Connect a local git repo to google cloud VM

Question

I've been trying to link a local python flask repo to my remote (production) vm in the google cloud.

On Google VM :

sudo mkdir /home/git && cd /home/git
sudo mkdir flask_project.git && cd flask_project.git
sudo git init --bare

sudo vim hooks/post-receive
{Added}
#!/bin/sh
GIT_WORK_TREE=/home/www/flask_project git checkout -f

sudo chmod +x hooks/post-receive

On Local dev

git init
git remote add production web@<externalip>:/home/git/flask_project.git

I've generated SSH keys and added public key to GCP Metadata but when I push commits from local to remote :

git push production master

Git stalls and the commit doesn't reach remote.

Any ideas how I can link the repo's?

Answer 1

Your /home/git/flask_project.git bare repo is owned by root after the steps you executed.

But you're attempting to operate it as web (according to your remote production config), which doesn't have write permissions on the bare repo. I suspect that depending on the OS this may cause the hanging - on my older opensuse it just fails with:

remote: error: insufficient permission for adding an object to repository database objects

Try sudo chown -R web /home/git/flask_project.git

Alternatively, if you plan to push to that repo as multiple users (git comes to mind), you could use the git init --bare --shared to create the bare repo instead. Not a great practice, tho.

Side note: you also need to clone the repo in /home/www/flask_project (as web as well) before the hook can operate properly, otherwise you'll probably get something like:

remote: fatal: This operation must be run in a work tree
