Connect to Azure Container Registry

[bolognam]

I've been following the julia_batch_docker.ipynb example, but trying to use Azure Container Registry instead of DockerHub and I've been using the container option in the parameters.json ("_CONTAINER": "myorgregistry.azurecr.io/myimage:v0.1.0") but I continue to get an error ContainerInvalidImage with unauthorized: authentication required, visit https://aka.ms/acr/authorization for more information. This is a private org container registry.

This is the closest example that I've found to another user attempting this solution: Azure/Batch#107
And here's some docs for Python code that seems to do what I want: https://docs.microsoft.com/en-us/azure/batch/batch-docker-container-workloads#prefetch-images-from-a-private-container-registry

To me it seems like I need to be using a managed identity and to create batch pools with them. Is this something that can be supported by AzureClusterlessHPC.jl? Or is there a better solution than what I've found?

Thank you for your help!
