## Helm

### Install Cilium in the `kube-system` namespace:

```bash

cd gitops/helm/system/cilium

helm install cilium . -n kube-system

```

### Install Argo CD:

```bash

kubectl create namespace gitops

cd gitops/helm/system/argo-cd

helm install argocd . -n gitops

```

### Apply `aoa.yaml` in the `gitops` namespace:

```bash

cd gitops/helm

kubectl apply -f aoa.yaml -n gitops

```

The cluster will be automatically bootstrapped.
