Same! Jenkins master until we get the new thing working that Google released yesterday, then we can drop Jenkins. How do you cache your Dialyzer PLTs? We do triplet of elixir version, erlang version, checksum of lock file and tag a container layer with that tag and also make one called "latest" that is constantly overridden. If there's a new version of one of your dependencies, or you remove one or something, we just grab the latest layer because it's probably close enough.
