Summary

Containers are a wonderful method of hosting applications. You can spin up more containers on your hardware than you’d be able to with VMs, which will definitely save resources. While not all applications can be run inside containers, it’s a very useful tool to have available. In this chapter, we looked at both Docker and LXD. While Docker is better for cross-platform applications, LXD is simpler to use but is very flexible. We started out by discussing the differences between these two solutions, then we experimented with both creating containers and looking at how to manage them.

In the next chapter, we will expand our knowledge of containers even further and take a look at orchestration, which allows us to manage multiple containers more efficiently. This will be the chapter where all of the concepts relating to containers come together.
