Notes
  +
  +
<pre>
  +
The init: true key in Compose automatically runs Docker’s built-in tini, even without the manual entrypoint. You can omit the ENTRYPOINT line in Dockerfile if you prefer this simpler route.
  +
  +
You can change user: "nsd" to a custom unprivileged UID if desired.
  +
  +
You can also bind it to port 8053 inside the container and map externally to 53 if you’re not comfortable with the privilege cap:
  +
  +
ports:
  +
- "53:8053/tcp"
  +
- "53:8053/udp"
  +
  +
  +
and adjust port: 8053 in nsd.conf.
