chrisgavin/hostinator repository overview

⁠Hostinator

Hostinator is a tool for automatically adding Docker containers to the hosts file.

⁠Purpose

Docker Compose has a really useful feature that enables you to access a container by alias from within containers on the same network. The primary aim of this project is to make those same resolutions work from the Docker host.

⁠Features

• Detects new Docker containers dynamically by monitoring the Docker socket for events.
• Puts your hosts file back to how it was originally on exit.
• Limit Docker network to search for hosts with HOSTINATOR_NETWORK environment variable.

⁠Docker Image

This project is availiable as a Docker image at chrisgavin/hostinator⁠. You can use it like so:

docker run -it --rm \
	-v "/var/run/docker.sock:/var/run/docker.sock" \
	-v "/etc/:/mnt/etc/" \
	chrisgavin/hostinator

You can also integrate this with an existing Docker Compose configuration. You can add it as a service in your Docker Compose file.
