container registry authentication

Hello @
kan jag, Welcome to microsoft Q&A,Thankyou for posting query here. It seems like you are having trouble logging into your Azure container registry. There could be several reasons for this error. Let's try to troubleshoot this issue step by step. First, make sure that you have the correct login server name of the registry. When using docker login, provide the full login server name of the registry, such as myregistry.azurecr.io. Ensure that you use only lowercase letters. docker login myregistry.azurecr.io If you are still unable to log in, confirm that the Docker CLI client and daemon (Docker Engine) are running in your environment. You need Docker client version 18.03 or later. Most Azure Container Registry authentication flows require a local Docker installation so you can authenticate with your registry for operations such as pushing and pulling images. If you have confirmed that Docker is installed and running, then check if the registry credentials are valid. You can confirm this by running the following command: az acr login --name <registry-name> If you are still unable to log in, then check if the credentials are authorized for push, pull, or Azure Resource Manager operations. You can confirm this by checking the role assignments for the registry. Make sure that you have the correct role assignments and access privileges. If you have confirmed that the credentials are authorized and you are still unable to log in, then check if the credentials are expired. You can confirm this by checking the expiration date of the credentials. If none of the above solutions work, then you can run the az acr check-health command to get more information about the health of the registry environment and optionally access to a target registry. For example, diagnose Docker configuration errors or Azure Active Directory login problems.
