We just moved to kubernetes, but the engineer that helped launch it is on paternity leave before we had hoped (never trust a baby not to be eager!).
Now we're trying to do maintenance tasks and one off work and having nodes get killed in the middle of things.
I've looked at using kubernetes jobs for this, but that's overkill. We don't want to write manifest files for everything.
We just need long lived shell access to do this and that.
What's the pattern for this so your maintenance task doesn't get killed?
