Log out of a Docker Registry located on the specified `SERVER`. You can specify a URL or a `hostname` for the `SERVER` value. If you do not specify a `SERVER`, the command attempts to log you out of Docker's public registry located at `https://registry-1.docker.io/` by default. # EXAMPLES ## Log out from a registry on your localhost # docker logout localhost:8080 # See also **docker-login(1)** to log in to a Docker registry server.
