• For example, we can have Stop Azure App Service workflow which runs every midnight (UTC+7) and Start Azure App Service workflow which runs at 6AM everyday (UTC+7).
• Follow this instruction to get Azure Credentials.

Example workflow to stop Azure App Service

# .github/workflows/stop-azure-app-service.yml
name: Stop Azure App Service
on:
  schedule:
    - cron: "0 17 * * *" # every midnight of UTC+7
jobs:
  stop_azure_app_service:
    name: Stop Azure App Service
    # Find more virtual environment at https://github.com/actions/virtual-environments#available-environments.
    runs-on: ubuntu-latest
    steps:
      - name: Azure Login
        # https://github.com/Azure/login/tags
        uses: azure/login@v1
        with:
          # We don't need to set a default subscription because we get credentials from a specific subscription.
          creds: ${{ secrets.AZURE_CREDENTIALS }} #
      - name: Stop Azure App Service with Azure CLI
        run: az webapp stop --name ${{ secrets.AZURE_APP_SERVICE_NAME }} --resource-group ${{ secrets.AZURE_RESOURCE_GROUP_NAME }}

Example workflow to start Azure App Service

# .github/workflows/start-azure-app-service.yml
name: Start Azure App Service

  schedule:
    - cron: "0 23 * * *" # every 6AM of UTC+7
jobs:
  start_azure_app_service:
    name: Start Azure App Service
    # Find more virtual environment at https://github.com/actions/virtual-environments#available-environments.

        with:
          # We don't need to set a default subscription because we get credentials from a specific subscription.
          creds: ${{ secrets.AZURE_CREDENTIALS }} #
      - name: Start Azure App Service with Azure CLI
