docker-image-dns

This repository contains the Docker image that can be used to set up a local dns server. This DNS server will let you browse to containers by appending .docker to the container name in the browser.

This image is based on https://github.com/jderusse/docker-dns-gen

Usage

Configure the local DNS Masq by doing the following:

sudo vim /etc/NetworkManager/dnsmasq.d/01_docker

Enter the following text:

bind-interfaces
interface=lo
interface=docker0
server=/docker/127.0.0.1#54

Restart the NetworkManager:

sudo systemctl restart NetworkManager

Next start the container and make sure it always restarts:

docker run --detach --name dns \
  --restart always \
  --publish 54:53/udp \
  --volume /var/run/docker.sock:/var/run/docker.sock \
  chesszebra/dns -R

Alternatively, if you are running a more barebones linux without dnsmasq and NetworkManager this is probably the easiest way to get it working:

1. Skip the NetworkManager config since it does not apply.
2. Start the container instead with –publish 53:53/udp
3. Add 127.0.0.1 to /etc/resolv.conf
