> You should just develop your apps in/with/for containers. The container contains all the dependencies for your app. This way you never have to think about the host OS ever again; your app "just works" (once you hook up the networking, environment, secrets, storage, logging, etc for whatever is running your container). That sounds like a lot of extra work, but actually it's just standardizing the things you should already be dealing with even if you didn't use containers. The end result is your app works more reliably and you can run it anywhere.

This is a false sense of reproducibility. I encountered cases where container worked well on one machine and crashed or had weird bugs on another one.

This happens, but is pretty rare. Using containers generally leads to much more reliable portability than trying to manage all the dependencies by hand.
