post update hook for gitosis and jekyll

If you have a gitosis server on which you host blog using jekyll (that would be 0.00001% of the bloggers I guess ;) ). You can use the following file as a post-update hook to update your jekyll blog.

So, let’s say your git repository is named example.com, browse to /home/git/repositories/example.com/hooks and create a file with the name post-update, copy the content below to your post-update file. That’s it you are set, the next time you push to your git repo, your blog will be automatically published.

#post-update
unset GIT_DIR && cd /var/www/blogs/example.com && git pull && jekyll
#/var/www/blogs/example.com is where your blog's repo is cloned
echo "finished deployment"

Below are a couple of problems I ran into and how I fixed them:

  • File permissions issue cannot write to .git/FETCH_HEAD, you’ll get this error if the ‘git’ user doesn’t have write privileges to your blog’s cloned directory, you can fix it by giving write permissions to your git user to this directory
  • Permission to repo denied to username: this means your git user doesn’t have read priveleges on your repository. Fix it by giving the git user readonly privileges in your gitosis.conf

I am currently working on Zammu which makes Automatic Deployment of static websites to Github Pages very easy. I would love to get your feedback on it, Use the invitation code KHAJA
