Leader Election

[mruoss]

I actually already implemented a simple version of this using k8s lease resource so we can use the k8s API for leader election. It's very beta and code is ugly as hell. Merely a POC. But cleaned up and dressed nicely, this could be the approach. wdyt @sleipnir?

I think it makes sense. I will test with my Operator

That would mean a lot. I ran some rudimentary tests locally by running Kompost with BONNY_POD_NAME=different-value iex -S mix, but some longer lasting test with a real deployment would be nice!

I think we could map a Process (GenServer) using the global type registry to perform the election. However this approach requires Operator to be running on a cluster of nodes, this responsibility could be delegated to the end user to avoid the inherent complexities of implementing this directly in Bonny. Leaving Bonny only the responsibility of communicating with the k8s API.

wdyt @mruoss ?

Forget what I said, I saw that the Leader Election API (Lease API) itself takes care of this :D
