Now that you've built an image, you can share it. To share Docker images, you have to use a Docker
registry. The default registry is Docker Hub and is where all of the images you've used have come from.

> **Docker ID**
>
> A Docker ID lets you access Docker Hub, which is the world's largest library and community for container images. Create a [Docker ID](https://hub.docker.com/signup) for free if you don't have one.

## Create a repository

To push an image, you first need to create a repository on Docker Hub.

1. [Sign up](https://www.docker.com/pricing?utm_source=docker&utm_medium=webreferral&utm_campaign=docs_driven_upgrade) or Sign in to [Docker Hub](https://hub.docker.com).

2. Select the **Create Repository** button.

3. For the repository name, use `getting-started`. Make sure the **Visibility** is **Public**.

4. Select **Create**.

In the following image, you can see an example Docker command from Docker Hub. This command will push to this repository.

## Push the image

Let's try to push the image to Docker Hub.

1. In the command line, run the following commmand:

   ```console
   docker push docker/getting-started
   ```

   You'll see an error like this:

   ```console
   $ docker push docker/getting-started
   The push refers to repository [docker.io/docker/getting-started]
   An image does not exist locally with the tag: docker/getting-started
   ```

   This failure is expected because the image isn't tagged correctly yet.
   Docker is looking for an image name `docker/getting started`, but your
   local image is still named `getting-started`.
