coredns v0.1.0

Networking

CoreDNS — a fast, pluggable DNS server (the Kubernetes default) configured with a simple Corefile. Runs as a caching forwarder out of the box. Deployed as a single host-networked Nomad service.

nomad-pack run coredns --registry nomploy
…or one line (add registry + run)
curl -fsSL https://packs.nomploy.com/install.sh | sh -s -- coredns

Needs nomad-pack on PATH. The script only adds the nomploy registry and runs this pack.

Readme

coredns

CoreDNS — a fast, flexible, plugin-based DNS server (the default DNS in Kubernetes). This pack ships it as a caching forwarder out of the box, and lets you drop in your own Corefile for split-horizon DNS, local zones, hosts entries, ad-blocking and more.

Single host-networked Nomad service. The Corefile is generated from your variables (no volume needed).

Deploy

nomad-pack registry add nomploy https://github.com/Nomploy/nomad-packs
nomad-pack run coredns --registry=nomploy

Configure

Variable Default Description
port 53 DNS port (TCP + UDP).
upstreams 1.1.1.1 9.9.9.9 Upstream resolvers the default Corefile forwards to.
corefile "" Full custom Corefile contents. Empty = the generated caching-forwarder config.
image coredns/coredns:latest Container image. Pin a tag in production.
resources { cpu = 300, memory = 256 } Task resources.

The default config forwards all queries to upstreams, caches, and enables log/errors/health. For anything richer (local zones with the file/hosts plugins, ad-blocking, per-domain routing), set corefile to your own Corefile. Port 53 must be free on the node — disable a host resolver (e.g. systemd-resolved) if it's bound there. Pin the job with constraints if clients target a specific node.
