Which command tags an existing image under a new repository/name and tag in Podman?

• A. sudo podman tag mysql-custom devops/mysql:snapshot
• B. sudo podman rmi mysql-custom
• C. oc tag mysql-custom devops/mysql:snapshot
• D. docker tag mysql-custom devops/mysql:snapshot

Answer: (A)

Tagging an existing image with a new repository/name and tag in Podman is done with the podman tag command. The correct command uses the current image name as the source (mysql-custom) and creates a new reference (devops/mysql:snapshot) as the target, effectively giving the same image another alias under a different repository and tag. This does not modify the image itself, it just adds another way to refer to it. Other options perform different actions or use different tools: removing an image (rmi) deletes it; OpenShift’s oc tag works with image streams in OpenShift rather than Podman; and docker tag uses the Docker CLI, not Podman (you would use podman tag instead in Podman workflows).
