如何使用Azure Powershell更新Azure Cloud Service設置

Question

是否可以使用Azure Powershell更新Azure Cloud Service中設置的值？

Answer 1

到目前爲止，沒有辦法更新只有一個設置（服務管理API不允許它 - 它只接受整個服務配置）。所以，爲了更新一個設置，你將不得不更新整個配置。你可以使用PowerShell做到這一點：

# Add the Azure Account first - this will create a login promppt 
Add-AzureAccount 
# 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" 

爲我提供新的配置文件，我想用我的雲服務使用完整的本地路徑的`構成 - 」參數。

這是驗證和工作的解決方案。

正如astaykov所說，您無法使用Powershell更新單個雲配置值。

但你可以閱讀所有的設置，更新你想改變，它保存到臨時文件，然後重新設置所有的設置，像這樣的一個：

UpdateCloudConfig.ps1：

param 
(
    [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 | ? { $_.name -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 | ? { $_.name -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" 
    $configuration.Save("$pwd\$filename") 

    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 
{ 
    return 
} 

# 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"
