Re:Managing my personnal servers in 2020 with K3s

I've setup many a Linux server over the years. Generally I set it up, and it works great for ages, but when something eventually does break, it's been so long since I touched it that I'm lost.
Another issue is "works on my machine" - with containers I don't need to worry about what packages and versions are available in the package manager. I can run a container anywhere.
And in the case where there is a hardware failure, it takes an age to get everything back up and running. Using containers forces you to have everything setup in a reproducible way.
If you're not familiar with containers, I understand that the learning curve might seem steep, or that it might seem too complicated, but it's honestly not.
Now, I wouldn't personally advocate for running k8s, or even k3s, on a personal server - they really are very complicated, and k8s in particular uses a lot of CPU and RAM to do even nothing. But Docker Compose and Swarm are pretty simple really, and life before them was absolutely worse - I love these tools.
