GitHub Actions can be used to do something whenever something happens in one of your GitHub repositories. If you are not familiar with GitHub Actions, check out my article Getting Started with GitHub Actions.

Let's say you create a file in your runner VM and you want to add and commit the file to your repo.

name: GitHub Action
run-name: ${{ github.workflow }} run by ${{ github.actor }}
on:
  push:
    branches:
      - main
jobs:
  github-action-job:
    runs-on: ubuntu-latest
    steps:      
      - name: Checking out the repository code
        uses: actions/checkout@v4

      - name: create foo.txt
        run: touch foo.txt
        
      - name: git config user.name
        run: git config user.name "github-actions"

      - name: git config user.email
        run: git config user.email "github-actions@example.com"        

      - name: git add foo.txt to repo
        run: git add foo.txt
        
      - name: git commit foo.txt
        run: git commit -m 'initial commit' foo.txt

      - name: git push origin HEAD
        run: git push origin HEAD
