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 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 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.

OPTIONS

--help Print usage statement

-p, --password="" Password

-u, --username="" Username

EXAMPLES

Login to a registry on your localhost

# docker login localhost:8080
