A tool for creating a git user that creates respositories on the fly and let's you run scripts or hit HTTP endpoints when you push code to them.
Build your own Heroku. Push code anywhere.
It's just not a
post-receive hook. It's a powerful wrapper around
pre-receive giving you easy access to the code that was pushed while still being able to send output back to the git user.
You need a Linux server with
On your server, run:
$ curl https://raw.github.com/progrium/gitreceive/master/installer | bash
This will install
clone this repo and put
gitreceive wherever you want.
Set up a git user on the server
This automatically makes a user and home directory if it doesn't exist.
$ gitreceive init Created receiver script in /home/git for user 'git'.
You use a different user by setting
GITUSER=somethingelse in the
environment before using
Modify the receiver script
As an example receiver script, it will POST all the data to a RequestBin:
$ cat /home/git/receiver #!/bin/bash URL=http://requestb.in/rlh4znrl echo "----> Posting to $URL ..." curl \ -X 'POST' \ -F "repository=$1" \ -F "revision=$2" \ -F "username=$3" \ -F "fingerprint=$4" \ -F contents=@- \ --silent $URL
The username is just a name associated with a public key. The fingerprint of the key is sent so you can authenticate against the public key that you may have for that user.
The repo contents are streamed into
STDIN as an uncompressed archive (tar file). You can extract them into a directory on the server with a line like this in your receiver script:
mkdir -p /some/path && cat | tar -x -C /some/path
Create a user by uploading a public key from your laptop
We just pipe it into the
gitreceive upload-key command via SSH:
$ cat ~/.ssh/id_rsa.pub | ssh email@example.com "gitreceive upload-key progrium"
The username argument is just an arbitrary name associated with the key, mostly for use in your system for auth, etc.
Add a remote to a local repository
$ git remote add demo firstname.lastname@example.org:example.git
example.git will be created on the fly when you push.
$ git push demo master Counting objects: 5, done. Delta compression using up to 4 threads. Compressing objects: 100% (3/3), done. Writing objects: 100% (3/3), 332 bytes, done. Total 3 (delta 1), reused 0 (delta 0) remote: ----> Receiving progrium/gitreceive.git ... remote: ----> Posting to http://requestb.in/rlh4znrl ... remote: ok To git@gittest:progrium/gitreceive.git 59aa541..6eafb55 master -> master
The receiver script did not attempt to silence the output of curl, so the respones of "ok" from RequestBin is shown. Use this to your advantage! You can even use chunked-transfer encoding to stream back progress in realtime if you wanted to keep using HTTP. Alternatively, you can have the receiver script run any other script on the server.
You can use
gitreceive not only to trigger code on
git push, but to provide
feedback to the user and affect workflow. Use
- Deploy on any arbitrary platform
- Run your build/test system as a separate remote
- Integrate custom systems into your workflow
- Build your own Heroku
- Push code anywhere
This whole system is contained in a single bash script less than 100 lines long. Let's keep it simple, but I'm definitely open to contribution!
