[<CommonParameters>] Description
The New-AzBatchTask cmdlet creates an Azure Batch task under the job specified by the JobId parameter or the Job parameter.
Examples
Example 1: Create a Batch task
New-AzBatchTask -JobId "Job-000001" -Id "Task23" -CommandLine "cmd /c dir /s" -BatchContext $ContextThis command creates a task that has the ID Task23 under the job that has the ID Job-000001. The task runs the specified command. Use the Get-AzBatchAccountKey cmdlet to assign a context to the $Context variable.
Example 2: Create a Batch task
$autoUser = New-Object Microsoft.Azure.Commands.Batch.Models.PSAutoUserSpecification -ArgumentList @("Task", "Admin")
$userIdentity = New-Object Microsoft.Azure.Commands.Batch.Models.PSUserIdentity $autoUser
Get-AzBatchJob -Id "Job-000001" -BatchContext $Context | New-AzBatchTask -Id "Task26" -CommandLine "cmd /c echo hello > newFile.txt" -UserIdentity $userIdentity -BatchContext $ContextThis command gets the Batch job that has the ID Job-000001 by using the Get-AzBatchJob cmdlet. The command passes that job to the current cmdlet by using the pipeline operator. The command creates a task that has the ID Task26 under that job. The task runs the specified command by using elevated permissions.
Example 3: Add a collection of tasks to the specified job by using the pipeline
$Context = Get-AzBatchAccountKey -AccountName "ContosoBatchAccount"
$Task01 = New-Object Microsoft.Azure.Commands.Batch.Models.PSCloudTask("Task23", "cmd /c dir /s")
$Task02 = New-Object Microsoft.Azure.Commands.Batch.Models.PSCloudTask("Task24", "cmd /c dir /s")
Get-AzBatchJob -Id "Job-000001" -BatchContext $Context | New-AzBatchTask -Tasks @($Task01, $Task02) -BatchContext $ContextThe first command creates an object reference to the account keys for the batch account named ContosoBatchAccount by using Get-AzBatchAccountKey. The command stores this object reference in the $Context variable. The next two commands create PSCloudTask objects by using the New-Object cmdlet. The commands store the tasks in the $Task01 and $Task02 variables. The final command gets the Batch job that has the ID Job-000001 by using Get-AzBatchJob. Then the command passes that job to the current cmdlet by using the pipeline operator. The command adds a collection of tasks under that job. The command uses the context stored in $Context.
Example 4: Add a collection of tasks to the specified job
$Context = Get-AzBatchAccountKey -AccountName "ContosoBatchAccount"
$Task01 = New-Object Microsoft.Azure.Commands.Batch.Models.PSCloudTask("Task23", "cmd /c dir /s")
$Task02 = New-Object Microsoft.Azure.Commands.Batch.Models.PSCloudTask("Task24", "cmd /c dir /s")
New-AzBatchTask -JobId "Job-000001" -Tasks @($Task01, $Task02) -BatchContext $ContextThe first command creates an object reference to the account keys for the batch account named ContosoBatchAccount by using Get-AzBatchAccountKey. The command stores this object reference in the $Context variable. The next two commands create PSCloudTask objects by using the New-Object cmdlet. The commands store the tasks in the $Task01 and $Task02 variables. The final command adds the tasks stored in $Task01 and $Task02 under the job that has the ID Job-000001.
Example 5: Add a task with output files
New-AzBatchTask -JobId "Job-000001" -Id "Task23" -CommandLine "cmd /c dir /s" -BatchContext $Context
$blobContainerDestination = New-Object Microsoft.Azure.Commands.Batch.Models.PSOutputFileBlobContainerDestination "https://myaccount.blob.core.windows.net/sascontainer?sv=2015-04-05&st=2015-04-29T22%3A18%3A26Z&se=2015-04-30T02%3A23%3A26Z&sr=b&sp=rw&spr=https&sig=Z%2FRHIX5Xcg0Mq2rqI3OlWTjEg2tYkboXr1P9ZUXDtkk%3D"
$destination = New-Object Microsoft.Azure.Commands.Batch.Models.PSOutputFileDestination $blobContainerDestination
$uploadOptions = New-Object Microsoft.Azure.Commands.Batch.Models.PSOutputFileUploadOptions "TaskSuccess"
$outputFile = New-Object Microsoft.Azure.Commands.Batch.Models.PSOutputFile "*.txt", $blobContainerDestination, $uploadOptions
New-AzBatchTask -JobId "Job-000001" -Id "Task23" -CommandLine "cmd /c dir /s" -OutputFile $outputFile -BatchContext $ContextExample 6: Add a task with authentication token settings
$authSettings = New-Object Microsoft.Azure.Commands.Batch.Models.PSAuthenticationTokenSettings
$authSettings.Access = "Job"
New-AzBatchTask -JobId "Job-000001" -Id "Task23" -CommandLine "cmd /c dir /s" -AuthenticationTokenSettings $authSettings -BatchContext $ContextExample 7: Add a task which runs in a container
$Context = Get-AzBatchAccountKey -AccountName "ContosoBatchAccount"
New-AzBatchTask -JobId "Job-000001" -Id "Task23" -CommandLine "cmd /c dir /s" -ContainerSettings (New-Object Microsoft.Azure.Commands.Batch.Models.PSTaskContainerSettings "containerImageName") -BatchContext $ContextParameters
-AffinityInformation
Specifies a locality hint that the Batch service uses to select a node on which to run the task.
| Type: | PSAffinityInformation |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ApplicationPackageReferences
| Type: | PSApplicationPackageReference[] |
| Aliases: | ApplicationPackageReference |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-AuthenticationTokenSettings
The settings for an authentication token that the task can use to perform Batch service operations. If this 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.

| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-BatchContext
Specifies the BatchAccountContext instance that this cmdlet uses to interact with the Batch service. If you use the Get-AzBatchAccount cmdlet to get your BatchAccountContext, then Microsoft Entra authentication will be used when interacting with the Batch service. To use shared key authentication instead, use the Get-AzBatchAccountKey cmdlet to get a BatchAccountContext object with its access keys populated. When using shared key authentication, the primary access key is used by default. To change the key to use, set the BatchAccountContext.KeyInUse property.

-ContainerSettings
The settings for the container under which the task runs. If the pool that will run this task has containerConfiguration set, this must be set as well.
