Container registry authentication

Container registry authentication is the security process used to verify the identity of a user or client attempting to interact with a container registry, such as Quay.io or Docker Hub.^[400-devops-03-containerization-query-io.md]

Authentication Workflow

The standard procedure for accessing a secured registry involves the command-line interface of the container tool (e.g., Docker).^[400-devops-03-containerization-query-io.md]

  1. Login: The user initiates a session using the docker login command followed by the registry's domain.^[400-devops-03-containerization-query-io.md]
  2. Credential Submission: The system prompts for the username, password, and email address to validate the user's identity.^[400-devops-03-containerization-query-io.md]
  3. Authenticated Operations: Once verified, the user can perform privileged actions, such as pushing images to the registry.^[400-devops-03-containerization-query-io.md]

Example
