How to update your cloud cloud service setup using Azure Powershell

Is it possible to update parameter value in Azure Cloud Service using Azure Powershell?

There is still no way to update just one parameter (the service management API does not allow it - it only accepts the entire service configuration) So, to update one parameter, you will need to update the entire configuration. And you can do it with PowerShell:

# Add the Azure Account first - this will create a login promppt
# when you have more then one subscription - you have explicitly select the one 
# which holds your cloud service you want to update
Select-AzureSubscription "<Subscription name with spaces goes here>"
# then Update the configuration for the cloud service
Set-AzureDeployment -Config -ServiceName "<cloud_service_name_goes_here>" `
                    -Configuration "D:/tmp/cloud/ServiceConfiguration.Cloud.cscfg" `
                    -Slot "Production"


For the `-Configuration 'parameter, I have provided the full local path to the new configuration file that I want to use with my cloud service.

This is a tried and tested solution.



As Astaykov says, you cannot update a single cloud configuration value using Powershell.

But you can read all the settings, update the one you want to change, save in a temporary file, and then set all the settings again:


    [string] $cloudService,
    [string] $publishSettings,
    [string] $subscription,
    [string] $role,
    [string] $setting,
    [string] $value

# param checking code removed for brevity

Import-AzurePublishSettingsFile $publishSettings -ErrorAction Stop | Out-Null

function SaveNewSettingInXmlFile($cloudService, [xml]$configuration, $setting, [string]$value)
    # get the <Role name="Customer.Api"> or <Role name="Customer.NewsletterSubscription.Api"> or <Role name="Identity.Web"> element
    $roleElement = $configuration.ServiceConfiguration.Role | ? { $ -eq $role }

    if (-not($roleElement))
        Throw "Could not find role $role in existing cloud config"

    # get the existing AzureServiceBusQueueConfig.ConnectionString element
    $settingElement = $roleElement.ConfigurationSettings.Setting | ? { $ -eq $setting }

    if (-not($settingElement))
        Throw "Could not find existing element in cloud config with name $setting"

    if ($settingElement.value -eq $value)
        Write-Host "No change detected, so will not update cloud config"
        return $null

    # update the value 
    $settingElement.value = $value

    # write configuration out to a file
    $filename = $cloudService + ".cscfg"

    return $filename

Write-Host "Updating setting for $cloudService" -ForegroundColor Green

Select-AzureSubscription -SubscriptionName $subscription -ErrorAction Stop  

# get the current settings from Azure
$deployment = Get-AzureDeployment $cloudService -ErrorAction Stop

# save settings with new value to a .cscfg file
$filename = SaveNewSettingInXmlFile $cloudService $deployment.Configuration $setting $value

if (-not($filename)) # there was no change to the cloud config so we can exit nicely

# change the settings in Azure
Set-AzureDeployment -Config -ServiceName $cloudService -Configuration "$pwd\$filename" -Slot Production

# clean up - delete .cscfg file
Remove-Item ("$pwd\$filename")

Write-Host "done"
