This section is optional, and you will need a Docker Hub account if you want to follow along. If you do not complete this section, you can use the publicly available educative1/qsk-course:1.0 image in later steps.

There are many container registries available for use. However, you will use Docker Hub, as it is the most popular and the easiest to use. Feel free to visit hub.docker.com and have a look around.

Use the following commands to push your new image to Docker Hub. Remember to substitute {DockerHubId} with your own Docker Hub ID. If you try with {DockerHubId}, the operation will fail because there is no account against {DockerHubId}.
