NAME
docke-login- Authenticate to a registry
SYNOPSIS
docker login [OPTIONS] [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://registr-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 docke-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
[la]https://docs.docker.com/engine/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.
EXAMPLES
Login to a registry on your localhost
# docker login localhost:8080
