git-cache

A docker image for caching git clone/pull based on jonasmalacofilho/git-cache-http-server, with

1. git compression level turned to 9.
2. git gc --aggressive run on every cached repository every night at 1:30 (can be overriden by environment variables HOUR and MIN, in 24 hour format).
3. After WAIT_TIMEOUT (default to 4 hours, can be overloaded by environment variables), no new git gc --aggressive process will be spawned. In the next day, gc process will start from where it was left.
4. The git gc process and the gc thread that account for monitoring and spawning git gc process is limited by:
   • nice set to 19
   • Using SCHED_BATCH scheduler.

NOTE:

The time inside container maybe is different from your host due to different timezone.

Usage

Pull from docker hub

Simply run docker pull nobodyxu/git-cache.

How to build

Just run make to build it.

Optionally, you can run the docker image from NobodyXu/apt-cache to enable apt-cache.

NOTE

The image will automatically test whether port 8000 on your machine is open, so if you run something else on 8000 that is not a squid-deb-proxy, run env NO_APT_PROXY=true make.

How to run

After building the image, type make run to run the container, which also creates a volume for storing cache and publish a port on 8080.

How to use

To use the cache, simply run

git config --global url."http://$HOST_IP:$PORT_NUMBER/".insteadOf https://

in the container or on other machines.
