git-mirror - simple Git mirrors

git-mirror is designed to create and serve read-only mirrors of your Git repositories locally or wherever you choose. A recent GitHub outage reinforces the fact that developers shouldn't be relying on a single remote for hosting code.

A major design goal of git-mirror is that it should just work with as little configuration as possible.

Get started

Download and extract the latest release from the releases page.

Create config.toml similar to:

[[repo]]
Origin = "https://github.com/beefsack/git-mirror.git"

By default it will update the mirror every 1 minute and will serve the mirror over HTTP using port 8080. You can specify as many repos as you want by having multiple [[repo]] sections.

Run git-mirror with the path to the config file:

$ ./git-mirror config.toml
2015/05/07 11:08:06 starting web server on :8080
2015/05/07 11:08:06 updating github.com/beefsack/git-mirror.git
2015/05/07 11:08:08 updated github.com/beefsack/git-mirror.git

Now you can clone from your mirror on the default port of 8080:

$ git clone http://localhost:8080/github.com/beefsack/git-mirror.git
Cloning into 'git-mirror'...
Checking connectivity... done.

Using with docker

You can run it with docker:

docker run --rm -ti -v /your_config/path:/config  kumekay/git-mirror /config/config.toml

Or with docker compose, for example:

services:
  git-mirror:
    image: kumekay/git-mirror
    ports:
      - "8080:8080"
    command: ["/etc/git-mirror/config.toml"]
    volumes:
      - /opt/git-mirror/data:/git-mirror
      - /opt/git-mirror/config:/etc/git-mirror
    restart: always

Advanced configuration

See the example config for more advanced configurations.

Authentication and authorisation

If you wish to control access to the mirror or specific repositories, consider proxying to git-mirror using a web server such as Nginx.
