How would you log into quay.io using Podman?

• A. sudo podman login -u <user> quay.io
• B. podman login -u <user> quay.io
• C. docker login quay.io -u <user>
• D. sudo login podman quay.io -u <user>

Answer: (A)

Log into a container registry by authenticating with Podman against the registry host you’ll be using. For quay.io, you specify the registry host in the login command and provide your username with the -u option. The command you’d run is the one that includes elevated privileges in environments where root access is required to reach the container credential store or to perform the login operation, followed by the registry host. In practice, you’ll be prompted for your password after you run this, or you can pass the password securely via -p or --password-stdin for scripting. After a successful login, Podman stores the credentials in its credential store so subsequent pulls or pushes to quay.io don’t require re-entering the password.
