Yes, yes they are. And they're written down where you can read them yourself. And maybe even version controlled!

- GrinningFool 10y agoOn the other hand, tracing back a dockerfile that pulls in an obscure one-off base image, then repeating that all the way up the chain, you can find yourself left with a dozen Dockerfiles that you need to read in the right order to know what you have. That's if you can even find the original Dockerfiles - I recently ran into a situation where a container image was in the registry, but the original Dockerfile was completely lost. Docker/containers in general move the complexity to a different plane, but they only move it - they don't eliminate it. Care needs to be taken to avoid situations just like the one above - or any of a number of other pitfalls - or you end up with an environment that's far more complex to understand than a VM housing a monolithic dev environment.
