Checks metallb speaker pods if they announce some services. If they do, assign a given floating ip on hetzner to the k8s node that announces.

## Getting Started

The deployment will use helm and the chart in `chart/metallb-ip-floater`.  
You will need a hcloud api token and the name of your floating IP. Also your k8s nodes should be labeled in hcloud.  
Expose these information to the floater as described in this example:

```yaml
env:
  - name: METALLB_IP_FLOATER_LABELSELECTOR
    value: "kops.k8s.io/instance-role=Node"
  - name: METALLB_IP_FLOATER_HCLOUD_TOKEN
    value: "define_it"
  - name: METALLB_IP_FLOATER_FLOATING_IP_NAME
    value: "define_it"
```

you can also create a secret manually with these information and reference the existing secret like this in the `values.yaml`:

```yaml
externalConfigSecret:
  enabled: true
  name: "my-existing-secret"
```

Now you are able to deploy:

```bash
kubectl create namespace metallb-ip-floater
cd chart/metallb-ip-floater
helm upgrade --install -f values.yaml -n metallb-ip-floater metallb-ip-floater ./
```
