Get started today with a free Azure account!

This repository contains GitHub Action for Azure App Service Settings to configure App settings, connection strings and other general settings in bulk using JSON syntax on your Azure WebApp (Windows or Linux) or any of its deployment slots.

The action works for ASP.NET, ASP.NET Core, PHP, Java, Python, Go and Node.js based web applications.

If you are looking for a Github Actions to deploy code or a customized image into an Azure Webapp, consider using WebApps-deploy action.

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

• Authenticate using Azure Login

Create Azure Web App and deploy using GitHub Actions

1. Follow the tutorial Azure Web Apps Quickstart
2. Pick a template from https://github.com/Azure/actions-workflow-samples depending 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.

Configure GitHub Secrets with Azure Credentials, App Settings and Connection Strings

For using any sensitive data/secrets like Azure Service Principal, App Settings or Connection Strings within an Action, add them as secrets in the GitHub repository and then use them in the workflow. If you do not have sensitive information in the app-settings -json and connection-strings-json and do not want to set it as secret, set mask-inputs as false in the workflow. By default, mask-inputs will be true. If mask-inputs: false is not provided, app-settings-json and connection-strings-json will be set as secrets and masked in logs. mask-inputs is not applicable to general-settings-json.

Follow the steps to configure the secrets:

• Define a new secret under your repository Settings > Secrets > Add a new 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 {app-name} --role contributor \
                            --scopes /subscriptions/{subscription-id}/resourceGroups/{resource-group} \
                            --sdk-auth
                            
  # Replace {subscription-id}, {resource-group} and {app-name} with the subscription, resource group and name of the WebApp
  
  # The command should output a JSON object similar to this:

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

• In the Azure portal, navigate to your app's management page. In the app's left menu, click Configuration > Application settings. To add or edit app settings in bulk, click the Advanced edit button. You could copy the existing App settings and make necessary changes or create a JSON object of the following format and define a new secret variable (APP_SETTINGS):

[
  {
    "name": "<key-1>",
    "value": "<value-1>",
    "slotSetting": false
  },
  {
    "name": "<key-2>",
    "value": "<value-2>",
    "slotSetting": false
  },
  ...
]

• In the Azure portal, navigate to your app's management page. In the app's left menu, click Configuration > Application settings > Connection Strings. To add or edit connection strings in bulk, click the Advanced edit button. You could copy the existing App settings and make necessary changes or create a JSON object of the following format and define a new secret variable (CONNECTION_STRINGS):

[
  {
    "name": "name-1",
    "value": "conn-string-1",
    "type": "SQLServer",
    "slotSetting": false
  },
  {
    "name": "name-2",
    "value": "conn-string-2",
    "type": "PostgreSQL",
    "slotSetting": false
  },
  ...
]

Sample workflow to configure settings on an Azure Web App

# .github/workflows/configureAppSettings.yml
on: [push]

jobs:
  build:
    runs-on: windows-latest
    steps:
    - uses: azure/login@v1
      with:
        creds: '${{ secrets.AZURE_CREDENTIALS }}'
    - uses: azure/appservice-settings@v1
      with:
        app-name: 'my-app'
        slot-name: 'staging'  # Optional and needed only if the settings have to be configured on the specific deployment slot
        app-settings-json: '${{ secrets.APP_SETTINGS }}' 
        connection-strings-json: '${{ secrets.CONNECTION_STRINGS }}'
        general-settings-json: '{"alwaysOn": "false", "webSocketsEnabled": "true"}' #'General configuration settings as Key Value pairs'
      id: settings
    - run: echo "The webapp-url is ${{ steps.settings.outputs.webapp-url }}"
    - run: |
        az logout

Sample workflow to configure settings on an Azure Web App when inputs need not be masked

# .github/workflows/configureAppSettings.yml
on: [push]

jobs:
  build:
    runs-on: windows-latest
    steps:
    - uses: azure/login@v1
      with:
        creds: '${{ secrets.AZURE_CREDENTIALS }}'
    - uses: azure/appservice-settings@v1
      with:
        app-name: 'my-app'
        mask-inputs: false
        slot-name: 'staging'  # Optional and needed only if the settings have to be configured on the specific deployment slot
        app-settings-json: '[{ "name": "SCM_DO_BUILD_DURING_DEPLOYMENT", "value": "1", "slotSetting": false }]'
      id: settings
    - run: echo "The webapp-url is ${{ steps.settings.outputs.webapp-url }}"
    - run: |
        az logout

Azure App Service Settings Action is supported for the Azure public cloud as well as Azure government clouds ('AzureUSGovernment' or 'AzureChinaCloud') and Azure Stack ('AzureStack') Hub. Before running this action, login to the respective Azure Cloud using Azure Login by setting appropriate value for the environment parameter.
