How to deploy a GitHub private repository to shared hosting

I have seen many ways to deploy a GitHub repository to shared hosting (cPanel).

But there are so many ways, and they are not all the same, and the solutions are not especially clear to me.

Firstly, I want to know how to set it up so that the shared hosting will change automatically when we update a repository to be deployed.

Secondly, is it possible to manage it both manually and automatically for making changes (I prefer automatically, but I also want to know how to do it manually).

I think I understand what you are looking for. A good way of deploying your GitHub repository to CPanel is through GitHub Actions and an FTP connection.

Create a new action in your GitHub repository, which will prompt the creation of a main.yaml file which you can fill with the following code taken from https://github.com/marketplace/actions/ftp-deploy.

on: push
name: 🚀 Deploy website on push
jobs:
  web-deploy:
    name: 🎉 Deploy
    runs-on: ubuntu-latest
    steps:
    - name: 🚚 Get latest code
      uses: actions/checkout@v2
    
    - name: 📂 Sync files
      uses: SamKirkland/FTP-Deploy-Action@4.3.0
      with:
        server: ftp.samkirkland.com
        username: myFtpUserName
        password: ${{ secrets.ftp_password }}

Customize your server, username and password (preferably using repository secret variables) and every time there is a commit to the main branch, the files will be uploaded/modified in the FTP repository.
