I have no experience with Kubernetes but my understanding is that Erlang/OTP is conceptually much simpler but also answer a different problem. Some stuff overlap (like restarting services/apps) but not all: for example there is no autoscaling in Erlang/OTP. I know that some companies use both in their stack. Kubernetes is language agnostic.
Erlang/Elixir is amazing because it brings so much good things and they are not that difficult to learn with some experience with functional programming.
