# Published multi-architecture image. Pin an exact version in production:

# instead, build it first (see deploy/docker/Dockerfile) and set
# NXDNS_IMAGE=nxdns.

# `run --config` makes the file the sole source of configuration: nxdns
# reconciles the database onto ./etc-nxdns/config.zon at every start, and
# rejects configuration writes from the admin UI. Edit the file and restart
# the container to change anything. The file needs a `default` group and at
# least one enabled upstream, or the container exits with code 2. A
# recreated nxdns-data volume rebuilds itself from the file on next start.
#
# Drop this line to let the database be the truth instead, and load a first
# configuration once with:
# docker compose run --rm nxdns import /etc/nxdns/config.zon
