Hmmm, yeah, I get the desire to keep production containers as minimal as possible.  I had asked a while ago if it was possible to get Python 3.7 on the bastion hosts, but was told that's not feasible because of the way the distros are packaged.  So, I seem to be stuck with having to flip back and forth between two hosts, which is a really awkward way to work.

As for the control-p issue, I believe the behavior I'm seeing is described in this stack overflow article.  But that describes a fix using docker commands, and I haven't figured out how to map that to the webservice wrapper.  To answer your question, though, my connection stack is:

Terminal window on MacOS
  ssh -t dev.tools.wmflabs.org tmux new -As spi-tools-dev
    become spi-tools-dev
      webservice --backend=kubernetes python3.7 shell

Hello Roy,
The container environment for webservice shell is the same image as the runtime containers for a service, so I'd rather not support ssh in the containers because they need to be light-weight, limited and including that would raise some interesting security issues in the cluster otherwise. The workflow does need some work, though, and we are experimenting with ways to make it more sensible.

On the CTRL-P issue, I'm not entirely sure what you mean and might need more information about your setup. That usually is dictated by the shell you are using rather than anything to do with Kubernetes. In some shells, I know you need to use SHIFT-CTRL-P. I have no issues on my Mac. What client are you using the connect via SSH? I might be able to recreate the issue and figure out a fix.

The bastion hosts don't have python3.7, and the k8s hosts don't have ssh, so "git pull" and "git push" don't work.  Which means I need to keep flipping back and forth between the two during development.  Is there some way to get ssh working on the k8s hosts, so I can do everything in one place?

The other annoyance is that when you connect with "webservice --backend=kubernetes python3.7 shell", the connection eats control-p's  Is there some way to turn that off, or at least reconfigure it to use a different command character?
