How to setup an automated git email notifier server

(1)

 sudo wget http://git.icir.org/git-notifier.git/blob_plain/refs/heads/master:/git-notifier -O /usr/share/git-core/contrib/hooks/git-notifier
chmod +x /usr/share/git-core/contrib/hooks/git-notifier

(2) Add ssh private key to your .shh folder so git operations dont ask for password. This will be automated.

(3) For each new repo, do this :

git clone ${url}

add this to .git/config
[hooks]
	mailinglist = mysuperemail@gmail.com
	showrev = "git show -C %s; echo"
	emailprefix = "[git]"
Like this :

echo -e "[hooks]\n\tmailinglist = mysuperemail@gmail.com\n\temailprefix = \"[git]\"" >> .git/config 


copy this file to .git/hooks/post-receive

#!/bin/sh
GIT_DIR=/home/dev/ems/.git
GIT_WORK_TREE=/home/dev/ems 
/usr/share/git-core/contrib/hooks/git-notifier

chmod ug+x .git/hooks/post-receive

(4) Add a cronjob to do this

  5  *  *  *  * dev cd /repo/dir; git pull; .git/hooks/post-receive

Troubleshooting

If you get during cronjob
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
