Answer 1

This post on Seb Duggan blog describe it nicely. You simply create post-receive hook that contain:

#!/bin/sh
GIT_WORK_TREE=/path/to/webroot/of/mywebsite git checkout -f

Add it +x flag and it will checkout your repo in given folder.

Answer 2

Use rsync rather than cp for this operation. It does diff checking automatically. that way your post-commit hook doesn't become needlessly complicated.

Answer 3

You would need to add to the bare repo (managed by GitLab) a post-receive hook which would:

• maintain a working tree (git checkout -f master)
• copy the files you want from that working

That would be:

cd ~git/repositories/yourRepo.git/hooks
touch post-receive
chmod +x post-receive

You can make sure that hook will only be active if someone pushes on branch master:

#!/bin/bash
while read oldrev newrev refname
do
    branch=$(git rev-parse --symbolic --abbrev-ref $refname)
    if [ "master" == "$branch" ]; then
        # Do something
    fi
done

For the checkout done by that hook, see "GIT post-receive checkout without root folder", that is:
make sure you specify --git-dir and --git-work-tree:

git --git-dir=/path/to/project_root.git --work-tree=/path/to/your/workingtree checkout -f

Again, /path/to/your/workingtree can be:

• only an intermediate working tree for you to extract from it the relevant files you want to copy.
• or the path to your app, if you want all the files from master to be updated in the destination directory of your wab app.
