list of environment variable settings for the Job Preparation Task.

string

A string that uniquely identifies the Job Preparation Task within the Job.
The ID can contain any combination of alphanumeric characters including hyphens and underscores and cannot contain more than 64 characters. If you do not specify this property, the Batch service assigns a default value of 'jobpreparation'. No other Task in the Job can have the same ID as the Job Preparation Task. If you try to submit a Task with the same id, the Batch service rejects the request with error code TaskIdSameAsJobPreparationTask; if you are calling the REST API directly, the HTTP status code is 409 (Conflict).

boolean

Whether the Batch service should rerun the Job Preparation Task after a Compute Node reboots.
The Job Preparation Task is always rerun if a Compute Node is reimaged, or if the Job Preparation Task did not complete (e.g. because the reboot occurred while the Task was running). Therefore, you should always write a Job Preparation Task to be idempotent and to behave correctly if run multiple times. The default value is true.

ResourceFile[]

A list of files that the Batch service will download to the Compute Node before running the command line.
Files listed under this element are located in the Task's working directory. There is a maximum size for the list of resource files. When the max size is exceeded, the request will fail and the response error code will be RequestEntityTooLarge. If this occurs, the collection of ResourceFiles must be reduced in size. This can be achieved using .zip files, Application Packages, or Docker Containers.

UserIdentity

The user identity under which the Job Preparation Task runs.
If omitted, the Task runs as a non-administrative user unique to the Task on Windows Compute Nodes, or a non-administrative user unique to the Pool on Linux Compute Nodes.

boolean

Whether the Batch service should wait for the Job Preparation Task to complete successfully before scheduling any other Tasks of the Job on the Compute Node. A Job Preparation Task has completed successfully if it exits with exit code 0.
If true and the Job Preparation Task fails on a Node, the Batch service retries the Job Preparation Task up to its maximum retry count (as specified in the constraints element). If the Task has still not completed successfully after all retries, then the Batch service will not schedule Tasks of the Job to the Node. The Node remains active and eligible to run Tasks of other Jobs. If false, the Batch service will not wait for the Job Preparation Task to complete. In this case, other Tasks of the Job can start executing on the Compute Node while the Job Preparation Task is still running; and even if the Job Preparation Task fails, new Tasks will continue to be scheduled on the Compute Node. The default value is true.

string

The command line of the Job Release Task.
The command line does not run under a shell, and therefore cannot take advantage of shell features such as environment variable expansion. If you want to take advantage of such features, you should invoke the shell in the command line, for example using "cmd /c MyCommand" in Windows or "/bin/sh -c MyCommand" in Linux. If the command line refers to file paths, it should use a relative path (relative to the Task working directory), or use the Batch provided environment variable (https://docs.microsoft.com/azure/batch/batch-compute-node-environment-variables).

TaskContainerSettings

The settings for the container under which the Job Release Task runs.
When this is specified, all directories recursively below the AZ_BATCH_NODE_ROOT_DIR (the root of Azure Batch directories on the node) are mapped into the container, all Task environment variables are mapped into the container, and the Task command line is executed in the container. Files produced in the container outside of AZ_BATCH_NODE_ROOT_DIR might not be reflected to the host disk, meaning that Batch file APIs will not be able to access those files.

EnvironmentSetting[]

A list of environment variable settings for the Job Release Task.

string

A string that uniquely identifies the Job Release Task within the Job.
The ID can contain any combination of alphanumeric characters including hyphens and underscores and cannot contain more than 64 characters. If you do not specify this property, the Batch service assigns a default value of 'jobrelease'. No other Task in the Job can have the same ID as the Job Release Task. If you try to submit a Task with the same id, the Batch service rejects the request with error code TaskIdSameAsJobReleaseTask; if you are calling the REST API directly, the HTTP status code is 409 (Conflict).

string

The maximum elapsed time that the Job Release Task may run on a given Compute Node, measured from the time the Task starts. If the Task does not complete within the time limit, the Batch service terminates it. The default value is 15 minutes. You may not specify a timeout longer than 15 minutes. If you do, the Batch service rejects it with an error; if you are calling the REST API directly, the HTTP status code is 400 (Bad Request).

ResourceFile[]

A list of files that the Batch service will download to the Compute Node before running the command line. There is a maximum size for the list of resource files. When the max size is exceeded, the request will fail and the response error code will be RequestEntityTooLarge. If this occurs, the collection of ResourceFiles must be reduced in size. This can be achieved using .zip files, Application Packages, or Docker Containers.
Files listed under this element are located in the Task's working directory.

string

The minimum time to retain the Task directory for the Job Release Task on the Compute Node. After this time, the Batch service may delete the Task directory and all its contents.
The default is 7 days, i.e. the Task directory will be retained for 7 days unless the Compute Node is removed or the Job is deleted.

UserIdentity

The user identity under which the Job Release Task runs.
If omitted, the Task runs as a non-administrative user unique to the Task.

ErrorCategory

The Job is available to have Tasks scheduled.

string

All Tasks have terminated, and the system will not accept any more Tasks or any further changes to the Job.

string

A user has requested that the Job be deleted, but the delete operation is still in progress (for example, because the system is still terminating running Tasks).

string

A user has disabled the Job. No Tasks are running, and no new Tasks will be scheduled.

string

A user has requested that the Job be disabled, but the disable operation is still in progress (for example, waiting for Tasks to terminate).

string

A user has requested that the Job be enabled, but the enable operation is still in progress.

string

The Job is about to complete, either because a Job Manager Task has completed or because the user has terminated the Job, but the terminate operation is still in progress (for example, because Job Release Tasks are running).

string

string

The URL of the statistics.

string

The total user mode CPU time (summed across all cores and all Compute Nodes) consumed by all Tasks in the Job.

string

The total wait time of all Tasks in the Job.
The wait time for a Task is defined as the elapsed time between the creation of the Task and the start of Task execution. (If the Task is retried due to failures, the wait time is the time to the most recent Task execution.) This value is only reported in the Account lifetime statistics; it is not included in the Job statistics.

string

The total wall clock time of all Tasks in the Job.
The wall clock time is the elapsed time from when the Task started running on a Compute Node to when it finished (or to the last time the statistics were updated, if the Task had not finished by then). If a Task was retried, this includes the wall clock time of all the Task retries.

number

The total amount of data in GiB written to disk by all Tasks in the Job.

integer

The total number of disk write operations made by all Tasks in the Job.

integer

The group ID for the user Account.
The uid and gid properties must be specified together or not at all. If not specified the underlying operating system picks the gid.

string

The SSH private key for the user Account.
The private key must not be password protected. The private key is used to automatically configure asymmetric-key based authentication for SSH between Compute Nodes in a Linux Pool when the Pool's enableInterNodeCommunication property is true (it is ignored if enableInterNodeCommunication is false). It does this by placing the key pair into the user's .ssh directory. If not specified, password-less SSH is not configured between Compute Nodes (no modification of the user's .ssh directory is done).

integer

The user ID of the user Account.
The uid and gid properties must be specified together or not at all. If not specified the underlying operating system picks the uid.

boolean

Whether this pool should enable accelerated networking.
Accelerated networking enables single root I/O virtualization (SR-IOV) to a VM, which may lead to improved networking performance. For more details, see: https://video2.skills-academy.com/azure/virtual-network/accelerated-networking-overview.

PoolEndpointConfiguration

The configuration for endpoints on Compute Nodes in the Batch Pool.

PublicIPAddressConfiguration

The Public IPAddress configuration for Compute Nodes in the Batch Pool.
The public IP Address configuration of the networking configuration of a Pool.

string

The ARM resource identifier of the virtual network subnet which the Compute Nodes of the Pool will join. This is of the form /subscriptions/{subscription}/resourceGroups/{group}/providers/{provider}/virtualNetworks/{network}/subnets/{subnet}.
The virtual network must be in the same region and subscription as the Azure Batch Account. The specified subnet should have enough free IP addresses to accommodate the number of Compute Nodes in the Pool. If the subnet doesn't have enough free IP addresses, the Pool will partially allocate Nodes and a resize error will occur. The 'MicrosoftAzureBatch' service principal must have the 'Classic Virtual Machine Contributor' Role-Based Access Control (RBAC) role for the specified VNet. The specified subnet must allow communication from the Azure Batch service to be able to schedule Tasks on the Nodes. This can be verified by checking if the specified VNet has any associated Network Security Groups (NSG). If communication to the Nodes in the specified subnet is denied by an NSG, then the Batch service will set the state of the Compute Nodes to unusable. Only ARM virtual networks ('Microsoft.Network/virtualNetworks') are supported. If the specified VNet has any associated Network Security Groups (NSG), then a few reserved system ports must be enabled for inbound communication, including ports 29876 and 29877. Also enable outbound connections to Azure Storage on port 443. For more details see: https://docs.microsoft.com/azure/batch/nodes-and-pools#virtual-network-vnet-and-firewall-configuration

NetworkSecurityGroupRuleAccess

The action that should be taken for a specified IP address, subnet range or tag.

integer

The priority for this rule.
Priorities within a Pool must be unique and are evaluated in order of priority. The lower the number the higher the priority. For example, rules could be specified with order numbers of 150, 250, and 350. The rule with the order number of 150 takes precedence over the rule that has an order of 250. Allowed priorities are 150 to 4096. If any reserved or duplicate values are provided the request fails with HTTP status code 400.

string

The source address prefix or tag to match for the rule.
Valid values are a single IP address (i.e. 10.10.10.10), IP subnet (i.e. 192.168.1.0/24), default tag, or * (for all addresses). If any other values are provided the request fails with HTTP status code 400.

string[]

The source port ranges to match for the rule.
Valid values are '' (for all ports 0 - 65535), a specific port (i.e. 22), or a port range (i.e. 100-200). The ports must be in the range of 0 to 65535. Each entry in this collection must not overlap any other entry (either a range or an individual port). If any other values are provided the request fails with HTTP status code 400. The default value is ''.

string

Allow access.

string

Deny access.

string

Additional command line options to pass to the mount command.
These are 'net use' options in Windows and 'mount' options in Linux.

string

The relative path on the compute node where the file system will be mounted
All file systems are mounted relative to the Batch mounts directory, accessible via the AZ_BATCH_NODE_MOUNTS_DIR environment variable.

string

The URI of the file system to mount.

string

Nodes using the classic communication mode require inbound TCP communication on ports 29876 and 29877 from the "BatchNodeManagement.{region}" service tag and outbound TCP communication on port 443 to the "Storage.region" and "BatchNodeManagement.{region}" service tags.

string

The node communication mode is automatically set by the Batch service.

string

Nodes using the simplified communication mode require outbound TCP communication on port 443 to the "BatchNodeManagement.{region}" service tag. No open inbound ports are required.

NodePlacementPolicyType

Node placement Policy type on Batch Pools.
Allocation policy used by Batch Service to provision the nodes. If not specified, Batch will use the regional policy.

string

All nodes in the pool will be allocated in the same region.

string

Nodes in the pool will be spread across different availability zones with best effort balancing.

string

Do nothing. The Job remains active unless terminated or disabled by some other means.

string

Terminate the Job. The Job's terminateReason is set to 'AllTasksComplete'.

string

Do nothing. The Job remains active unless terminated or disabled by some other means.

string

Take the action associated with the Task exit condition in the Task's exitConditions collection. (This may still result in no action being taken, if that is what the Task specifies.)

CachingType

Specifies the caching requirements. Possible values are: None, ReadOnly, ReadWrite. The default values are: None for Standard storage. ReadOnly for Premium storage.
The default value for caching is none. For information about the caching options see: https://blogs.msdn.microsoft.com/windowsazurestorage/2012/06/27/exploring-windows-azure-drives-disks-and-images/.

integer

The initial disk size in GB when creating new OS disk.

DiffDiskSettings

Specifies the ephemeral Disk Settings for the operating system disk used by the compute node (VM).

ManagedDisk

The managed disk parameters.

boolean

Specifies whether writeAccelerator should be enabled or disabled on the disk.

OutputFileDestination

The destination for the output file(s).

string

A pattern indicating which file(s) to upload.
Both relative and absolute paths are supported. Relative paths are relative to the Task working directory. The following wildcards are supported: * matches 0 or more characters (for example pattern abc* would match abc or abcdef), ** matches any directory, ? matches any single character, [abc] matches one character in the brackets, and [a-c] matches one character in the range. Brackets can include a negation to match any character not specified (for example [!abc] matches any character but a, b, or c). If a file name starts with "." it is ignored by default but may be matched by specifying it explicitly (for example .gif will not match .a.gif, but ..gif will). A simple example: ***.txt matches any file that does not start in '.' and ends with .txt in the Task working directory or any subdirectory. If the filename contains a wildcard character it can be escaped using brackets (for example abc[] would match a file named abc). Note that both \ and / are treated as directory separators on Windows, but only / is on Linux. Environment variables (%var% on Windows or $var on Linux) are expanded prior to the pattern being applied.

OutputFileUploadOptions

Additional options for the upload operation, including under what conditions to perform the upload.

string

The URL of the container within Azure Blob Storage to which to upload the file(s).
If not using a managed identity, the URL must include a Shared Access Signature (SAS) granting write permissions to the container.

ComputeNodeIdentityReference

The reference to the user assigned identity to use to access Azure Blob Storage specified by containerUrl
The identity must have write access to the Azure Blob Storage container

string

The destination blob or virtual directory within the Azure Storage container.
If filePattern refers to a specific file (i.e. contains no wildcards), then path is the name of the blob to which to upload that file. If filePattern contains one or more wildcards (and therefore may match multiple files), then path is the name of the blob virtual directory (which is prepended to each blob name) to which to upload the file(s). If omitted, file(s) are uploaded to the root of the container with a blob name matching their file name.

HttpHeader[]

A list of name-value pairs for headers to be used in uploading output files
These headers will be specified when uploading files to Azure Storage. Official document on allowed headers when uploading blobs: https://docs.microsoft.com/rest/api/storageservices/put-blob#request-headers-all-blob-types

OutputFileBlobContainerDestination

A location in Azure blob storage to which files are uploaded.

string

Upload the file(s) after the Task process exits, no matter what the exit code was.

string

Upload the file(s) only after the Task process exits with a nonzero exit code.

string

Upload the file(s) only after the Task process exits with an exit code of 0.

OutputFileUploadCondition

The conditions under which the Task output file or set of files should be uploaded.
The default is taskcompletion.

InboundNATPool[]

A list of inbound NAT Pools that can be used to address specific ports on an individual Compute Node externally.
The maximum number of inbound NAT Pools per Batch Pool is 5. If the maximum number of inbound NAT Pools is exceeded the request fails with HTTP status code 400. This cannot be specified if the IPAddressProvisioningType is NoPublicIPAddresses.

AutoPoolSpecification

Characteristics for a temporary 'auto pool'. The Batch service will create this auto Pool when the Job is submitted.
If auto Pool creation fails, the Batch service moves the Job to a completed state, and the Pool creation error is set in the Job's scheduling error property. The Batch service manages the lifetime (both creation and, unless keepAlive is specified, deletion) of the auto Pool. Any user actions that affect the lifetime of the auto Pool while the Job is active will result in unexpected behavior. You must specify either the Pool ID or the auto Pool specification, but not both.

string

The ID of an existing Pool. All the Tasks of the Job will run on the specified Pool.
You must ensure that the Pool referenced by this property exists. If the Pool does not exist at the time the Batch service tries to schedule a Job, no Tasks for the Job will run until you create a Pool with that id. Note that the Batch service will not reject the Job request; it will simply not run Tasks until the Pool exists. You must specify either the Pool ID or the auto Pool specification, but not both.

string

The Pool exists for the lifetime of the Job to which it is dedicated. The Batch service creates the Pool when it creates the Job. If the 'job' option is applied to a Job Schedule, the Batch service creates a new auto Pool for every Job created on the schedule.

string

The Pool exists for the lifetime of the Job Schedule. The Batch Service creates the Pool when it creates the first Job on the schedule. You may apply this option only to Job Schedules, not to Jobs.

ApplicationPackageReference[]

The list of Packages to be installed on each Compute Node in the Pool.
When creating a pool, the package's application ID must be fully qualified (/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Batch/batchAccounts/{accountName}/applications/{applicationName}). Changes to Package references affect all new Nodes joining the Pool, but do not affect Compute Nodes that are already in the Pool until they are rebooted or reimaged. There is a maximum of 10 Package references on any given Pool.

string

The time interval at which to automatically adjust the Pool size according to the autoscale formula.
The default value is 15 minutes. The minimum and maximum value are 5 minutes and 168 hours respectively. If you specify a value less than 5 minutes or greater than 168 hours, the Batch service rejects the request with an invalid property value error; if you are calling the REST API directly, the HTTP status code is 400 (Bad Request).

string

The formula for the desired number of Compute Nodes in the Pool.
This property must not be specified if enableAutoScale is set to false. It is required if enableAutoScale is set to true. The formula is checked for validity before the Pool is created. If the formula is not valid, the Batch service rejects the request with detailed error information.

CertificateReference[]

A list of Certificates to be installed on each Compute Node in the Pool.
For Windows Nodes, the Batch service installs the Certificates to the specified Certificate store and location. For Linux Compute Nodes, the Certificates are stored in a directory inside the Task working directory and an environment variable AZ_BATCH_CERTIFICATES_DIR is supplied to the Task to query for this location. For Certificates with visibility of 'remoteUser', a 'certs' directory is created in the user's home directory (e.g., /home/{user-name}/certs) and Certificates are placed in that directory.

Warning: This property is deprecated and will be removed after February, 2024. Please use the Azure KeyVault Extension instead.

string

The display name for the Pool.
The display name need not be unique and can contain any Unicode characters up to a maximum length of 1024.

boolean

Whether the Pool size should automatically adjust over time.
If false, at least one of targetDedicatedNodes and targetLowPriorityNodes must be specified. If true, the autoScaleFormula element is required. The Pool automatically resizes according to the formula. The default value is false.

boolean

Whether the Pool permits direct communication between Compute Nodes.
Enabling inter-node communication limits the maximum size of the Pool due to deployment restrictions on the Compute Nodes of the Pool. This may result in the Pool not reaching its desired size. The default value is false.

MetadataItem[]

A list of name-value pairs associated with the Pool as metadata.
The Batch service does not assign any meaning to metadata; it is solely for the use of user code.

MountConfiguration[]

A list of file systems to mount on each node in the pool.
This supports Azure Files, NFS, CIFS/SMB, and Blobfuse.

NetworkConfiguration

The network configuration for the Pool.
The network configuration for a Pool.

string

The timeout for allocation of Compute Nodes to the Pool.
This timeout applies only to manual scaling; it has no effect when enableAutoScale is set to true. The default value is 15 minutes. The minimum value is 5 minutes. If you specify a value less than 5 minutes, the Batch service rejects the request with an error; if you are calling the REST API directly, the HTTP status code is 400 (Bad Request).

object

The user-specified tags associated with the pool.
The user-defined tags to be associated with the Azure Batch Pool. When specified, these tags are propagated to the backing Azure resources associated with the pool. This property can only be specified when the Batch account was created with the poolAllocationMode property set to 'UserSubscription'.

StartTask

A Task to run on each Compute Node as it joins the Pool. The Task runs when the Compute Node is added to the Pool or when the Compute Node is restarted.
Batch will retry Tasks when a recovery operation is triggered on a Node. Examples of recovery operations include (but are not limited to) when an unhealthy Node is rebooted or a Compute Node disappeared due to host failure. Retries due to recovery operations are independent of and are not counted against the maxTaskRetryCount. Even if the maxTaskRetryCount is 0, an internal retry due to a recovery operation may occur. Because of this, all Tasks should be idempotent. This means Tasks need to tolerate being interrupted and restarted without causing any corruption or duplicate data. The best practice for long running Tasks is to use some form of checkpointing. In some cases the StartTask may be re-run even though the Compute Node was not rebooted. Special care should be taken to avoid StartTasks which create breakaway process or install/launch services from the StartTask working directory, as this will block Batch from being able to re-run the StartTask.

integer

The desired number of dedicated Compute Nodes in the Pool.
This property must not be specified if enableAutoScale is set to true. If enableAutoScale is set to false, then you must set either targetDedicatedNodes, targetLowPriorityNodes, or both.

integer

The desired number of Spot/Low-priority Compute Nodes in the Pool.
This property must not be specified if enableAutoScale is set to true. If enableAutoScale is set to false, then you must set either targetDedicatedNodes, targetLowPriorityNodes, or both.

NodeCommunicationMode

The desired node communication mode for the pool.
If omitted, the default value is Default.

TaskSchedulingPolicy

How Tasks are distributed across Compute Nodes in a Pool.
If not specified, the default is spread.

integer

The number of task slots that can be used to run concurrent tasks on a single compute node in the pool.
The default value is 1. The maximum value is the smaller of 4 times the number of cores of the vmSize of the pool or 256.

The upgrade policy for the pool.
Describes an upgrade policy - automatic, manual, or rolling.

UserAccount[]

The list of user Accounts to be created on each Compute Node in the Pool.

VirtualMachineConfiguration

The virtual machine configuration for the Pool.
This property must be specified.

string

For information about available sizes of virtual machines in Pools, see Choose a VM size for Compute Nodes in an Azure Batch Pool (https://docs.microsoft.com/azure/batch/batch-pool-vm-sizes).

string[]

The list of public IPs which the Batch service will use when provisioning Compute Nodes.
The number of IPs specified here limits the maximum size of the Pool - 100 dedicated nodes or 100 Spot/Low-priority nodes can be allocated for each public IP. For example, a pool needing 250 dedicated VMs would need at least 3 public IPs specified. Each element of this collection is of the form: /subscriptions/{subscription}/resourceGroups/{group}/providers/Microsoft.Network/publicIPAddresses/{ip}.

IPAddressProvisioningType

The provisioning type for Public IP Addresses for the Pool.
The default value is BatchManaged.

string

The storage container name in the auto storage Account.
The autoStorageContainerName, storageContainerUrl and httpUrl properties are mutually exclusive and one of them must be specified.

string

The blob prefix to use when downloading blobs from an Azure Storage container. Only the blobs whose names begin with the specified prefix will be downloaded.
The property is valid only when autoStorageContainerName or storageContainerUrl is used. This prefix can be a partial filename or a subdirectory. If a prefix is not specified, all the files in the container will be downloaded.

string

The file permission mode attribute in octal format.
This property applies only to files being downloaded to Linux Compute Nodes. It will be ignored if it is specified for a resourceFile which will be downloaded to a Windows Compute Node. If this property is not specified for a Linux Compute Node, then a default value of 0770 is applied to the file.

string

The location on the Compute Node to which to download the file(s), relative to the Task's working directory.
If the httpUrl property is specified, the filePath is required and describes the path which the file will be downloaded to, including the filename. Otherwise, if the autoStorageContainerName or storageContainerUrl property is specified, filePath is optional and is the directory to download the files to. In the case where filePath is used as a directory, any directory structure already associated with the input data will be retained in full and appended to the specified filePath directory. The specified relative path cannot break out of the Task's working directory (for example by using '..').

string

The URL of the file to download.
The autoStorageContainerName, storageContainerUrl and httpUrl properties are mutually exclusive and one of them must be specified. If the URL points to Azure Blob Storage, it must be readable from compute nodes. There are three ways to get such a URL for a blob in Azure storage: include a Shared Access Signature (SAS) granting read permissions on the blob, use a managed identity with read permission, or set the ACL for the blob or its container to allow public access.

ComputeNodeIdentityReference

The reference to the user assigned identity to use to access Azure Blob Storage specified by storageContainerUrl or httpUrl
The reference to a user assigned identity associated with the Batch pool which a compute node will use.

string

The URL of the blob container within Azure Blob Storage.
The autoStorageContainerName, storageContainerUrl and httpUrl properties are mutually exclusive and one of them must be specified. This URL must be readable and listable from compute nodes. There are three ways to get such a URL for a container in Azure storage: include a Shared Access Signature (SAS) granting read and list permissions on the container, use a managed identity with read and list permissions, or set the ACL for the container to allow public access.

boolean

Allow VMSS to ignore AZ boundaries when constructing upgrade batches. Take into consideration the Update Domain and maxBatchInstancePercent to determine the batch size. This field is able to be set to true or false only when using NodePlacementConfiguration as Zonal.

integer

The maximum percent of total virtual machine instances that will be upgraded simultaneously by the rolling upgrade in one batch. As this is a maximum, unhealthy instances in previous or future batches can cause the percentage of instances in a batch to decrease to ensure higher reliability. The value of this field should be between 5 and 100, inclusive. If both maxBatchInstancePercent and maxUnhealthyInstancePercent are assigned with value, the value of maxBatchInstancePercent should not be more than maxUnhealthyInstancePercent.

integer

The maximum percentage of the total virtual machine instances in the scale set that can be simultaneously unhealthy, either as a result of being upgraded, or by being found in an unhealthy state by the virtual machine health checks before the rolling upgrade aborts. This constraint will be checked prior to starting any batch. The value of this field should be between 5 and 100, inclusive. If both maxBatchInstancePercent and maxUnhealthyInstancePercent are assigned with value, the value of maxBatchInstancePercent should not be more than maxUnhealthyInstancePercent.

integer

The maximum percentage of upgraded virtual machine instances that can be found to be in an unhealthy state. This check will happen after each batch is upgraded. If this percentage is ever exceeded, the rolling update aborts. The value of this field should be between 0 and 100, inclusive.

string

string

The service artifact reference id of ServiceArtifactReference
The service artifact reference id in the form of /subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Compute/galleries/{galleryName}/serviceArtifacts/{serviceArtifactName}/vmArtifactsProfiles/{vmArtifactsProfilesName}

string

The command line of the StartTask.
The command line does not run under a shell, and therefore cannot take advantage of shell features such as environment variable expansion. If you want to take advantage of such features, you should invoke the shell in the command line, for example using "cmd /c MyCommand" in Windows or "/bin/sh -c MyCommand" in Linux. If the command line refers to file paths, it should use a relative path (relative to the Task working directory), or use the Batch provided environment variable (https://docs.microsoft.com/azure/batch/batch-compute-node-environment-variables).

TaskContainerSettings

The settings for the container under which the StartTask runs.
When this is specified, all directories recursively below the AZ_BATCH_NODE_ROOT_DIR (the root of Azure Batch directories on the node) are mapped into the container, all Task environment variables are mapped into the container, and the Task command line is executed in the container. Files produced in the container outside of AZ_BATCH_NODE_ROOT_DIR might not be reflected to the host disk, meaning that Batch file APIs will not be able to access those files.

EnvironmentSetting[]

A list of environment variable settings for the StartTask.

integer

The maximum number of times the Task may be retried.
The Batch service retries a Task if its exit code is nonzero. Note that this value specifically controls the number of retries. The Batch service will try the Task once, and may then retry up to this limit. For example, if the maximum retry count is 3, Batch tries the Task up to 4 times (one initial try and 3 retries). If the maximum retry count is 0, the Batch service does not retry the Task. If the maximum retry count is -1, the Batch service retries the Task without limit, however this is not recommended for a start task or any task. The default value is 0 (no retries).

ResourceFile[]

A list of files that the Batch service will download to the Compute Node before running the command line. There is a maximum size for the list of resource files. When the max size is exceeded, the request will fail and the response error code will be RequestEntityTooLarge. If this occurs, the collection of ResourceFiles must be reduced in size. This can be achieved using .zip files, Application Packages, or Docker Containers.
Files listed under this element are located in the Task's working directory.

UserIdentity

The user identity under which the StartTask runs.
If omitted, the Task runs as a non-administrative user unique to the Task.

boolean

Whether the Batch service should wait for the StartTask to complete successfully (that is, to exit with exit code 0) before scheduling any Tasks on the Compute Node.
If true and the StartTask fails on a Node, the Batch service retries the StartTask up to its maximum retry count (maxTaskRetryCount). If the Task has still not completed successfully after all retries, then the Batch service marks the Node unusable, and will not schedule Tasks to it. This condition can be detected via the Compute Node state and failure info details. If false, the Batch service will not wait for the StartTask to complete. In this case, other Tasks can start executing on the Compute Node while the StartTask is still running; and even if the StartTask fails, new Tasks will continue to be scheduled on the Compute Node. The default is true.

string

The data disk / OS disk should use premium locally redundant storage.

string

The data disk / OS disk should use standard locally redundant storage.

string

The data disk / OS disk should use standard SSD locally redundant storage.

integer

The maximum number of times the Task may be retried. The Batch service retries a Task if its exit code is nonzero.
Note that this value specifically controls the number of retries for the Task executable due to a nonzero exit code. The Batch service will try the Task once, and may then retry up to this limit. For example, if the maximum retry count is 3, Batch tries the Task up to 4 times (one initial try and 3 retries). If the maximum retry count is 0, the Batch service does not retry the Task after the first attempt. If the maximum retry count is -1, the Batch service retries the Task without limit, however this is not recommended for a start task or any task. The default value is 0 (no retries).

string

The maximum elapsed time that the Task may run, measured from the time the Task starts. If the Task does not complete within the time limit, the Batch service terminates it.
If this is not specified, there is no time limit on how long the Task may run.

string

The minimum time to retain the Task directory on the Compute Node where it ran, from the time it completes execution. After this time, the Batch service may delete the Task directory and all its contents.
The default is 7 days, i.e. the Task directory will be retained for 7 days unless the Compute Node is removed or the Job is deleted.

ContainerHostBatchBindMountEntry[]

The paths you want to mounted to container task.
If this array is null or be not present, container task will mount entire temporary disk drive in windows (or AZ_BATCH_NODE_ROOT_DIR in Linux). It won't' mount any data paths into container if this array is set as empty.

string

Additional options to the container create command.
These additional options are supplied as arguments to the "docker create" command, in addition to those controlled by the Batch Service.

string

The Image to use to create the container in which the Task will run.
This is the full Image reference, as would be specified to "docker pull". If no tag is provided as part of the Image name, the tag ":latest" is used as a default.

This property must be specified if the Compute Nodes in the Pool need to have empty data disks attached to them. This cannot be updated. Each Compute Node gets its own disk (the disk is not a file share). Existing disks cannot be attached, each attached disk is empty. When the Compute Node is removed from the Pool, the disk and all data associated with it is also deleted. The disk is not formatted after being attached, it must be formatted before use - for more information see https://docs.microsoft.com/azure/virtual-machines/linux/classic/attach-disk#initialize-a-new-data-disk-in-linux and https://docs.microsoft.com/azure/virtual-machines/windows/attach-disk-ps#add-an-empty-data-disk-to-a-virtual-machine.
