# PDNS example for Kubernetes
|
|
|
|
## Files
|
|
- master-daemonset.yaml : Daemonset for PDNS supermaster
|
|
- slave-daemonset.yaml : Daemonset for PDNS slaves
|
|
- admin-dashboard.yaml : Deployment for PDNS-Admin Web Dashboard
|
|
- mariadb.yaml : Example Mysql Deployment
|
|
|
|
## Example setup
|
|
|
|
This example deploys a supermaster and two slaves on the host network, so pdns can be reached from external networks. Access to the admin-dashboard has to be configured separately with ingress. The admin-dashboard uses a kubernetes clusterip service to use the supermaster-api. Supermaster, slaves and dashboard use the same MariaDB example deployment with different databases (not recommended for production environments).
|
|
For signed AXFR you have to manually deploy TSIG Keys to you supermaster and slaves (https://doc.powerdns.com/authoritative/tsig.html).
|
|
|
|
## Requirements
|
|
|
|
### Node Labels
|
|
The Daemonsets use node-role labels as nodeSelector:
|
|
|
|
kubectl label node node1 node-role.kubernetes.io/pdns-master=true
|
|
kubectl label node node2 node-role.kubernetes.io/pdns-slave=true
|
|
kubectl label node node3 node-role.kubernetes.io/pdns-slave=true
|
|
|
|
Any other node labels will also work.
|
|
|
|
### Service Names
|
|
Service names in the pdns namespace **must not** start with 'pdns' or they will break the pdns.conf environment templating.
|
|
|
|
### Pod-CIDR
|
|
Replace "10.244.0.0/16" in the manifests with your cluster's pod-cidr.
|
|
|
|
### Node IPs
|
|
Replace IPs and hostnames in the daemonset environments with your own node IPs and domains.
|
|
|
|
Used in this example:
|
|
| component | host | ip |
|
|
|--|--|--|
|
|
| supermaster | ns1.example.com | 10.0.0.1 |
|
|
| slave1 | ns2.example.com | 10.0.0.2 |
|
|
| slave2 | ns3.example.com | 10.0.0.3 |
|
