It fits into industry-standard deployment systems, yes, but not without sacrificing some inherent benefits of the Erlang platform. In particular, hot upgrades and downgrades are no longer there, as Docker images try pretty hard to be immutable. Of course there are also the effects of flushing all server-local cache and/or memoization upon deploys too. Probably a bunch of other stuff I can't think of now also.

So far I've preferred to stick to the Erlang way of doing things because it let me be laziest and it hasn't failed me, but someday I would like to see tools that allow the Erlang way and the e.g., K8s way to work together.
