docker login [--help] [-p|--password[=PASSWORD]] [-u|--username[=USERNAME]] [SERVER]
Log in to a Docker Registry located on the specified
SERVER. You can specify a URL or a
hostname for the

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.

sudo or be
root, except when:
dockergroup. This will impact the security of your system; the

$HOME/.docker/config.json on Linux or
%USERPROFILE%/.docker/config.json on Windows.
