(potentially) interestingly Heroku uses containers as part of their PAAS, so actually your workloads are using containers, they're just handling the complexity of that for you :) Personally I think knowing something about Docker/containers is a good plan, useful for testing on-laptop dev etc, however kubernetes is a fairly complex system and if you don't need it, and you're happy with your current process, I wouldn't rush to it.
