## Ansible

```bash

docker build -t ansible-k3s ./ansible

docker run --rm -it \

    -v $(pwd)/inventory.yml:/config/inventory.yml \

    -v $(pwd)/hetzner_infra/.ssh/k3s_hetzner_key:/secrets/ssh_key \

    ansible-k3s

ansible-playbook playbook_k3s_deploy.yml

cat kubeconfig

```

or use the [prebuilt](https://hub.docker.com/repository/docker/ujstor/ansible-k3s-deploy/general) image.

## Helm

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

```bash

cd helm/system/cilium

helm install cilium . -n kube-system

```

### Install Argo CD:

```bash

kubectl create namespace gitops

cd helm/system/argo-cd

helm install argocd . -n gitops

```

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

```bash

cd helm

kubectl apply -f aoa.yaml -n gitops

``````

The cluster will be automatically bootstrapped.
