What is the docker registry server specified when creating the quayio secret?

Explanation:
When you create a quayio secret, you’re configuring credentials for pulling images from Quay’s registry. The registry server field is the host name of the registry you’re authenticating against. For Quay, that host is quay.io, which is the exact domain used in the Docker config to reach Quay’s registry. Using docker.io would point to Docker Hub, quay.net isn’t the standard Quay domain, and registry.example.com is just a placeholder. So the correct registry server to specify is quay.io.
