Short Description
Dnsmasq, a simple and reliable DNS Server !
Full Description

Docker DNSMASQ

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.

Example in a docker-compose

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_ADMIN

Configuration Example

To 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.

#log all dns queries
log-queries
#dont use hosts nameservers
no-resolv
#use google as default nameservers
server=8.8.4.4
server=8.8.8.8
#explicitly define host-ip mappings
address=/router/10.1.1.1
address=/server/10.1.1.2
