# Controls when the action will run.

  # Triggers the workflow on push or pull request events but only for the master branch
  push:
    branches: [ main ]

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  # This workflow contains a single job called "build"
  build:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:       
    - name: Deploy using ssh
      uses: appleboy/ssh-action@master
      with:
        host: ${{ secrets.HOST }}
        username: ${{ secrets.USERNAME }}
        key: ${{ secrets.SSH_KEY }}
        port: 22
        run: |
          ssh $username@$host "
          cd /odoo/custom-addons/learnrepo &&

And click on commit changes in the top right corner.
