docker-login man page

docker login [Options] [SERVER]

Log in to 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 uses Docker's public registry located at https://registry-1.docker.io/ by default.  To get a username/password for Docker's public registry, create an account on Docker Hub.

docker login requires user to use sudo or be root, except when:

 1.

connecting to  a remote daemon, such as a docker-machine provisioned docker engine.

 2.

user is added to the docker group.  This will impact the security of your system; the docker group is root equivalent.  See Docker Daemon Attack Surface ⟨https://docs.docker.com/engine/security/security/#/docker-daemon-attack-surface⟩ for details.

You can log into any public or private repository for which you have credentials.  When you log in, the command stores encoded credentials in $HOME/.docker/config.json on Linux or %USERPROFILE%/.docker/config.json on Windows.
