My x86_64 / amd64 nodes are built on top of Proxmox instead of bare metal nodes due to the hardware I have on hand. These will primarily be worker nodes in the cluster with one of the arm64 nodes acting as master. Please see the amd64 README.md for more information.
My arm64 nodes consists of three 8GB Raspberry Pi 4 worker nodes. My long term goal is to have core services run on the low power arm nodes and in the event of a power failure, allow for longer overall runtime with my UPS by shutting down the higher power x86_64 nodes and running network + arm nodes for a longer period of time. Please see the arm64 README.md for more information.
Once the cluster is built for the above architectures, check out WRMilling/k3s-gitops Cluster Bootstrap for bootstrapping the apps onto the infrastructure.
