At the heart of any Kubernetes deployment strategy lies The Pod. The workhorse of distributed container solutions, the Kubernetes Pod glues together a bunch of containers to a single networking stack and process namespace. Pod processes can communicate with one another over loopback (127.0.0.1), and signal each other using POSIX signal(7) mechanics. Strange then, that
