Goal 1:¶

Current: There are 2 VM running kubernetes on ubuntu on KVM VMs.

Wanted: 2 VM running kubernetes on ubuntu on LXC vm containers

## Goal 2:

Current: there is nfs running on ubuntu on KVM vm.
Wanted: NFS running elsewhere

How? maybe it is too hard. Post-pone this.

Goal 1 plan¶

1. add 2 vm on LXC using ubuntu base image
2. join the cluster of 10.0.4.11-12 k8s vms.
3. promote one of the newest as controlplane.
4. add newer nodes to round-robin of nginx proxy
5. demote the current controlplane
6. drain nodes on kvm, then remove the nodes
7. switch off the kvm-based vms.

Everything should be fine.

Additional check¶

• /root folder for each node
• /home/cruzza user folder for each node

Check and save before delete the node.

Outcome¶

Great outcomes are:

• performance (near metal machine and no layer)
• startup time (2 vs 20 seconds: 1/10)
• simple update for kernel (just update proxmox kernel and that's all)
• easier systemd group management
• no strange startup staff in kubernetes (no boot option specific for k8s)

Possible problem¶

It might not work at all. Funny, but true.
