cf-dns-bot - Automate DNS records from your kubernetes cluster using cloudflare

This tool allows you to manage DNS records when using cloudflare for example to build availability zones dynamically.

Deployment

  • Create a k8s service account with the permissions get, list, watch on nodes

  • Spawn the container as deployment (only one replica supported at the moment)

  • Set CF_API_KEY and CF_API_EMAIL as env variables inside the container

  • take a look at deploy.yaml to get a full-featured deployment with RBAC.

Usage

To indicate cf-dns-bot that it should manage dns records for a node, add a label:

domainmanager.deinstapel.de: "yes"

After that, you can add annotations for the node which get reflected into the cloudflare DNS records automatically: By default, domainmanager will fetch IP addresses for the node by using a DNS lookup on the nodes hostname extracted from the kubernetes.io/hostname label.

Adding records:

$domain/domainmanager: "true"

Removing Records:

$domain/domainmanager: "false"
