Strato DynDNS Controller updates your domains' DNS records on STRATO AG using Kubernetes Custom Resources and Controller

THIS SOFTWARE IS IN NO WAY ASSOCIATED OR AFFILIATED WITH STRATO AG

A custom Controller is observing Domain CRs and syncing their desired state with STRATO DNS servers. You can either define explicitely an IPv4 address (Manual mode) or let the Controller discover you public IPv4 assigned to you by your ISP (Dynamic mode)

You’ll need a Kubernetes cluster to run against. You can use KIND or K3D to get a local cluster for testing, or run against a remote cluster. Note: Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster kubectl cluster-info shows).

1. Build and push your image to the location specified by IMG in Makefile:

# Image URL to use all building/pushing image targets
IMG_TAG ?= $(shell git rev-parse --short HEAD)
IMG_NAME ?= strato-dyndns
DOCKER_HUB_NAME ?= $(shell docker info | sed '/Username:/!d;s/.* //')
IMG ?= $(DOCKER_HUB_NAME)/$(IMG_NAME):$(IMG_TAG)

make docker-build docker-push

2. Deploy the controller to the cluster with the image using IMG:

make deploy

or

3. Deploy the controller to the cluster with the image using Helm chart:

helm install strato-dyndns config/helm/

4. Install Instances of Custom Resources:

Encode your STRATO DynDNS password for your domain or your STRATO DynDNS master password:

echo -n "password" | base64

Create a Secret containing the base64 encoded password for your Domain:

apiVersion: v1
kind: Secret
metadata:
  name: strato-dyndns-password
type: Opaque
data:
  password: cGFzc3dvcmQ=

Create a Domain pointing to the FQDN of your domain registered with STRATO and bind it with the Secret containing the password for this DynDNS account:

apiVersion: dyndns.contrib.strato.com/v1alpha1
kind: Domain
metadata:
  name: www-example-de
spec:
  fqdn: "www.example.de"
  enabled: true
  interval: 5
  password:
    name: strato-dyndns-password

Deploy these resources to your Kubernetes cluster:

kubectl apply -f config/samples/

To delete the CRDs from the cluster:

make uninstall

UnDeploy the controller to the cluster:

make undeploy

or if you have installed via Helm:

helm uninstall strato-dyndns

Please refer to our Contributing Guidelines

This project aims to follow the Kubernetes Operator pattern

It uses Controllers which provides a reconcile function responsible for synchronizing resources untile the desired state is reached on the cluster

1. Install the CRDs into the cluster:

make install

2. Run your controller (this will run in the foreground, so switch to a new terminal if you want to leave it running):

make run

NOTE: You can also run this in one step by running: make install run

If you are editing the API definitions, generate the manifests such as CRs or CRDs using:

make manifests

NOTE: Run make --help for more information on all potential make targets
