Pushing your Docker image to the Docker Registry

Once a Docker image has been created, it's always best practice to store or save the image so that the next time you have to boot up the containers from your custom image, you don't have to bother about or remember the steps you performed earlier while creating it.

You can save an image either on a local machine or in an artifactory or to any of the public or private Docker Registries, such as Docker Hub, Quay, Google Container Registry, AWS Container Registry, and so on. In this recipe, we will learn how to save or push an image which we have created in one of our previous recipes to the Docker Hub.

Note

See the Building your first Go Docker image recipe.
