docker-login - Register or log in to a Docker registry.
docker login [-e|--email[=EMAIL]] [--help] [-p|--password[=PASSWORD]]
Register or log in to a Docker Registry located on the specified SERVER. You can specify

2. user is added to the docker group. This will impact the security of your system; the
docker group is root equivalent. See

or %USERPROFILE%/.docker/config.json on Windows.
Note: When running sudo docker login credentials are saved in
