How to Copy a Folder from a TEST App Service to a LIVE App Service on Azure

问题

In my Azure DevOps Pipeline I would like to copy a folder e.g. Media from 1 environment/app service, say TEST to another environment/app service say Live. The Media folder in TEST may get updated AFTER the Ci/cd build has been deployed to the TEST environment - just to exclude answers that might suggest putting it in Git and including it as a Build artifact.

EDIT - Clarification on using the accepted answer.

My repo contains the given powershell script in the accepted answer as :

azure/Copy-Media-Test-To-Live.ps1

I then add the azure folder as an artifact in the build pipeline i.e.

Edit azure-pipelines.yml and Add:

- task: PublishPipelineArtifact@1 inputs: path: $(System.DefaultWorkingDirectory)/azure/ artifact: azure

In the release pipeline - reference the script to perform the copy:

steps: - task: AzurePowerShell@4 displayName: 'Azure PowerShell script: FilePath' inputs: azureSubscription: 'Your subscription ' ScriptPath: '$(System.DefaultWorkingDirectory)/_your-artifact-path/azure/Copy-Media-Test-To-Live.ps1' azurePowerShellVersion: LatestVersion

Any application running in an App Service Environment can be managed via Kudu. Kudu has an API for downloading a ZIP compressed archive of any folder currently deployed to an application. It can be accessed with a GET request to:

https://{{YOUR-APP-NAME}}.scm.azurewebsites.net/api/zip/site/{{FOLDER}}

You can use the Invoke-WebRequest cmdlet in PowerShell to pull this content to local storage.

You do need to authenticate to use the Kudu API, which is easy in a browser, but when automating is a little more involved. Please see the following article which details how to retrieve and present a Basic Authorization header, as well as demonstrating how to use the command API to extract a ZIP file using the Invoke-RestMethod cmdlet. Your service principal will need at least contributor access to your applications to get deployment credentials to use in the API calls.

EDIT (Include worked example script):

If you have multiple subscriptions and the context has not been set properly in the deployment runtime environment, you may need to use Set-AzContext -Subscription "<SubsciptionName>" to set the context for getting the WebApp

$srcResGroupName = "Test"
$srcWebAppName = "tstest12"
$srcDirectory = "/site/wwwroot/myFolder/"

$dstResGroupName = "Test"
$dstWebAppName = "tstest123"
$dstDirectory = "/site/wwwroot/myFolder/"

# Get publishing profile for SOURCE application

$srcWebApp = Get-AzWebApp -Name $srcWebAppName -ResourceGroupName $srcResGroupName
[xml]$publishingProfile = Get-AzWebAppPublishingProfile -WebApp $srcWebApp

# Create Base64 authorization header

$username = $publishingProfile.publishData.publishProfile[0].userName
$password = $publishingProfile.publishData.publishProfile[0].userPWD
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $username,$password)))

$apiBaseUrl = "https://$($srcWebApp.Name).scm.azurewebsites.net/api"

# Download the ZIP file to ./tmp.zip

Invoke-RestMethod -Uri "$apiBaseUrl/zip$($srcDirectory)" `
                    -Headers @{UserAgent="powershell/1.0"; `
                     Authorization=("Basic {0}" -f $base64AuthInfo)} `
                    -Method GET `
                    -OutFile ./tmp.zip

# Get publishing profile for DESTINATION application

$dstWebApp = Get-AzWebApp -Name $dstWebAppName -ResourceGroupName $dstResGroupName
[xml]$publishingProfile = Get-AzWebAppPublishingProfile -WebApp $dstWebApp

# Create Base64 authorization header

$username = $publishingProfile.publishData.publishProfile[0].userName
$password = $publishingProfile.publishData.publishProfile[0].userPWD
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $username,$password)))

$apiBaseUrl = "https://$($dstWebApp.Name).scm.azurewebsites.net/api"

# Upload and extract the ZIP file

Invoke-RestMethod -Uri "$apiBaseUrl/zip$($dstDirectory)" `
                    -Headers @{UserAgent="powershell/1.0"; `
                     Authorization=("Basic {0}" -f $base64AuthInfo)} `
                    -Method PUT `
                    -InFile ./tmp.zip `
                    -ContentType "multipart/form-data"
