Task #93
Updated by Daniele Cruciani 10 days ago
## 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.
