The Cloud service program executes PowerShell scripts when it is started

If the PowerShell script needs to be executed at the start of the cloud service program, we need to embed the script in the program and write a cmd to execute the script, as follows:

1. Writing a test PowerShell script: Detecting DNS every 10 minutes

$TimeStart= get-Date$TimeEnd=$timeStart. AddMinutes (1440)$name="cnppmedia.blob.core.chinacloudapi.cn."$result="D:\nslookuplog.txt"Write-host"Start time: $TimeStart"Write-host"End time: $TimeEnd" Do {  $TimeNow= get-Dateif($TimeNow -ge $TimeEnd) {Write-host"It ' s time to finish." }   Else{try {Write-host"===========nslookup====current Time: $ (get-date) =============="Invoke-command-scriptblock{Write-output"===========test at Azure ====current time: $ (get-date) =============="| Out-file-filepath$result-append-Force } Invoke-command-scriptblock{nslookup$name| Out-file-filepath$result-append-Force }} Catch {}} Start-sleep-seconds 600  }  Until($TimeNow -ge $TimeEnd)

2. Write a cmd file to execute the script:

" Set-executionpolicy Unrestricted " echo Start test Dnspowershell. \TESTDNS.PS1 if %errorlevel% neq 0/b 0

3. Embed the 2 files in the program and set the Copy always property:

4. Modify the Csdef file to add startup task startup

<?xml version="1.0"encoding="Utf-8"? ><servicedefinition name="testdnswithsdk26"xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition"schemaversion="2015-04.2.6"> <webrole name="WebRole1"Vmsize="Small"> <Startup> <task commandline="Testdns.cmd"executioncontext="elevated"Tasktype="background"/> </Startup> <Sites> <site name="Web"> <Bindings> <binding name="Endpoint1"Endpointname="Endpoint1"/> </Bindings> </Site> </Sites> <ConfigurationSettings> <setting Name ="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString"/> </ConfigurationSettings> <Endpoints> <inputendpoint name="Endpoint1"Protocol="http"port=" the"/> </Endpoints> </WebRole></ServiceDefinition>

The task type needs to be set to backgroundbecause the PowerShell script that is being tested is executed continuously for a period of time, otherwise the deployment cannot be completed
