not at all, but our devops guy ragequit the job and I want to be able to help piece things together if fire emerges, or help the team. Every engineer has some knowledge so together we're able to handle most of it. I want to use this opportunity to learn more.

It's sad that you assume the worst in people.

This is almost exactly how I became devops in the first place - the existing guy quit suddenly and I had to pick up the pieces in a hurry.

If you're already comfortable with the basics, then focus on one particular element and master it. The other bits will come over time. I recommend Kubernetes as a focus, given your list.

Keep in mind at all times that the infrastructure serves the business.

Hey, no judgement, and good for you for turning up for your team!

Hey, we have all been there ;)

At least he is trying to learn now instead of pulling a brillant paula.
