## Step 4 — Cilium
Values in [configs/cilium/values.yaml](../configs/cilium/values.yaml); `upgrade --install` is
safe to re-run.
```bash
export KUBECONFIG=$PWD/lab1.kubeconfig
helm repo add cilium https://helm.cilium.io && helm repo update
helm install cilium cilium/cilium --version 1.20.2 -n kube-system --set ipam.mode=kubernetes
clusterctl get kubeconfig lab1 --kubeconfig ~/.kube/lab-mgmt.kubeconfig > ~/.kube/lab1.kubeconfig
chmod 600 ~/.kube/lab1.kubeconfig
export KUBECONFIG=~/.kube/lab1.kubeconfig
helm repo add cilium https://helm.cilium.io && helm repo update cilium
helm upgrade --install cilium cilium/cilium --version 1.20.2 -n kube-system \
-f configs/cilium/values.yaml --wait --timeout 10m
kubectl get nodes # both Ready
kubectl -n kube-system get pods -o wide # cilium DaemonSet 2/2, operator 1/1, coredns Running
```
`ipam.mode=kubernetes` uses the pod CIDR from `clusterNetwork` instead of Cilium's `10.0.0.0/8` default.
- `ipam.mode=kubernetes` uses the pod CIDR from `clusterNetwork` instead of Cilium's `10.0.0.0/8` default.
- `operator.replicas: 1`: the default 2 replicas with node anti-affinity put one on a worker, and a
kube-system pod without a PDB blocks scale-down to zero.
- kube-proxy stays (kubeadm default); no kube-proxy replacement in this phase.
