Git-based website deployment workflow

Question

On my server, I have two users, www-data (which is used by nginx) and git. The git user owns a repository that contains my website\'s code

Answer 1

I ended up making the public content owned by the git user, and readable by all. Then, I did the following to set up the hooks:

Assuming the repository is called mysite:

1. Create a detached work tree that will act as the webroot (as the user git)

   mkdir /var/www/mysite
   cd /path/to/repository/mysite.git
   git config core.worktree /var/www/mysite
   git config core.bare false
   git config receive.denycurrentbranch ignore
   

2. Add a post-receive hook that will update the website and set correct permissions for it

   touch hooks/post-receive
   chmod +x hooks/post-receive
   vim hooks/post-receive
   

   The post-receive script:

   #!/bin/sh
   git checkout -f
   chmod -R o+rX /var/www/mysite

Update: Here is a better solution.

Note: earlier versions of this howto depended on setting the git config variables core.worktree to the target directory, core.bare to false, and receive.denycurrentbranch to ignore. But these changes are not needed if you use GIT_WORK_TREE (which didn't work when I first wrote the howto), and the remote repository can remain bare.
