      "Version: v1.114.0",
      "--docker (required): Selects Docker configuration; registers glab as a Docker credential helper. Writes to `$DOCKER_CONFIG`, or `~/.docker` if unset.",
      "--registry <registry_host> (required): Registry to authenticate against. For Docker, provide a bare hostname; use only a registry backed by Artifact Registry.",
      "--duration: Sets exchanged token lifetime for other package managers; ignored for Docker.",
      "--hostname: GitLab hostname to request the token from; defaults to the configured GitLab instance.",
      "Prerequisite: Run `glab auth login` first if no credential is stored for the GitLab host. The Docker helper reads credentials from the configuration file and ignores `GITLAB_TOKEN`.",
      "Docs conflict: Current GitLab Artifact Registry Docker documentation says the GitLab CLI version must be 1.115.0 or later, newer than the card’s v1.114.0. That page does not establish this prerequisite for v1.114.0: https://docs.gitlab.com/artifact-registry/formats/docker/"
