A post-receive deployment hook for octopress repositories.

octopress-post-recieve-hook.md

Depends on:

• Octopress git repo
• tar
• rsync
• rake

Fill in the variables appropriately and copy to hooks/post-receive in your bare git repo

• git_branch: git branch which holds the source files for the live site
• file_bashrc: path to a ,bashrc (or really any bash file) which provides rbenv and adds a PATH directory containing rake
• dir_tmp: what directory to create a temporary copy of the $git_branch index inside of. THIS DIRECTORY WILL BE DESTROYED BY THE cleamTmp CALL AT THE END OF THE SCRIPT. It will also be automatically created if it does not yet exist.
• dir_src: The directory which Octopress compiles the static html files into. By default, the tree subdirectory 'public/'
• dir_live: Webroot directory

Copy configured script to hooks/post-receive in the bare repository on the remote end.

I've had an issue with the 'git archive | tar' command in checkoutBranch() method, not sure why.

I've updated this method in my fork using the git archive documentation.

Another note, use #/bin/bash -l with the -l argument.

I had issue loading rvm from $HOME/.bashrc without this argument.

Thanks a lot for your script :)
