jasoncodes/dns-gen repository overview

⁠Secure Docker DNS-gen (previously: Docker dns-gen)

Why I forked this repository: the container should be build regularly and for all local and running containers should be a DNS entry created. Not only for exposed one

dns-gen sets up a container running Dnsmasq and [docker-gen]. docker-gen generates a configuration for Dnsmasq and reloads it when containers are started and stopped.

By default it will provide thoses domain:

• container_name.docker
• container_name.network_name.docker
• docker-composer_service.docker-composer_project.docker
• docker-composer_service.docker-composer_project.network_name.docker

⁠How it works

The container dns-gen expose a standard dnsmasq service. It returns ip of known container and fallback to host's resolv.conf for other domains.

⁠Fork

The rest of the upstream README has been removed here, but can still be found at the upstream repository⁠.

This fork does only one:

• For EVERY (its not important if it is public or not) container it creates an dnsmasq entry and removed it when the container die.

Nothing more.

⁠Running

To start the container, a command like the following can be used. Additionally, --restart always can be added to have the container start automatically when your machine is restarted.

docker run -d --name dns-gen -v /var/run/docker.sock:/var/run/docker.sock 8ear/secure-dns-gen

All other commands etc. you can read from the upstream repository⁠.
