Troubleshoot of "az functionapp deployment source config-zip" in github actions

Question

I have a simple azure function app that I want to deploy via github pages, I'm trying to do it via: az functionapp deployment source config-zip. This works well from my local windows machine:

 C:\%APP_DEMO%>az functionapp deployment source config-zip -g WebApiDemoResourceGroup -n FunctionAppInstance1 --src functionapp.zip

but when I do it on github action like:

  buildFunction:
    runs-on: windows-latest
    needs: prepareAzure
    steps:
    - uses: actions/checkout@v3
    - name: Setup .NET SDK
      uses: actions/setup-dotnet@v3
      with:
        dotnet-version: ${{ env.DOTNET_CORE_VERSION }}
    - name: Restore
      run: dotnet restore "${{ env.FUNCTION_WORKING_DIRECTORY }}"
    - name: Build
      run: dotnet build "${{ env.FUNCTION_WORKING_DIRECTORY }}" --configuration ${{ env.CONFIGURATION }} --no-restore
    - name: Publish
      run: dotnet publish "${{ env.FUNCTION_WORKING_DIRECTORY }}" --configuration ${{ env.CONFIGURATION }} --no-build --output "${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}"
    - name: Publish Artifacts
      uses: actions/upload-artifact@v3
      with:
        name: functionapp
        path: ${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}

  deployFunction:
    runs-on: windows-latest
    needs: buildFunction
    steps:
    - name: Download artifact from build job
      uses: actions/download-artifact@v3
      with:
        name: functionapp
        path: ${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}
    - name: Azure Login
      uses: azure/CLI@v1
      with:
        azcliversion: 2.47.0
        inlineScript: |
          az login --service-principal \
          -u ${{ secrets.DEPLOYMENT_AZURE_CLIENT_ID }} \
          -p ${{ secrets.DEPLOYMENT_AZURE_CLIENT_SECRET }} \
          -t ${{ secrets.DEPLOYMENT_AZURE_TENANT_ID }}        
    - name: Deploy to Azure Function
      uses: azure/CLI@v1
      with:
        azcliversion: 2.47.0
        inlineScript: |
          zip -r functionapp.zip .
          groupName=${{ env.AZURE_GROUP_NAME }}
          az functionapp deployment source config-zip -g $groupName -n ${{env.AZURE_FUNCTION_NAME}} --src functionapp.zip

I see that deployFunction step is not failed, but in logs I see:

Run azure/CLI@v1
  with:
    azcliversion: 2.47.0
    inlineScript: zip -r functionapp.zip .
  groupName=%MyRG%
  az functionapp deployment source config-zip -g $groupName -n %APP_NAME% --src functionapp.zip
  
  env:
    AZURE_GROUP_NAME: %MyRG%
    AZURE_LOCATION: southcentralus
    AZURE_WEBAPP_NAME: WebApiDemoWebApp
    AZURE_WEBAPP_PACKAGE_PATH: WebApiDemo/publish
    CONFIGURATION: Release
    DOTNET_CORE_VERSION: 6.0.x
    WORKING_DIRECTORY: WebApiDemo
    FUNCTION_WORKING_DIRECTORY: %APP_DEMO%
    AZURE_FUNCTION_NAME: %APP_NAME%
    AZURE_FUNCTIONAPP_PACKAGE_PATH: %APP_DEMO%/published
Error: Please use Linux based OS as a runner.
Warning: Error: EPERM: operation not permitted, unlink 'D:\a\_temp'
cleaning up container...

how can I troubleshoot it? Even though the whole step is not failed, I don't see my deployed function on the portal.

Operating system I used for my fuction is Windows. I see it in the portal overview page:

Operating System
Windows

same I see in service plan:

Operating System
:
Windows

It might be related to this guard, but I have no ideas what it does mean.

Answer 1

I have azure function and web app in my resource group, if I switch azure function to linux, I see this error when I create web app (even before creating fuction): "message":"Linux dynamic workers are not available in resource group WebApiDemoResourceGroup. Use this link to. Something weird is going on..

I found few similar cases where in users facing the same issue. This seems to be a limitation.

1. Issue 1
2. Issue 2

• Create a new resource group and try to create linux function app in that particular resource group in a different region.

• Try to deploy your function app using GitHub-actions:

• As, @Azeem mentioned, change runs-on:windows to runs-on:ubuntu in your workflow and deploy.

 buildFunction:
    runs-on: ubuntu-latest
    needs: prepareAzure
    steps:
    - uses: actions/checkout@v3
    - name: Setup .NET SDK
      uses: actions/setup-dotnet@v3
      with:
        dotnet-version: ${{ env.DOTNET_CORE_VERSION }}
    - name: Restore
      run: dotnet restore "${{ env.FUNCTION_WORKING_DIRECTORY }}"
    - name: Build
      run: dotnet build "${{ env.FUNCTION_WORKING_DIRECTORY }}" --configuration ${{ env.CONFIGURATION }} --no-restore
    - name: Publish
      run: dotnet publish "${{ env.FUNCTION_WORKING_DIRECTORY }}" --configuration ${{ env.CONFIGURATION }} --no-build --output "${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}"
    - name: Publish Artifacts
      uses: actions/upload-artifact@v3
      with:
        name: functionapp
        path: ${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}

  deployFunction:
    runs-on: ubuntu-latest
    needs: buildFunction
    steps:
    - name: Download artifact from build job
      uses: actions/download-artifact@v3
      with:
        name: functionapp
        path: ${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}
    - name: Azure Login
      uses: azure/CLI@v1
      with:
        azcliversion: 2.47.0
        inlineScript: |
          az login --service-principal \
          -u ${{ secrets.DEPLOYMENT_AZURE_CLIENT_ID }} \
          -p ${{ secrets.DEPLOYMENT_AZURE_CLIENT_SECRET }} \
          -t ${{ secrets.DEPLOYMENT_AZURE_TENANT_ID }}        
    - name: Deploy to Azure Function
      uses: azure/CLI@v1
      with:
        azcliversion: 2.47.0
        inlineScript: |
          zip -r functionapp.zip .
          groupName=${{ env.AZURE_GROUP_NAME }}
          az functionapp deployment source config-zip -g $groupName -n ${{env.AZURE_FUNCTION_NAME}} --src functionapp.zip

Alternative:

As you are facing issue while creating linux function app, you can try other way to deploy the function to windows function app.

• Deploy via deployment center through Azure portal using GitHub actions. By this way, you can deploy your function app as zip package.

Go to your function app in Azure portal=>Deployment=>Deployment center=> Settings=>

• Select GitHub as source and provide the details of all other fields and save.

• Once you click on save, it starts the deployment.

• To check the deployment status, click on main=>It will be redirected to github=>click on Actions.

As shown below, GitHub actions deploys the function app using zip deployment.
