git-script

Turns an empty directory on a remote server into a git push deploy target. Once set up, running git push myserver main from your local machine automatically pulls the code into the server directory and updates the working tree.

What it does

On the given SSH host:

1. Creates the target directory (mkdir -p).
2. Runs git init inside it.
3. Uploads create-post-update-hook.sh, executes it, and cleans up. The hook:
   • Writes .git/hooks/post-update, which updates the working tree via git reset --hard HEAD after each push and auto-stashes any dirty changes.
   • Sets git config receive.denyCurrentBranch ignore so pushes to a non-bare repo are accepted.

Result: the remote directory behaves like a deploy-on-push git remote.

Requirements

pip install fabric

scp must also be available on your PATH (standard on macOS/Linux).

The target host must be defined in your SSH config (~/.ssh/config):

Host myserver
    HostName example.com
    User deploy
    IdentityFile ~/.ssh/id_ed25519

Usage

python main.py <host> <repo_path>

Examples:

python main.py myserver /var/www/myapp
python main.py staging /home/deploy/api

Each command:

• connects to the given host over SSH,
• creates the directory and initializes it as a git repo,
• installs the post-update hook.

Adding the remote locally

After the script runs, inside the project you want to deploy:

git remote add myserver ssh://deploy@example.com/var/www/myapp
git push myserver main

After the push, the code running in /var/www/myapp on the server is updated automatically.
