This gist is how I personally deploy an arm64 version of unbound (for running on Raspberry Pi) configured as a recursive DNS resolver.

Use case is setting this up as the upstream resolver in PiHole (also running in K8S) in order to eliminate the need of a 3rd-party resolver (i.e. Cloudflare, Quad9), potentially avoiding DNS spoofing / poisoning / etc.

Service is exposed with a ClusterIP under 10.43.0.53 listening to both TCP/UDP on port 53.

TODO / Considerations:

• This still does not hide your DNS traffic from your ISP since root nameservers do not use DoH/DoT. Ultimately, this should run somewhere in the cloud (for example AWS EC2/ECS) and configured in DoH/DoT mode. This is also a fantastic opportunity to use ZeroTier for tying it all together to your local LAN without exposing your cloud resources to the public, while increasing security (ZT is encrypted).

Awesome regex

AWS ARN:

/^arn:aws\w*:\w+:\w*:(?:\d{12})?:(?:\w+\/(?:\w+|\*)|\w+:(?:\w+|\*)|\w+|\*)/
