Cloudflare DDNS in K8S cluster


I'm trying to set up a DDNS in my kubernetes cluster. I usually to run it in an old docker cluster. However, I do not find how to use the same image in kubernetes...
Is anyone able to run the image below or any other? All I need is accessing my internal lab via cloudflare dns service. I do not have fixed IP at home.
I have this YAML file. But I assume it may be not correct.

[email protected]:~/k8s$ cat ddns_v2.yaml
apiVersion: v1
kind: Pod
name: ddns
purpose: ddns

  • name: ddns
    image: oznu/cloudflare-ddns
    • name: API_KEY
      value: MY_KEY
    • name: ZONE
      value: MY_DOMAIN
    • name: SUBDOMAIN
      value: MY_SUBDOMAIN

I always get the same output. The key is correct.

[email protected]:~/k8s$ kubectl logs ddns
[s6-init] making user provided files available at /var/run/s6/etc…exited 0.
[s6-init] ensuring user provided files have correct perms…exited 0.

Make sure the API_KEY is correct. You can
get your scoped CloudFlare API Token here:

[cont-init.d] 30-cloudflare-setup: exited 1.
[cont-finish.d] executing container finish scripts…
[cont-finish.d] 50-remove-record: executing…
[cont-finish.d] 50-remove-record: exited 0.
[cont-finish.d] done.
[s6-finish] waiting for services.
[s6-finish] sending all processes the TERM signal.
[s6-finish] sending all processes the KILL signal and exiting.

An API Key requires an email address. It does mention API Token, so maybe you can try one of those.
