Previously, gated preview containers were hosted on the containerpreview.azurecr.io repository. As of September 22, 2020, these containers are hosted on the Microsoft Container Registry. Downloading them doesn't require you to use the docker login command. You can run a gated preview container if your Azure resource was created with the approved Azure subscription ID. You won't be able to run the container if your Azure subscription hasn't been approved after completion of the request form.
