Azure Container Registry

How to store container images in Azure

This is an older version of the ZenML documentation. To read and view the latest version please visit this up-to-date URL.

The Azure container registry is a container registry flavor which comes built-in with ZenML and uses the Azure Container Registry to store container images.

When to use it

You should use the Azure container registry if:

• one or more components of your stack need to pull or push container images.

• you have access to Azure. If you're not using Azure, take a look at the other container registry flavors.

How to deploy it

Go here and choose a subscription, resource group, location and registry name. Then click on Review + Create and to create your container registry.

How to find the registry URI

The Azure container registry URI should have the following format:

<REGISTRY_NAME>.azurecr.io
# Examples:
zenmlregistry.azurecr.io
myregistry.azurecr.io

To figure our the URI for your registry:

• Go to the Azure portal.

• In the search bar, enter container registries and select the container registry you want to use. If you don't have any container registries yet, check out the deployment section on how to create one.

• Use the name of your registry to fill the template <REGISTRY_NAME>.azurecr.io and get your URI.

How to use it

To use the Azure container registry, we need:

• Docker installed and running.

• The Azure CLI installed and authenticated.

• The registry URI. Check out the previous section on the URI format and how to get the URI for your registry.

We can then register the container registry and use it in our active stack:

zenml container-registry register <NAME> \
    --flavor=azure \
    --uri=<REGISTRY_URI>

# Add the container registry to the active stack
zenml stack update -c <NAME>

Additionally, we'll need to login to the container registry so Docker can pull and push images:

# Fill your REGISTRY_NAME in the placeholder in the following command.
# You can find the REGISTRY_NAME as part of your registry URI: `<REGISTRY_NAME>.azurecr.io`
az acr login --name=<REGISTRY_NAME>
