Dnsmasq is a lightweight, easy to configure, DNS forwarder and DHCP server. It is designed to provide DNS and optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines.
This fork add filter-aaaa to it.
Here is a docker-compose.yml file that run a local dns server using this image. You can adapt it for your own needs as you wish.
version: '2'
services:
dns:
restart: always
image: strm/dnsmasq
volumes:
- ./dnsmasq.conf:/etc/dnsmasq.conf
ports:
- "53:53/udp"
cap_add:
- NET_ADMINIs possible to deploy with ansible using this role to create a complete Debian buster setup with docker and everything else that you may need.
- hosts: all
vars:
hostname: "my_dns_server"
domain: "strm.sh"

capabilities:
- NET_ADMIN
roles:
- opsxcq.linux_serverTo be able to run the above example, you will need a configuration file. This is a very basic example that has two hosts, but it serve our purpose.
