Run periodically until no pending CSRs remain.
### 9. Install Cilium (CNI)
Cilium is managed by Helm only — never via ArgoCD.
```bash
helm repo add cilium https://helm.cilium.io/
helm repo update
helm install cilium cilium/cilium \
helm upgrade --install cilium cilium/cilium \
--version 1.17.3 \
--namespace kube-system \
--set ipam.mode=kubernetes \
--set routingMode=tunnel \
--set tunnelProtocol=vxlan \
--set kubeProxyReplacement=true \
--set k8sServiceHost=10.1.71.65 \
--set k8sServicePort=6443 \
--set securityContext.capabilities.ciliumAgent="{CHOWN,KILL,NET_ADMIN,NET_RAW,IPC_LOCK,SYS_ADMIN,SYS_RESOURCE,DAC_OVERRIDE,FOWNER,SETGID,SETUID}" \
--set securityContext.capabilities.cleanCiliumState="{NET_ADMIN,SYS_ADMIN,SYS_RESOURCE}" \
--set cgroup.autoMount.enabled=false \
--set cgroup.hostRoot=/sys/fs/cgroup
--values talos/cilium/cilium-values.yaml \
--wait \
--timeout 5m
```
Note: The explicit `securityContext.capabilities` flags are required for Talos — Talos
restricts privileged container capabilities by default. The `cgroup.autoMount.enabled=false`
and `cgroup.hostRoot` flags are required because Talos manages cgroups itself.
Apply IP pools:
### 10. Verify Cluster
```bash
kubectl apply -f talos/cilium/ip-pools.yaml
```
Verify:
```bash
cilium status --wait
kubectl get ciliumloadbalancerippool
kubectl get ciliuml2announcementpolicy
```
**Important:** The `cilium-values.yaml` contains required Talos-specific overrides:
- `securityContext.capabilities` — removes `SYS_MODULE` (blocked by Talos permanently)
- `cgroup.autoMount.enabled: false` — Talos manages cgroups itself
- `l2announcements.interface: ens18` — Proxmox VMs use `ens18`, not `eth0`
- `l2podAnnouncements.interface: ens18` — same reason
### 10. Bootstrap ArgoCD
See `cluster/argocd/BOOTSTRAP.md` for the full ArgoCD bootstrap sequence.
Summary:
1. `kubectl apply -f cluster/argocd/namespace.yaml`
2. Add Gitea SSH host key to ArgoCD known hosts
3. Create `gitea-repo` secret with SSH private key at `~/.ssh/argocd_gitea`
4. `helm upgrade --install argocd argo/argo-cd --values cluster/argocd/values.yaml`
5. `kubectl apply -n argocd -f cluster/argocd/apps-of-apps.yaml`
### 11. Verify Cluster
```bash
kubectl get nodes
kubectl get pods -n kube-system
kubectl get pods -A | grep -v Running | grep -v Completed
cilium status --wait
```
All nodes should show `Ready`. Cilium pods should be `Running`.
### 11. Post-Install HA Setup
See output of `terraform output` for the full HA registration commands.
Register VMs with Proxmox HA and add to node-affinity rules once the
cluster is stable and the ISO is no longer needed for boot.
All nodes should show `Ready`. All pods should be `Running` or `Completed`.
