Azure app service connection string disappears on redeployment

Question

I add a connection string to my app service (configuration > connection strings > + New connection string > Save), and this works. But when I redeploy through my CI/CD github workflow, the connection string is gone.

Before a new deployment:

After a new deployement:

My workflow file:

on: [push]
name: workflow
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2 # checks-out your repository under $GITHUB_WORKSPACE, so your workflow can access it.
      - run: dotnet --version
      - run: dotnet tool restore
      - run: dotnet run --project tests/Server/Server.Tests.fsproj
  build-and-deploy:
    if: github.ref == 'refs/heads/deploy'
    needs: test
    runs-on: ubuntu-latest
    steps:
      - name: 'Checkout Github Action'
        uses: actions/checkout@v2

      - name: 'Login via Azure CLI'
        uses: azure/login@v1
        with:
          creds: ${{ secrets.AZURE_CREDENTIALS }}

      - name: 'Restore'
        run: dotnet tool restore

      - name: 'Deploy'
        run: dotnet run azure

Answer 1

I have deployed the .NET Core App to Azure App service using GitHub Actions.

• Added new Connection String in Configuration => Connection Strings as you have mentioned.

• When I tried to Sync (Redeploy) from Deployment Center, got the below alert.

• It clearly says that old deployment changes will be updated with the new one.

• But for me the Connection String is not missing.

• 创建应用程序服务时，最初 Disable GitHub Actions 设置。

• 稍后，从部署中心连接到GitHub。

• 如果我们不想错过部署后完成的任何configurations。不要使用Sync 选项重新部署应用程序，而是单击Disconnect

• 重新连接并再次构建工作流程。

• 可以看到可用的Connection Strings。
