LGTM

#327 also mentions porting authProxyPort for kibana but it looks like httpPort could be used, is that right?

Yes I think httpPort should be used for that.

I posted the mention about authProxyPort needing to be ported, and I still believe it should be.
After all, if you use any kind of proxy as sidecar of any container, the service.yaml will need to be pointed to the port of the proxy, whereas the main container itself will be listening on a different port. As it is now, both are configured with httpPort which would never work. (Well, actually it will work, it will just bypass the proxy entirely, which is not what you want).
