+## Kubernetes
+
+I am currenly running in kubernetes cluster as a cronjob checking periodically. Substitute `${IMAGE}` in `job.yml` manually or using CI script similar to: https://github.com/KevinMidboe/cloudflare-ddns/blob/main/.drone.yml#L49-L51. 
+
+After job is created you also want to set environment variables from kubernetes secret, example `.kuberenetes/secret.yml`:
+
+```yaml
+apiVersion: v1
+kind: Secret
+metadata:
+  name: secret-env-values
+  namespace: cloudflare-ddns
+type: Opaque
+data:
+  API_KEY: BASE_64_ENCODED_CLOUDFLARE_API_KEY
+  DDNS_ZONE: BASE64_ENCODED_CLOUDFLARE_ZONE_ID
+```
+
+```
+kubectl apply -f .kuberenetes/secret.yml
+```
