CoreDNS VS dnscrypt-proxy

CoreDNS supports this via the bind plugin.

I'd like to use Cloudflare's 1.1.1.1 and 1.0.0.1 nameservers in Kubernetes, alongside DNS over TLS. It looks like I can do it using core-dns. I need to setup the following somehow:

Shamless plug for CoreDNS. Much better DNS server than classic bind9. And of course there's already a nice container image for it.

But another approach that could work in Kubernetes, because the DNS servers are within the cluster itself, would be to work directly with the DNS server pods. In most Kubernetes clusters, whether standalone or managed (GKE, AKS, EKS), the cluster DNS is either coredns or kube-dns. That was great to minimize how much configuration options we’d need to support. We realized we could edit the coredns or kube-dns configmap resources to enable their log option, which would make them log all the queries they handle. We’ll cover exactly how it’s done in more detail below.

CoreDNS has an ectd plugin, so your service could add entries to a database, which is used as record source. Not the same mechanism as you have described, but it will get the job done. Also this is what Kubetnetes does for incluster dns records.

nevermind there's caddy builtin upgrade method https://github.com/coredns/coredns/issues/6034

Coredns can be spun up in a docker container, just starting to get into it myself

CoreDNS is a pretty good DNS server.

There is more than one way to do this but I have decided to use dnscrypt-proxy. We will not be using dnscrypt for the dnscrypt protocol though you could elect to use that as the underlying DNS protocol. dnscrypt-proxy lets's us use a SOCKS5 proxy through which the DNS queries will be sent. We will use a Tor SOCKS5 proxy here. You can choose which protocols should be enabled and which ones should be disabled. There are two points:

I tried installing the RPM from the Fedora repos but it's out-of-date and there were no instructions on how to get it operational, so I went with the manual approach as per their wiki: https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Installation-linux

This is awesome, thanks -- going to look into that now. I found SmartDNS interesting and thought I would share it, it's pretty simple to setup. I can see why it's Chinese focused, they have "interesting" internet access over there :-).

I have been looking into DNS quite a bit lately (Unbound, etc), as DNS lookup performance has been pretty subpar lately. I'm in Perth, Australia, and we're pretty remote so our latency is meh at best, and Cloudflare performance has been all over the shop lately, I think they're having issues in WA). DNS can also cause really routing issues here sometimes as we get better latency to Singapore than Sydney, so we might get shunted off to SG.

I've also been using dnscrypt-proxy2 (https://github.com/DNSCrypt/dnscrypt-proxy) for a while, but the above issues with Cloudflares DNS is what triggered me to look into other options.

I use a min-cache-ttl of 15 minutes, which seems to work well.

Thank you for sharing this tip about, looking into this now :).

Sure. I run dnscrypt_proxy behind a pihole. https://github.com/DNSCrypt/dnscrypt-proxy
