Deploy to DigitalOcean with git bare repo hooks

apt-get install git-core

Second, change to your home directory and create a new "bare repository" to deploy to.
cd ~/
mkdir repos && cd repos
mkdir awesomeblog.git && cd awesomeblog.git
git init --bare

Following that, we need to set up a post-receive hook. This is a shell script that Git runs when files are pushed to a repository. Create it like so:

cd hooks
touch post-receive
nano post-receive

Now paste in the following script, adjusting the variables accordingly. GIT_REPO is the path to the bare repository created in the previous step, TMP_GIT_CLONE is a location where the script will check out the files to and build the blog before copying them to /var/www. PUBLIC_WWW is the path where the final site will reside. In this example (assuming your web root is /var/www) the site would appear at http://example.org/awesomeblog, whereas it would appear at http://example.org if PUBLIC_WWW read /var/www instead.

#!/bin/bash -l
GIT_REPO=$HOME/repos/awesomeblog.git
TMP_GIT_CLONE=$HOME/tmp/git/awesomeblog
PUBLIC_WWW=/var/www/awesomeblog

git clone $GIT_REPO $TMP_GIT_CLONE
jekyll build --source $TMP_GIT_CLONE --destination $PUBLIC_WWW
rm -Rf $TMP_GIT_CLONE
exit
Save the file by pressing control+O and hitting the enter key. Then give the file executable permissions.

chmod +x post-receive


Add a Git Remote
Back on your local machine, add a remote to your blog's Git repository.

git remote add droplet user@example.org:repos/awesomeblog.git
Now you should be able to push your latest commits to the server with the following command:

git push droplet master
Any time you make a new blog post in Jekyll, commit the changes to the Git repository and push to your VPS. The cloud server will build the site and the changes will go live within seconds.

thanks, is really helpful
