K3S on its own will require separate VMs/metal nodes to spin up a multi-node cluster. Eventually they I run Rook managed Ceph on a small ARM-based k3s cluster. I dug into it the best I could but saw no connectivity issues between hosts and kube-proxy was healthy. Bash scripts are included for your convenience. To keep it really short, I have a Proxmox cluster with 3 nodes. I've deployed the entire setup using ArgoCD 2. However, when I execute a command I get "error: no Auth Provider found for name "oidc"".

I have a site-site wireguard mesh configured on some openwrt routers, and VMs behind each router that are just using the local remote IP of the other VMs for setting up k3s. I gave a quick 15 minute talk on Civo Cloud's community meetup yesterday about how to very quickly get started with monitoring Kubernetes using Prometheus Operator (specifically using the Helm Chart). org/), and installing k3s there?
