docker-login - Log in to a Docker registry
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
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.
Login to a registry on your localhost
# docker login localhost:8080
docker-logout(1) to log out from a Docker registry.
