When working with Docker, managing authentication and sessions with Docker registries is crucial. One important command for this purpose is docker logout, which allows users to securely terminate their session with Docker registries.

Logging out from Docker Registries:

docker logout revokes the authentication token or credentials stored locally for accessing Docker registries. This command is useful in scenarios where you want to switch between different Docker Hub accounts or revoke access to a specific registry.

Here are a few examples of how to use docker logout:

1. Logout from the default Docker registry:

   docker logout

   Output:

   Removing login credentials for https://index.docker.io/v1/

   Verification: To verify if logout was successful, attempt to pull or push an image that requires authentication. If Docker prompts for credentials, logout was successful.

2. Logout from a specific registry (e.g., private registry hosted at myregistry.example.com):

   docker logout myregistry.example.com

   Output:

   Removing login credentials for https://myregistry.example.com

   Verification: Verify by attempting to authenticate against the registry again. If prompted for credentials, logout was successful.

3. Force logout from all Docker registries:

   docker logout --all

   Output:

   Removing all login credentials from your Docker configuration

   Verification: Check Docker configuration files to ensure all registry credentials are removed.
