------------------------------------------

There is one way to connect to Azure Container Registry using Airflow.

1. Use `Individual login with Azure AD
   <https://docs.microsoft.com/en-us/azure/container-registry/container-registry-authentication#individual-login-with-azure-ad>`_
   i.e. add specific credentials to the Airflow connection.

Default Connection IDs
----------------------

All hooks and operators related to Microsoft Azure Container Registry use ``azure_container_registry_default`` by default.

Configuring the Connection
--------------------------

Login
    Specify the Image Registry Username used for the initial connection.

Password
    Specify the Image Registry Password used for the initial connection.

Host
    Specify the Image Registry Server used for the initial connection.

When specifying the connection in environment variable you should specify
it using URI syntax.

Note that all components of the URI should be URL-encoded.

For example:

    export AIRFLOW_CONN_AZURE_CONTAINER_REGISTRY_DEFAULT='azure-container-registry://username:password@myregistry.com?tenant=tenant+id&account_name=store+name'
