# App + dnsmasq in one container. Use this image for running dnsmasq (and the UI) in Docker.
|
|
# Both run as root; file permissions work because config dirs are in the container.
|
|
# For dnsmasq on the host, use the self-contained publish (scripts/publish-self-contained.sh)
|
|
# or run the app on the host; see DnsmasqOptions XML doc for permissions and ReloadCommand scope.
|
|
#
|
|
# Dnsmasq install mode for the test harness:
|
|
# - DNSMASQ_VERSION=latest (default): build the latest stable upstream dnsmasq release.
|
|
# - DNSMASQ_VERSION=<version> : build that exact upstream release (e.g. 2.91).
|
|
# - DNSMASQ_VERSION=distro : use the distro package from apt.
|
|
#
|
|
# This keeps day-to-day harness use close to upstream while still allowing pinned-version testing.
