My question is related to the documentation in the following article:

CodePudding user response：

As described in the documentation:

Registry or Namespace: A globally unique top-level domain name for your specific registry or namespace.

DockerRepository(Image): Name of the repository where the container images are stored.

Note: the fully-qualified image name will be of the format: {registry or namespace}/{repository}:{tag}. For example, myregistry.azurecr.io/nginx:latest

The example shows the fully-qualified image name. In this sample, the Registry or Namespace should be myregistry.azurecr.io, the Repository should be nginx, and the tag should be latest.

So, we can enter them separately. Reference below screenshot:
