Cloudflare Dynamic DNS Kubernetes Controller
1.1K
A small kubernetes controller that will create Cloudflare DNS records and watch for your dynamic IP address to change and update Cloudflare with the new IP.
kubectl create namespace cloudflare-dynamic-dns-controller
kubectl create secret -n cloudflare-dynamic-dns-controller generic cloudflare --from-literal=email=INSERT-EMAIL --from-literal=token=INSERT-TOKEN --from-literal=zone=INSERT-ZONE-ID
kubectl apply -n cloudflare-dynamic-dns-controller -f deploy.yml
To use the controller add the annotations to either a service or an ingress resource. For example:
---
apiVersion: v1
kind: Service
metadata:
name: "example-website"
annotations:
cloudflare-dynamic-dns.alpha.kubernetes.io/hostname: "hello.example.com"
cloudflare-dynamic-dns.alpha.kubernetes.io/proxied: "true"
spec:
type: NodePort
selector:
app: example-website
ports:
- protocol: TCP
port: 80
targetPort: 80
Currently there are only 2 supported annotations:
The name of the record. Note that this must be the full domain name including the zone. For example you must use hello.example.com instead of just hello
cloudflare-dynamic-dns.alpha.kubernetes.io/hostname: "hello.example.com"
Whether to use the Cloudflare proxy to take advantage of all the benefits of Cloudflare. This is recommended becuase it will hide your public IP.
cloudflare-dynamic-dns.alpha.kubernetes.io/proxied: "true"
