Summary

In this chapter, we explored a fundamental topic of container management – their creation. This step is mandatory if we want to customize, keep updated, and manage our container infrastructure correctly. We learned that Podman is often partnered with another tool called Buildah that can help us in the process of container image building. This tool has a lot of options, like Podman, and shares a lot of them with it (storage included!). Finally, we went through the different strategies that Buildah offers us to build new container images, and one of them is actually inherited by the Docker ecosystem – the Dockerfile.

This chapter is only an introduction to the topic of container image building; we will discover more advanced techniques in the next chapter!
