basher83 Omni + Proxmox Infrastructure Provider
Operational tooling for Talos Linux Kubernetes clusters via Sidero Omni with Proxmox infrastructure provider.
Provider Operations
Use ${CLAUDE_PLUGIN_ROOT}/skills/omni-talos/scripts/provider-ctl.py for provider management:
| Task | Command |
|---|---|
| Check status | ${CLAUDE_PLUGIN_ROOT}/skills/omni-talos/scripts/provider-ctl.py --status |
| View logs | ${CLAUDE_PLUGIN_ROOT}/skills/omni-talos/scripts/provider-ctl.py --logs 50 |
| Raw JSON logs | ${CLAUDE_PLUGIN_ROOT}/skills/omni-talos/scripts/provider-ctl.py --logs 50 --raw |
| Restart provider | ${CLAUDE_PLUGIN_ROOT}/skills/omni-talos/scripts/provider-ctl.py --restart |
The provider runs in Foxtrot LXC CT 200. The script reaches Foxtrot with
Tailscale SSH and executes provider commands through pct exec. Override its
defaults with OMNI_PROVIDER_HOST, OMNI_PROVIDER_CT, or
OMNI_PROVIDER_SERVICE when the deployment topology changes. The provider
container is discovered from its Docker Compose service label;
OMNI_PROVIDER_CONTAINER remains available as an explicit override.
Current Deployment
| Component | Location | IP | Endpoint |
|---|---|---|---|
| Omni | Holly (VMID 101, Quantum) | 192.168.10.20 | omni.spaceships.work |
| Proxmox Provider | Foxtrot LXC (CT 200, Matrix) | 192.168.3.10 | L2 adjacent to Talos VMs |
| Target Cluster | Matrix (Foxtrot/Golf/Hotel) | 192.168.3.{5,6,7} | Proxmox API |
| Storage | CEPH RBD | — | vm_ssd pool |
Quick Reference
omnictl commands:
omnictl cluster status <cluster-name>
omnictl get machines -l omni.sidero.dev/cluster=<cluster-name>
omnictl get machineclasses
omnictl apply -f machine-classes/<name>.yaml
omnictl cluster template sync -f clusters/<name>.yaml
Note: --cluster flag does not exist. Use label selector -l instead.
MachineClass minimal example:
metadata:
namespace: default
type: MachineClasses.omni.sidero.dev
id: matrix-worker
spec:
autoprovision:
providerid: matrix-cluster
providerdata: |
cores: 4
memory: 16384
disk_size: 100
storage_selector: name == "vm_ssd"
node: foxtrot
See references/machine-classes.md for full field reference.
Key Constraints
| Constraint | Details |
|---|---|
| L2 adjacency | Provider MUST be on same L2 as Talos VMs (Foxtrot LXC) |
CEL type reserved |
Use name only for storage selectors |
| Hostname bug | Use :local-fix tag, not :latest |
| No CP pinning | Omni allows only 1 ControlPlane section per template |
| No VM migration | Destroys node state — destroy/recreate instead |
| Split-horizon DNS | omni.spaceships.work → 192.168.10.20 (LAN) |
