Cloudflare DDNS in K8S cluster

[user16984]

Hi,

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.

bruno@K8S-Master:~/k8s$ cat ddns_v2.yaml
apiVersion: v1
kind: Pod
metadata:
name: ddns
labels:
purpose: ddns
spec:
containers:

• name: ddns
  image: oznu/cloudflare-ddns
  env:
  • 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.

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

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