[Pdns-users] PowerDNS Recursor Helm Chart with global transparency mode, seeking for feedback

[Vitali Quiering]

Hi list,

in our company we are using AWS EKS with the default CoreDNS setup that they provide.
Recently we have deployed the node-local-dns helm chart to avoid issue with AWS’ usage policies. For certain cases, we are an ESP and send a lot of emails, I developed a helm chart for PowerDNS Recursor because I couldn’t find any back in the day.

This chart has now evolved to a replacement of the node-local-dns daemonset. If deployed in transparency mode it will update iptables and add IPs to the listener config to allow transparent takeover of all DNS traffic throughout the cluster. Additionally you can still use a service IP to spread traffic over all pods.

The helm chart: https://artifacthub.io/packages/helm/klicktipp/powerdns-recursor, https://github.com/klicktipp/helm-charts/tree/main/charts/powerdns-recursor
The init and sidecar image: https://github.com/klicktipp/containers/tree/main/images/pdns-transparent-dns

I would love to get some feedback on this, even if it’s bad. :-D

Cheers,
Vitali
