How to connect hosting to GitLab and be able to edit hosting through GitLab?

Question

git

In short, my friend and I want to make a server in Garis, and for this we thought about how to make it so that I can go to GitLab or GitHub and start editing plugins on the server without access to the hosting, and then they are synchronized with the files on the hosting.
In short: how to synchronize files from a folder on github or GibLab via git and console in ubuntu. And it is possible to automate this process. And the ability to do both ways - that is, to synchronize files.

Answer 1

and if you mistakenly correct the file? site will fall.
it is better to link the develop branch to some test site (local or remote), make all changes there, test, then merge with the master branch. this will be stored on GitHub / GitLab, and from there you will need to download the changes from the master branch to the main site with the git pull command
