I’ll post more later (reply here to remind me), but I have your exact setup. It’s a great way to learn k8s and yes, it’s going to be an uphill battle for learning - but the payoff is worth it. Both for your professional career and your homelab. It’s the big leagues.
For your questions, no to all of them. Once you learn some of it the rest kinda falls together.
I’m going into a meeting, but I’ll post here with how I do it later. In the mean time, pick one and only one container you want to get started with. Stateless is easier to start with compared to something that needs volumes. Piece by piece brick by brick you will add more to your knowledge and understanding. Don’t try to take it all on day one. First just get a container running. Then access via a port and http. Then proxy. Then certs. Piece by piece, brick by brick. Take small victories, if you try to say “tomorrow everything will be on k8s” you’re setting yourself up for anger and frustration.
Glad to be of help. It is the right decision, I have no regrets if migrating, but it is a long process. Just getting my first few services running was months, just so you are aware of that commitment, but it’s worth it.
