This recipe is to describe the steps for taking a local folder that's managed by git and using a remote server where you have ssh access, creating an "as-simple-as-possible" remote that can be pushed to (and eventually pulled from) and that is also mirrored on the same server. In other words, there's also a public working directory that automatically gets updated (via a githook) when the repo is pushed to. This recipe does not require that you use a git server like gitea, gitlab, or github. Just that you have ssh access to a server, and that git (client) is installed there too. You can combine this with also using a git server (as git repos can have multiple remotes).

The steps

  • Convert local folder into a bare repo
  • scp the bare repo to a (non-public) part of your server
  • Create the webhook in the bare repo on the server

On you local computer

Convert local folder into a bare repo

   git clone --bare project project.git

Converts normal folder project (that is already git-managed!), into a bare repository project.git.

A bare repo is basically only the .git folder part of a git-managed folder (it's insides if you like). You could in principle just copy this (inner) folder, but git's clone command has a bare option that does it for you. It's a good idea to name a bare repo .git to remind yourself that it's a bare git repo.

scp the bare repo to your server

Here assuming you have a folder called git in your remote home folder.

   scp -r project.git sshuser@myvps.net:git/

or if you have configured a host alias in your .ssh/config (in this case called "myvps").

   scp -r project.git myvps:git/

Add the remote to your original repo

At this point you can delete the bare repo (it's now on the server). Let's add the ssh address of the repo on the server as the "myserver" remote. You can name the remote whatever you want including "origin" if you would like the remote server to use this, the default and most common remote name.

first

   cd project

then

   git add remote myserver sshuser@myvps.net:git/project.git

or

   git add remote myserver myvps:git/project.git

and finally

   git push --set-upstream myserver main

On the remote server

ssh to your server

   ssh sshuser@myvps.net

or again if you have an ssh host alias, you can just use it:

   ssh myvps

Clone the bare repo to a (public) working directory

   cd public_html
   git clone ~/git/project.git

Create the webhook

   cd ~/git/project.git

You can ls and see the "insides" of the repo:

   branches/  config  description  HEAD  hooks/  info/  objects/  packed-refs  refs/

Make sure there's not already a post-receive script...

   ls hooks

Ok, let's create one...

   nano git/project.git/hooks/post-receive
GIT_WORK_TREE=~/public_html/project git checkout -f⏎

Make the hook executable

   chmod +x ~/git/project.git/hooks/post-receive

Test it out (from your local machine)
