The Mysterious Case of AzureWebApp@1: Unraveling the Enigma of Deployment to site/wwwroot

If you’re reading this, chances are you’ve stumbled upon the frustrating issue of AzureWebApp@1 refusing to deploy to the site/wwwroot directory. Fear not, dear developer, for we’re about to embark on a journey to unravel the mystery behind this frustrating phenomenon.

The Symptoms: A Closer Look

Before we dive into the solution, let’s take a closer look at the symptoms. When AzureWebApp@1 fails to deploy to site/wwwroot, you might encounter the following issues:

• Your Azure DevOps pipeline runs successfully, but your web app remains unchanged.

• The deployment log indicates a successful deployment, but your files aren’t updated in the site/wwwroot directory.

• You’ve tried tweaking the pipeline, adjusting the configuration, and even performing a ritual dance around your computer, but nothing seems to work.

The Culprits: Understanding the AzureWebApp@1 Task

To tackle this issue, we need to understand how the AzureWebApp@1 task works. This task is responsible for deploying your web application to an Azure App Service. By default, it deploys to the `wwwroot` directory, but that’s not always the case.

steps:
- task: AzureWebApp@1
  displayName: 'Azure Web App Deploy'
  inputs:
    azureSubscription: $(azureSubscription)
    appName: $(appName)
    package: $(System.ArtifactsDirectory)/**/*.zip

In this example, the AzureWebApp@1 task is configured to deploy a zip package to the specified Azure App Service. However, the `package` input is where the magic happens. The `**/*.zip` pattern tells the task to look for zip files in the `System.ArtifactsDirectory` and deploy them to the app service.

The Solution: Unraveling the Enigma

Now that we’ve identified the culprits, let’s get to the solution. To deploy to the site/wwwroot directory using AzureWebApp@1, follow these steps:

1. Ensure your zip file is named correctly. The AzureWebApp@1 task expects the zip file to have the same name as the app service. For example, if your app service is named `mywebsite`, your zip file should be named `mywebsite.zip`.

2. Update the `package` input in your AzureWebApp@1 task to point to the correct zip file.

   steps:
   - task: AzureWebApp@1
     displayName: 'Azure Web App Deploy'
     inputs:
       azureSubscription: $(azureSubscription)
       appName: $(appName)
       package: $(System.ArtifactsDirectory)/mywebsite.zip
   

3. In your Azure App Service, navigate to the Configuration section and scroll down to the Path mappings section. Ensure the `site/wwwroot` directory is correctly configured.

   Virtual path	Physical path
   /	site/wwwroot

4. Save your changes and re-run your Azure DevOps pipeline. Your AzureWebApp@1 task should now deploy to the site/wwwroot directory.

Common Pitfalls and Workarounds

As you navigate the complexities of AzureWebApp@1, you might encounter some common pitfalls. Here are a few workarounds to keep in mind:

Issue: Multiple Zip Files

If you have multiple zip files in your artifacts directory, the AzureWebApp@1 task might get confused. To avoid this, use a more specific filename in the `package` input:

package: $(System.ArtifactsDirectory)/mywebsite-$(Build.BuildId).zip

Issue: Incorrect File Permissions

If your zip file contains files with incorrect permissions, the deployment might fail. To resolve this, ensure your zip file is created with the correct permissions. You can use the `ArchiveFiles` task to create a zip file with the correct permissions:

steps:
- task: ArchiveFiles@2
  displayName: 'Archive files'
  inputs:
    rootFolderOrFile: '$(System.DefaultWorkingDirectory)/mywebsite'
    includeRootFolder: false
    archiveFile: '$(System.ArtifactsDirectory)/mywebsite-$(Build.BuildId).zip'

Conclusion: Unraveling the Enigma of AzureWebApp@1

In conclusion, deploying to the site/wwwroot directory using AzureWebApp@1 requires a deep understanding of the task’s configuration and the Azure App Service’s path mappings. By following the steps outlined in this article, you should be able to resolve the issue and deploy your web application successfully.

Remember, the mysterious case of AzureWebApp@1 is not a myth; it’s a challenge waiting to be overcome. With patience, persistence, and a dash of creativity, you’ll be deploying to site/wwwroot in no time.
