 # metallb-ip-floater
 
+[![status-badge](https://woodpecker.uploadfilter24.eu/api/badges/7/status.svg)](https://woodpecker.uploadfilter24.eu/repos/7)
+
+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 ./
+```
