I run a 2 node k3s cluster. There are a few small advantages over docker swarm, built-in network policies to lock down my VPN/Torrent pod being the main one.
Other than that writing kubernetes yaml files is a lot more verbose than docker-compose. Helm does make it bearable, though.
Due to real-life my migration to the cluster is real slow, but the goal is to move all my services over.
It’s not “better” than compose but I like it and it’s nice to have worked with it.
Depending on your level of caffeine tolerance/dependency actual coffee might be even better.
