Summary

In this chapter, we learned how container network isolation can be leveraged to allow network segregation for each container that's running through network namespaces. These activities seem complex but thankfully, with the help of a container runtime, the steps are almost automated. We learned how to manage container networking with Podman and how to interconnect two or more containers. Finally, we learned how to expose a container's network ports outside of the underlying host and what kind of limitations we can expect while networking for rootless containers.

In the next chapter, we will discover the main differences between Docker and Podman. This will be useful for advanced users, but also for novice ones, to understand what we can expect by comparing these two container engines.
