In this chapter, you learned how to work with containers that are based on existing images. We showed how to run, stop, start, and remove a container. Then, we inspected the metadata of a container, extracted the logs of it, and learned how to run an arbitrary process in an already-running container. Last but not least, we dug a bit deeper and investigated how containers work and what features of the underlying Linux operating system they leverage.
In the next chapter, you're going to learn what container images are and how we can build and share our own custom images. We're also discussing the best practices commonly used when building custom images, such as minimizing their size and leveraging the image cache. Stay tuned!
