Versioned DNS

This is a containerized DNS server that pulls the configuration from a Git repository. The container is based on dnsmasq, which uses a hosts file for generating DNS records. My use cases for this are:

• Providing memorable URLs for services running in a home VPN.
• Resolving web URLs for local development, such as *.dev.mydomain.priv.

Providing DNS records

There are two ways to provide DNS records:

1. Pass environment variable GIT_PATH containing the full path to the Git repository.
2. Mount a folder containing a file called hosts as /srv in the container.

Scripts

There are several lifetime scripts provided in the scripts directory:

• build - only build the container
• test - run the test setup
• start - start the container in the background without building
• stop - remove the container
• restart - stop, then start

Depending on your Docker setup, you might have to run them as sudo.
