dnsmasq is a lightweight DNS server. It is provides as docker image. Configuration file are provided via a mapped directory of .conf files.
Starting a container from this image is simple. We run it directly on the host's network stack so the host can act as a DNS for other services in the network.
docker run --name dnsmasq --cap-add=NET_ADMIN --net=host -v /etc/dnsmasq:/etc/dnsmasq dtjs48jkt/dnsmasq
You can use add multiple .conf files in the /etc/dnsmasq folder (e.g. for a layered configuration).
