I don’t use any GUI… I use terraform in the terminal or via CI/CD. There is an API and also a Terraform provider for Proxmox, and I can use that, together with Ansible and shell scripts to manage VMs, but I was looking for k8s support.

Again, it works fine for small environments, with a bit of manual work and human intervention, but for larger ones, I need a bit more. I moved away from a few VMs acting as k8s nodes, to k8s as a service (at work).
