dnsmasq in a docker container, configurable via a simple web UI

1. Create a /opt/dnsmasq.conf file on the Docker host

   # dnsmasq config, for a complete example, see: http://oss.segetech.com/intra/srv/dnsmasq.conf
   # log all dns queries
   log-queries
   # dont use hosts nameservers
   no-resolv
   # use cloudflare as default nameservers, prefer 1^4
   server=1.0.0.1
   server=1.1.1.1
   strict-order
   # serve all .company queries using a specific nameserver
   server=/company/10.0.0.1
   # explicitly define host-ip mappings
   address=/myhost.company/10.0.0.2

2. Run the container

   $ docker run \
   	--name dnsmasq \
   	-d \
   	-p 53:53/udp \
   	-p 8053:8080 \
   	-v /opt/dnsmasq.conf:/etc/dnsmasq.conf \
   	--log-opt "max-size=100m" \
   	-e "HTTP_USER=foo" \
   	-e "HTTP_PASS=bar" \
   	--restart always \
   	xuqingkuang/dnsmasq
   

3. Visit http://<docker-host>:8053, authenticate with foo/bar and you should see

   

4. Test it out with

   $ host myhost.company <docker-host>
   Using domain server:
   Name: <docker-host>
   Address: <docker-host>#53
   Aliases:
   
   myhost.company has address 10.0.0.2
   

Follow the guide - https://docs.docker.com/build/building/multi-platform/ or execut the command:

docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 -t <username>/<image>:latest --push .
