Simple Laravel 4 deployment using git hooks and shell scripts

readme.md

On the server where your project should be deployed:

1. Create a bare repository somewhere all contributors have read/write access. git init --bare /path/to/project.git

2. git clone into the path where you want the project files to be cloned - for example, git clone /path/to/project.git /var/www/myproject.

Repeat step 2 if you want to have multiple setups - for example, one for production, one for staging.

3. Open /path/to/project.git/hooks/post-update in your favourite text editor and paste in the bash script above. Make sure to chmod +x the file.

On your local machine:

4. Initialize a repository for your project, add all the files you want commited, remember to chmod +x bin/install.bash and make sure the file permissions is reflected in the repository. Put the install.bash script in a bin directory in the project root and add it to the git repository - make sure its permissions are set to executable in the git repository as well.

5. git remote add server myuser@my.server.host:/path/to/project.git && git push server master

You should at this point see a bunch of messages from the remote indicating the progress of the deploy script. If nothing is happening, you probably forgot to chmod +x the post-update file. If you get any errors, debug and fix them.
