Deploy to App Service using GitHub Actions

Workflow file overview

A workflow is defined by a YAML (.yml) file in the /.github/workflows/ path in your repository. This definition contains the various steps and parameters that make up the workflow.

The file has three sections:

Use the Deployment Center

You can quickly get started with GitHub Actions by using the App Service Deployment Center. This will automatically generate a workflow file based on your application stack and commit it to your GitHub repository in the correct directory.

1. Navigate to your webapp in the Azure portal
2. On the left side, click Deployment Center
3. Under Continuous Deployment (CI / CD), select GitHub
4. Next, select GitHub Actions
5. Use the dropdowns to select your GitHub repository, branch, and application stack

• If the selected branch is protected, you can still continue to add the workflow file. Be sure to review your branch protections before continuing.

6. On the final screen, you can review your selections and preview the workflow file that will be  committed to the repository. If the selections are correct, click Finish

This will commit the workflow file to the repository. The workflow to build and deploy your app will start immediately.

The following examples show how to set up the environment for the different supported languages:

.NET

YAML

    - name: Setup Dotnet 3.3.x
      uses: actions/setup-dotnet@v1
      with:
        dotnet-version: '3.3.x'

ASP.NET

YAML

    - name: Install Nuget
      uses: nuget/setup-nuget@v1
      with:
        nuget-version: ${{ env.NUGET_VERSION}}

Deploy to App Service

To deploy your code to an App Service app, use the azure/webapps-deploy@v2 action. This action has four parameters:

Parameter                                     Explanation

• app-name:         (Required) Name of the App Service app
• publish-profile: (Optional) Publish profile file contents with Web Deploy secrets
• package:                (Optional) Path to package or folder. The path can include *.zip, *.war, *.jar, or a folder to deploy.
• slot-name:         (Optional) Enter an existing slot other than the production slot

.NET Core

Build and deploy a .NET Core app to Azure using an Azure publish profile. The publish-profile input references the AZURE_WEBAPP_PUBLISH_PROFILE secret that you created earlier.

YAML

name: .NET Core CI

on: [push]

env:

  AZURE_WEBAPP_NAME: my-app-name    # set this to your application's name

  AZURE_WEBAPP_PACKAGE_PATH: '.'      # set this to the path to your web app project, defaults to the repository root

  DOTNET_VERSION: '3.1.x'           # set this to the dot net version to use

jobs:

  build:

    runs-on: ubuntu-latest

    steps:

      # Checkout the repo

      - uses: actions/checkout@main

      

      # Setup .NET Core SDK

      - name: Setup .NET Core

        uses: actions/setup-dotnet@v1

        with:

          dotnet-version: ${{ env.DOTNET_VERSION }} 

      

      # Run dotnet build and publish

      - name: dotnet build and publish

        run: |

          dotnet restore

          dotnet build --configuration Release

          dotnet publish -c Release --property:PublishDir='${{ env.AZURE_WEBAPP_PACKAGE_PATH }}/myapp' 

          

      # Deploy to Azure Web apps

      - name: 'Run Azure webapp deploy action using publish profile credentials'

        uses: azure/webapps-deploy@v2

        with: 

          app-name: ${{ env.AZURE_WEBAPP_NAME }} # Replace with your app name

          publish-profile: ${{ secrets.AZURE_WEBAPP_PUBLISH_PROFILE  }} # Define secret variable in repository settings as per action documentation

          package: '${{ env.AZURE_WEBAPP_PACKAGE_PATH }}/myapp'

ASP.NET

Build and deploy an ASP.NET MVC app that uses NuGet and publish-profile for authentication.

YAML

name: Deploy ASP.NET MVC App deploy to Azure Web App

on: [push]

env:

  AZURE_WEBAPP_NAME: my-app    # set this to your application's name

  AZURE_WEBAPP_PACKAGE_PATH: '.'      # set this to the path to your web app project, defaults to the repository root

  NUGET_VERSION: '5.3.x'           # set this to the dot net version to use

jobs:

  build-and-deploy:

    runs-on: windows-latest

    steps:

    - uses: actions/checkout@main  

    

    - name: Install Nuget

      uses: nuget/setup-nuget@v1

      with:

        nuget-version: ${{ env.NUGET_VERSION}}

    - name: NuGet to restore dependencies as well as project-specific tools that are specified in the project file

      run: nuget restore

  

    - name: Add msbuild to PATH

      uses: microsoft/setup-msbuild@v1.0.2

    - name: Run MSBuild

      run: msbuild .\SampleWebApplication.sln

       

    - name: 'Run Azure webapp deploy action using publish profile credentials'

      uses: azure/webapps-deploy@v2

      with: 

        app-name: ${{ env.AZURE_WEBAPP_NAME }} # Replace with your app name

        publish-profile: ${{ secrets.AZURE_WEBAPP_PUBLISH_PROFILE  }} # Define secret variable in repository settings as per action documentation

        package: '${{ env.AZURE_WEBAPP_PACKAGE_PATH }}/SampleWebApplication/'
