docker-login (1)

NAME

docker-login - Log in to a Docker registry.

SYNOPSIS

docker login [--help] [-p|--password[=PASSWORD]] [-u|--username[=USERNAME]] [SERVER]

DESCRIPTION

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 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 [la]docs.docker.com/articles/security/#docker-daemon-attack-surface[ra] 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.

Note: When running sudo docker login credentials are saved in /root/.docker/config.json.
