I am running the dnsmasq in a docker container. The image is built for multiple architectures making it easy to switch from platform to another if the need arises. Dnsmasq configuration is on a docker volume, so the image itself does not have any stored configuration. My config is also stored encrypted in my private github repo, so I can easily access it. Docker volume with the config on a glusterfs would be a feasible solution as well.
