-> 1. The included behaviour of Talos, k3s or k0s is that all nodes are able to run workloads, **including** the controller nodes. **Worker nodes** are therefore **optional**.

 > 2. Do you have 3 or more nodes? It is highly recommended to make 3 of them controller nodes for a highly available control plane.
 > 3. Running the cluster on Proxmox VE? My thoughts and recommendations about that are documented [here](https://onedr0p.github.io/home-ops/notes/proxmox-considerations.html).
