go-gitreceive

go-gitreceive is meant to handle the following tasks:

1. init - add the "git" user
2. upload-key - uploads SSH keys for users so they can push git repositories
3. run - runs a command and initializes the git repository if it doesn't exist
4. hook - runs a pre-receive hook in order to deploy an application

Purpose

It's meant to be a Go implementation of progrium/gitreceive which doesn't rely on bash and can integrate into third party systems and APIs.

It's currently a drop in replacement for the bash version of gitreceive.

Requirements

You need to have Go 1.1 installed to build this. You also need to have git and sshd installed for this tool to work.

git clone https://github.com/coreos/go-gitreceive.git
cd go-gitreceive
go build

Usage

Add the git system user:

This adds a system user called 'git' with a home directory /home/git.

$ sudo go-gitreceive init

Create an user

This uploads an SSH key from another system. You need to specify the username, too. The username specified at the end won't be a system user, but it'll be associated to your public key.

$ cat ~/.ssh/id_rsa.pub | ssh yoursystemuser@server "sudo go-gitreceive upload-key yourdesireduser"

Add a remote to an existing repository

This will add a remote to an existing repository. The remote repository will be created automatically the first time you push.

$ git remote add test git@server.com:testproject.git

Push

This will push to the remote git repository and create it. The example below is an example of what's displayed when using go-gitreceive with dokku to deploy a go web application.

The go-gitreceive binary has to be named gitreceive in order to work as drop in replacement to gitreceive.
