Getting Started with Docker.io

How do I use Docker.io?

In this section we're going to introduce you, very quickly!, to Docker.io and create an account.

Docker.io is the central hub for Docker. It helps you to manage Docker and its components. It provides services such as:

• Hosting images.
• User authentication.
• Automated image builds and work flow tools like build triggers and web hooks.
• Integration with GitHub and BitBucket.

Docker.io helps you collaborate with colleagues and get the most out of Docker.

In order to use Docker.io you will need to register an account. Don't panic! It's totally free and really easy.

Creating a Docker.io Account

There are two ways you can create a Docker.io account:

• Via the web, or
• Via the command line.

Sign up via the web!

Fill in the sign-up form and choose your user name and specify some details such as an email address.

Signup via the command line

You can also create a Docker.io account via the command line using the docker login command.

$ sudo docker login

Confirm your email

Once you've filled in the form then check your email for a welcome message and activate your account.

Login!

Then you can login using the web console:

Or via the command line and the docker login command:

$ sudo docker login

Now your Docker.io account is active and ready for you to use!
