How to set up a Git hook so that after pushing to ssh://peter@foo.com/~/bar.com.git, it will go to ~/bar.com and do a git pull?

Question

I was advised to set up on a remote server

foo.com/~/bar.com       # live webpage content
foo.com/~/bar.com.git   # a bare repo

so, from my

Answer 1

I use the following post-update script (make sure you set executable bit on it):

#!/bin/sh
rm -rf ~/public_html/xxx
git-archive --format=tar --prefix=xxx master | tar x -C ~/public_html

It does the thing, but there's a short window when the site is not available. Doing git pull directly in yours ~/bar.com will expose git's .git directory, so make sure you either block it in your http server, or keep .git somewhere higher in directory hierarchy, ie. something like:

~
 \
  - repo
    \
     - .git
     - bar.com
       \
        - your content

Answer 2

You can add a post-receive hook to the ~/bar.com.git repo for this. To do this add to the ~/bar.com.git/hooks/ directory an executable file post-receive with the content:

#!/bin/sh

unset $(git rev-parse --local-env-vars)
cd ~/bar.com
git pull

Make sure the post-receive file has the executable bits(e.g. 755).

Now whenever something is pushed to the ~/bar.com.git repo, the ~/bar.com repo is updated automatically.
