Configuration

providers:
  kubernetes:
    class: octodns_kubernetes.KubernetesSource
    hostnameAnnotations:
      - octodns-kubernetes.rybni.co/hostname # default
      - external-dns.alpha.kubernetes.io/hostname
    ttlAnnotations:
      - octodns-kubernetes.rybni.co/ttl # default
      - external-dns.alpha.kubernetes.io/ttl
    targetAnnotations:
      - octodns-kubernetes.rybni.co/target # default
      - external-dns.alpha.kubernetes.io/target

The kubeconfig is read from the file specified in the KUBECONFIG environment variable or from the default location. If it's not found, an in-cluster config is attempted.

Development

See the /script/ directory for some tools to help with the development process. They generally follow the Script to rule them all pattern. Most useful is ./script/bootstrap which will create a venv and install both the runtime and development related requirements. It will also hook up a pre-commit hook that covers most of what's run by CI.
