Good progress today, but I didn't get the W I wanted. Not quite an L either. Maybe a "D" :)

Spinning up the openmetadata application in QA yielded top level errors saying that the helm chart failed to initialize, offering bogus advice about consulting the CLI.

That lead me to understand the fact that my kubectl configuration was out of date in that it didn't include the data-qa cluster I spun up for this project.

Mike wrote a script to dynamically generate your kubectl config, so that's fixed.

The app still won't spin up though. I noticed the following error when running kubectl describe pod:

  Warning  Failed     33m (x8 over 35m)      kubelet            Error: secret "pgsql-db-creds" not found

Then a bunch of flailing ensued, until Mike suggested the very helpful invocation:

Mike says we need a new Vault approle. I can't figure out how to create that. It seems like it might require a Vault CLI invocation, and we have no Vault CLI grimoire for such things. The Vault documentation offers some proposed incantations but I couldn't get any of them to work.

Tobias says he thought we weren't using approles in favor of service accounts.

I say I'm confused and look forward to being less so tomorrow :)
