Kubernetes runs in default with host networking and reads cfddns-secrets. The Compose stack also uses host networking. Configure the API token and domain list from the relevant example; keep DNS names consistent with the ingress rules.

config.json.example is a separate configuration example. The current Compose file does not mount a config.json file. Check configuration against the pinned DDNS image when changing between environment and file-based settings.
