如何使用 Azure Runbooks 按计划重启 Azure Web 应用

Question

我们有一个 Azure Web 应用程序，我们希望按计划设置自动重启。如果我想为此使用 Runbook，我该如何添加一个或多个应用程序以在不同的时间表上自动重启？

Answer 1

有多种不同的方法可以执行此操作，其中一些将取决于您拥有的 Azure-Runbook 模块版本。

您需要将用户设置为 'RunAsConnection' 用户
要获得连接，您可以使用 cmdlet：Get-AutomationConnection
然后要添加经过身份验证的帐户，您可以使用：Add-AzureRmAccount
如果您有多个订阅，则需要 select 订阅使用：Select-AzureRmSubscription
最后，使用Restart-AzureRmWebApp重启网络应用。

如果你设置了一个$result= Restart-AzureRmWebApp，如果$result为null，那么它不起作用，否则你会看到运行 webapp的状态。例如。 $result.State = "Running" 如果成功的话。

To do this on a schedule: go to your Runbook > Schedules > Add Schedule.

Add the input parameters, and select/create a recurring schedule. Click Ok and you're done!

*** If you use a parameter for your webAppName, then you can reuse the runbook, and just add different schedules with different input params

示例代码。

try
{
    $servicePrincipalConnection= Get-AutomationConnection -Name "AzureRunAsConnection"

    # Logging in to Azure
    $account = Add-AzureRmAccount `
        -ServicePrincipal `
        -TenantId $servicePrincipalConnection.TenantId `
        -ApplicationId $servicePrincipalConnection.ApplicationId `
        -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint

    Select-AzureRmSubscription -SubscriptionName "Azure subscription name"

    $result = Restart-AzureRmWebApp `
                -ResourceGroupName "Resource Name"
                -Name "Name of webapp you want to restart"

    if($result)
    {
        $state = $result.State
        Write-Output ("Web app restarted and is now $state")  #State should be Running at this point
    }
   else
   {
        Write-Output ("Web app did NOT restart")
   }
}
catch
{
    Write-Output ("Web app did NOT restart")
    throw $_.Exception
}

Because Az PowerShell modules now have all the capabilities of AzureRM PowerShell modules and more, we'll retire AzureRM PowerShell modules on 29 February 2024

这是 Az PowerShell 模块的更新示例。

filter timestamp {"[$(Get-Date -Format G)]: $_"}       
Write-Output "Script started." | timestamp 

$resourceGroupName = "your group"
$appServiceName = "your app service"
$subscriptionName = "your subscription"
try
{
    $conn = Get-AutomationConnection -Name "AzureRunAsConnection" 
    Connect-AzAccount -ServicePrincipal -Tenant $conn.TenantID -ApplicationId $conn.ApplicationID -CertificateThumbprint $conn.CertificateThumbprint | out-null

    # Select-AzureRmSubscription -SubscriptionName subscriptionName

    $result = Restart-AzWebApp -ResourceGroupName $resourceGroupName -Name $appServiceName

    if($result)
    {
        $state = $result.State
        Write-Output ("Web app restarted and is now $state")  #State should be Running at this point
    }
   else
   {
        Write-Output ("Web app did NOT restart")
   }
}
catch
{
    Write-Output ("Web app did NOT restart")
    throw $_.Exception
}
