Traefik PowerDNS Updater is a Python-based Kubernetes application designed to streamline DNS management. It monitors Traefik IngressRoutes within your Kubernetes cluster and automatically creates or updates DNS records in PowerDNS.
Components:
- PTS Tool (PowerDNS Traefik Sync) Checks if Traefik ingressroutes were added or deleted and updates the PowerDNS via API
- HA Postgres Database: Database of DNS records for the current state (by Postgres Zalando Operator)
The following requirements are necessary to install the project.
- A running Kubernetes cluster
- kubectl installed and configured
- git installed and configured
- jq installed
- makefile installed
- Ingresscontroller Traefik
- Zalando Postgres Operator (will be installed if not already done )
The tool was tested with PowerDNS Authoritative Server 4.9.0.
The PowerDNS Traefik Sync Tool can be run with two different modes:
- Normal: This is the simpler method, which uses the external IP of the Traefik service and points directly to that IP address (A-Record).
- Advanced: The advanced mode requires the
K8S_INGRESSvariable, which directs all domains to the configured K8S_INGRESS domain using a CNAME record.
The deployment is handled by a Makefile. Please always use a released tag version instead of the unstable main branch!
git clone https://github.com/Tim-herbie/k8s_powerdns_traefik_sync.gitBefore you can deploy it, you have at least to adjust the following Makefile variables:
Standard pts method:
- PDNS_API_URL
- DNS_ZONE
- TRAEFIK_NAMESPACE (only necessary for the standard pts method)
Advanced pts method:
- PDNS_API_URL
- DNS_ZONE
- K8S_INGRESS (only necessary for the advanced pts method)
