Enable GitHub developers to deploy to Azure WebApps using GitHub Actions

GitHub Action for deploying to Azure Web App

With the Azure App Service Actions for GitHub, you can automate your workflow to deploy Azure Web Apps using GitHub Actions.

Get started today with a free Azure account!

This repository contains GitHub Action for Azure WebApp to deploy to an Azure WebApp (Windows or Linux). Supports deploying *.jar, *.war, *.zip or a folder.

If you are looking for a Github Action to deploy your customized image into an Azure Webapps container, consider using webapps-container-deploy action.

The definition of this Github Action is in action.yml.

End-to-End Sample Workflows

Dependencies on other Github Actions

• Checkout Checkout your Git repository content into Github Actions agent.
• Authenticate using Azure Web App Publish Profile or using Azure Login
• Environment setup actions
  • Setup DotNet Sets up a dotnet environment by optionally downloading and caching a version of dotnet by SDK version and adding to PATH .
  • Setup Node sets up a node environment by optionally downloading and caching a version of node - npm by version spec and add to PATH
  • Setup Python sets up Python environment by optionally installing a version of python and adding to PATH.
  • Setup Java sets up Java app environment optionally downloading and caching a version of java by version and adding to PATH. Downloads from Azul's Zulu distribution.

Create Azure Web App and deploy using GitHub Actions

1. Follow the tutorial Azure Web Apps Quickstart
2. Pick a template from the following table depends on your Azure web app runtime and place the template to .github/workflows/ in your project repository.
3. Change app-name to your Web app name.
4. Commit and push your project to GitHub repository, you should see a new GitHub Action initiated in Actions tab.

Runtime	Template
DotNet	dotnet.yml
Node	node.yml
Java	java_jar.yml
Java	java_war.yml
Python	python.yml

Sample workflow to build and deploy a Node.js Web app to Azure using publish profile

# File: .github/workflows/workflow.yml

on: push

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    steps:
    # checkout the repo
    - name: 'Checkout Github Action' 
      uses: actions/checkout@master
    
    - name: Setup Node 10.x
      uses: actions/setup-node@v1
      with:
        node-version: '10.x'
    - name: 'npm install, build, and test'
      run: |
        npm install
        npm run build --if-present
        npm run test --if-present
       
    - name: 'Run Azure webapp deploy action using publish profile credentials'
      uses: azure/webapps-deploy@v1
      with: 
        app-name: node-rn
        publish-profile: ${{ secrets.azureWebAppPublishProfile }}
        

Configure deployment credentials:

For any credentials like Azure Service Principal, Publish Profile etc add them as secrets in the GitHub repository and then use them in the workflow.

The above example uses app-level credentials i.e., publish profile file for deployment.

Follow the steps to configure the secret:

• Download the publish profile for the WebApp from the portal (Get Publish profile option)
• Define a new secret under your repository settings, Add secret menu
• Paste the contents for the downloaded publish profile file into the secret's value field
• Now in the workflow file in your branch: .github/workflows/workflow.yml replace the secret for the input publish-profile: of the deploy Azure WebApp action (Refer to the example above)

Sample workflow to build and deploy a Node.js app to Azure WebApp using Azure service principal

• Azure Login Login with your Azure credentials for Web app deployment authentication. Once login is done, the next set of Azure actions in the workflow can re-use the same session within the job.

on: [push]

name: Node.js

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    steps:
    # checkout the repo
    - name: 'Checkout Github Action' 
      uses: actions/checkout@master
   
    - uses: azure/actions/login@v1
      with:
        creds: ${{ secrets.AZURE_CREDENTIALS }}
        
    - name: Setup Node 10.x
      uses: actions/setup-node@v1
      with:
        node-version: '10.x'
    
    - name: 'npm install, build, and test'
      run: |
        npm install
        npm run build --if-present
        npm run test --if-present
               
    # deploy web app using Azure credentials
    - uses: azure/webapps-deploy@v1
      with:
        app-name: 'node-rn'

    # Azure logout 
    - name: logout
      run: |
        az logout

Configure deployment credentials:

For any credentials like Azure Service Principal, Publish Profile etc add them as secrets in the GitHub repository and then use them in the workflow.

The above example uses user-level credentials i.e., Azure Service Principal for deployment.

Follow the steps to configure the secret:

• Define a new secret under your repository settings, Add secret menu
• Paste the contents of the below az cli command as the value of secret variable, for example 'AZURE_CREDENTIALS'

   az ad sp create-for-rbac --name "myApp" --role contributor \
                            --scopes /subscriptions/{subscription-id}/resourceGroups/{resource-group} \
                            --sdk-auth
                            
  # Replace {subscription-id}, {resource-group} with the subscription, resource group details of the WebApp
  
  # The command should output a JSON object similar to this:

  {
    "clientId": "<GUID>",
    "clientSecret": "<GUID>",
    "subscriptionId": "<GUID>",
    "tenantId": "<GUID>",
    (...)
  }
  

• You can further scope down the Azure Credentials to the Web App using scope attribute. For example,

 az ad sp create-for-rbac --name "myApp" --role contributor \
                          --scopes /subscriptions/{subscription-id}/resourceGroups/{resource-group}/providers/Microsoft.Web/sites/{app-name} \
                          --sdk-auth

# Replace {subscription-id}, {resource-group}, and {app-name} with the names of your subscription, resource group, and Azure Web App.

• Now in the workflow file in your branch: .github/workflows/workflow.yml replace the secret in Azure login action with your secret (Refer to the example above)
