I am attempting to create a pipeline that can automatically deploy via AWS-CodeDeploy and start a windows service on an EC2 instance, but I am having trouble getting the powershell scripting correct.

I have the following:

Appspec.yml

version: 0.0
os: windows
files:
 - source: 
 destination: C:tempMyApp
hooks:
 ApplicationStop:
 - location: DeploymentScriptsapplicationStop.bat
 timeout: 180
 ApplicationStart:
 - location: DeploymentScriptsapplicationStart.bat
 timeout: 180

applicationStart.bat

c:WindowsSystem32WindowsPowerShellv1.0powershell.exe C:tempMyAppDeploymentScriptsservice_create_start.ps1 -ServiceName MyService -BinaryPath 'C:tempMyAppMyService.exe' -DisplayName 'Test Application' -Description 'This is a test'

And the following powershell service_create_start.ps1:

Param([Parameter(Mandatory=$true)][string]$ServiceName,[Parameter(Mandatory=$true)][ValidateScript(Test-Path $_ -PathType 'leaf')][string]$BinaryPath, [string]$Displayname, [string]$Description)

If (Get-Service $ServiceName -ErrorAction SilentlyContinue) 

 If ((Get-Service $ServiceName).Status -eq 'Running') 

 Stop-Service $ServiceName
 Write-Host "Stopping $ServiceName"

 Else 

 Write-Host "$ServiceName found, but it is not running."

 

 Else 

 Write-Host "$ServiceName not found. Creating new Windows service."



$ArgumentList = '-Name "0" -BinaryPathName "1 -k netsvcs" -DisplayName "2" -StartupType Automatic -Description "3"' -f $ServiceName, $BinaryPath, $DisplayName, $Description

New-Service $ArgumentList

Start-Service $ServiceName

I created the bat file because it seemed that I could not launch a powershell script from code deploy with parameters. I am not otherwise tied to it.

My first problem is that it gets hung a prompt for "BinaryPathName" I have a feeling this is an issue with my quotes in one of these files.

My second problem (if I go enter this manually in testing) is that I get an Access is denied exception on the New-Service line.

To address this problem I have tried to use Start-Process an the RunAs verb to run an elevated powershell, however I am having trouble figuring out the syntax to add my parameters in (beyond the ps1 file name) with this syntax.

Am I even on the correct path here, or is there a better way to do this?

I dont think you can pass in parameters like this (as a single string), you better off using splatting:

$myInput = @
 Name = $ServiceName
 BinaryPathName = '0 -k netsvc' -f $BinaryPath
 StartupType = 'automatic' 
 DisplayName = $DisplayName
 Description = $Description

New-Service @myInput
