5. What are some ways containers can communicate within the same pod?

Go back and review multi-container pod types and content on decoupling if you can’t easily answer these questions.We touched on adding a second logging and a readiness container in a previous chapter and will work more wit

But I don't found mentions about IPC, loopback, etc... on this chapter.
