Hello, I have 3 Raspberry Pi 4s which are currently in a Swarm configuration, but I would like to migrate to something else. My goal is to have high availability for some of the more critical services I host such as the DNS, reverse proxy (which are currently hosted outside of the Docker environment on another server) and whatever I think of after that. Should I set up a Kubernetes cluster with K3s, or maybe configure each Pi as a separate docker host and use keepalived? I am also not sure what is the best way to sync container storage between each node, if I go with Kubernetes I suppose I can use LongHorn? I would appreciate some advice or better ideas as a whole.
