Kubernetes

This directory has example plain Kubernetes manifests for running DDNS-updater in Kubernetes.

The Manifests have additional Kustomize overlays, which can be used to add an ingress-route to ddns-updater.

1. Download the template files from the base directory. For example with:

   curl -O https://raw.githubusercontent.com/qdm12/ddns-updater/master/k8s/base/deployment.yaml
   curl -O https://raw.githubusercontent.com/qdm12/ddns-updater/master/k8s/base/secret-config.yaml
   curl -O https://raw.githubusercontent.com/qdm12/ddns-updater/master/k8s/base/service.yaml
   curl -O https://raw.githubusercontent.com/qdm12/ddns-updater/master/k8s/base/kustomization.yaml

2. Modify secret-config.yaml as described in the project readme

3. Use kubectl to apply the manifest:

   kubectl apply -k .

4. Connect the the web UI with a kubectl port-forward

   kubectl port-forward svc/ddns-updater 8080:80

The web UI should now be available at http://localhost:8080.

Advanced usage

Kustomize overlays can extend the installation:

• overlay/with-ingress - Basic HTTP Ingress ressource
• overlay/with-ingress-tls-cert-manager - Basic HTTPS Ingress ressource which uses cert-manager to create certificates.

To install with the overlay just change dirctory in the overlay folder you want to install and hit kubectl apply -k . .
