I have a kubernetes cluster.
I can easily connect to a remote container, and run a shell node connecting to live production erlang node:

$ kubectl exec myapp-2431125679-cwqvt -i -t -- iex --name debugging@127.0.0.1 --remsh myliveapp@127.0.0.1 --cookie my_secret_cookie

Erlang/OTP 18 [erts-7.3.1] [source] [64-bit] [smp:2:2] [async-threads:10] [kernel-poll:false]

Interactive Elixir (1.3.4) - press Ctrl+C to exit (type h() ENTER for help)
iex(myliveapp@127.0.0.1)1>

What I need though is to be able to run an :observer against a remote live production erlang node.
I can do that too:

1. kill local epmd process:

killall epmd

1. forward selected remote ports to my local machine:

kubectl port-forward myapp-2431125679-cwqvt 35609 4369

I know that my app runs on port 35609 on a remote container, and 4369 is the port epmd runs by default, which is the case for my remote container.

1. run:

iex --name debugging@127.0.0.1 --cookie marketplace -e ':observer.start()'

1. select the app I'm interested in from the top menu in :observer .
   My questions are:
2. can this be done simpler?
3. is there anything I should know about kubernetes, to make it possible to write a one-liner that'd connect to a remote node and do what I want?
   Ultimately, can I make this process a one-liner or turn it into a shell script?
   Right now killing epmd looks really-really dirty, I'd love to be able avoid that specifically.
