Your free Docker ID grants you access to Docker services such as the Docker Store, Docker Cloud, Docker Hub repositories, and some beta programs. Your Docker ID becomes repository namespace used by hosted services such as Docker Hub and Docker Cloud. All you need is an email address.
This account also allows you to log in to services such as the Docker Support Center, the Docker Forums, and the Docker Success portal.
Your Docker ID becomes your user namespace for hosted Docker services, and becomes your username on the Docker Forums.
Go to the Docker Cloud sign up page.
Enter a username that will become your Docker ID.
Your Docker ID must be between 4 and 30 characters long, and can only contain numbers and lowercase letters.
Enter a unique, valid email address.
Enter a password between 6 and 128 characters long.
Click Sign Up.
Docker sends a verification email to the address you provided.
Click the link in the email to verify your address.
Note: You cannot log in with your Docker ID until you verify your email address.
Once you register and verify your Docker ID email address, you can log in to Docker services.
For Docker Cloud, Hub, and Store, log in using the web interface.
You can also log in using the
docker login command. (You can read more about
docker login here.)
Warning: When you use the
docker logincommand, your credentials are stored in your home directory in
.docker/config.json. The password is base64 encoded in this file. If you require secure storage for this password, use the Docker credential helpers.
Once you create and verify your Docker ID, you can also update it using the Docker Accounts API.
