That wraps up what we have planned for today.
Then we explored Overlay Filesystems and Container Networking basics. These are the extra bits that make containers work.
All container engines, be it podman, docker, rkt, etc… They all use the same Linux components. Now that the Registry API and Image File Format have been standardized, the underlying container engine can be changed with little affect to the runtime environment. Open source and open standards have provided a vast amount of flexibility.
Thank you for your time and participation!
