We will continue using ChartMuseum throughout the rest of the book, and I will leave it to you to decide whether Monocular is useful or a waste of computing resources.

We could have set up a container registry, but we didn't. There are too many tools in the market ranging from free solutions like Docker Registry (https://docs.docker.com/registry/) all the way until enterprise products like Docker Trusted Registry (https://docs.docker.com/ee/dtr/) and JFrog' Artifactory (https://www.jfrog.com/confluence/display/RTF/Docker+Registry). The problem is that Docker Registry (free version) is very insecure.

It provides only a very basic authentication. Still, the price is right (it's free). On the other hand, you might opt for one of the commercial solutions and leverage the additional features they provide. Never the less, I felt that for our use-case it is the best if we stick with Docker Hub. Almost everyone has an account there, and it is an excellent choice for the examples we're having. Once you translate the knowledge from here to your "real" processes, you should have no problem switching to any other container registry if you choose to do so. By now, you should have all the skills required to run a registry in your cluster.

All in all, we'll continue using Docker Hub for storing container images, and we'll run ChartMuseum in our cluster and use it to distribute Helm charts.

All that's left is for us to remove the charts we installed. We'll delete them all at once. Alternatively, you can delete the whole cluster if you do plan to make a break. In any case, the next chapter will start from scratch.
