dnsmasq-webui/docker-compose.test.yml

# Run the app with real dnsmasq and a DHCP client so hosts/leases are real.
# Prepare mount: ./scripts/prepare-test-mount.sh [--prepare-only | --no-build | --recreate | --source DIR | --mount DIR]
# Or set TESTDATA_MOUNT to override the data volume (default: ./testdata-mount).
#
# app builds from Dockerfile.dnsmasq (app + dnsmasq in one container; app is main process).
# ReloadCommand/StatusCommand use pkill/pgrep (procps in image). cap_add NET_ADMIN for dnsmasq.
#
# Networks: testnet 172.28.0.0/16 so dnsmasq can hand out 172.28.0.10–50.
