How to automate git to automatically clone a repo on the server?


I have a repo in which I want to push changes. I want to sync two repositories: ./pages.git into ./pages. My git setup on my development machine pushes into pages.git. But the web-application works with ./pages.

git clone pages.git pages
fatal: destination path 'pages' already exists and is not an empty directory.

Well now I delete the pages directory and git clone works. But that's not the clean solution, isn't it?

Is there any way to do that without having to delete the pages directory manually? I'd like to automate that process so that git automatically performs the actions whenever I push.

Best, Marius


Solution

  • Why not just create a post-receive hook for the pages.git repository that will do a git pull from within the pages repository to pull over the changes? git clone is designed to be run only once per resulting clone (hence why it complains until you delete the previous clone), whereas git pull is designed to be run repeatedly whenever you want to update a repo with changes from another.

    I have a hook setup for something essentially the same as this with a particular repository, here's the gist of it:

    cd /var/repos/path_to_mirror || exit
    unset GIT_DIR
    git pull origin master
    
    • In this case, path_to_mirror is the equivalent of pages in your situation.
    • This script would be in the pages.git/.git/hooks/post-receive file.
