Terraform GCP – Remote Execute PowerShell in Windows Instance on Create

google-cloud-platformpowershellterraform

I have made a simple Terraform manifest that successfully initiates a Windows 2016 instance in GCP. As a next step I would like to execute a Powershell script to further configure and install software in the Windows instance.

I can not for my life find any example on how to execute a remote script through Terraform in a Windows GCP instance. For Linux instances it seems pretty straight forward, but how is it supposed to be done for Windows? Does anyone know any examples?

Any thoughts or ideas are much appreciated, thanks!

You can set the metadata to init your script like this:

resource "google_compute_instance" "default" {
 project = "your_project"
 zone = "us-central1-c"
 name = "tf-windows-script"
 machine_type = "f1-micro"
 boot_disk {
   initialize_params {
     image = "windows-server-2008-r2-dc-v20180710"
   }
 }
 network_interface {
   network = "default"
   access_config {
   }
 }
 metadata {
    windows-startup-script-url = "gs://your_bucket/startup.ps1"
  }
}

In my test the init script works without problems,

Here you can check the documentation of how to provide a startup script for Windows instances

Windows – Executing a git command using remote powershell results in a NativeCommmandError

As far as Powershell is concerned, it is the correct behaviour.

Unfortunately (at least in my opinon), git outputs a lot of information to stderr even when there isn't any error. For example git checkout -b somenewbranch will output things like modified file lists to stdout but the Switched to new branch somenewbranch message (which I think is the most relevant one) to stderr.

One of the most common ways to deal with this is to redirect stderr output to stdout, e.g:

git rebase master 2>&1

This is enough for most use cases I've seen. If you want to do something with the textual output itself you'll need to go a bit further as Powershell will store the stderr-originating lines as a RemoteException instead of a string. A brief example of how you might deal with something that needs to log output to the console:

$result  = Invoke-Expression "& git checkout -b somefeaturebranch 2>&1"

$output = ""
foreach($line in $result)
{
    $val = ""
    if($line.GetType().Name -eq "ErrorRecord")
    {        
        $val = $line.Exception.Message
    }else{
        $val = $line
    }   
    $output = "$output`r`n$val"
}

Write-Host $output

Powershell – AWS CodeDeploy Powershell Script fail to execute

This is how the CodeDeploy agent executes your script (source):

powershell.exe -ExecutionPolicy Bypass -File <absolute_path_to_your_script_here>

So try changing your hook to this:

hooks:
  BeforeInstall:
    - location: .\Deployment Scripts\IISCreateImageProcessorVirtualDirectory.ps1
      timeout: 900

The operator .\ allows you to run a script in the current directory.

General Troubleshooting

If you need to troubleshoot further, you can find your recent deployments here: C:\ProgramData\Amazon\CodeDeploy\

And your logs per deployment here: C:\ProgramData\Amazon\CodeDeploy\DEPLOYMENTGROUPIDGOESHERE\DEPLOYMENTIDGOESHERE\logs

You can write to host or stdout/stderr in your scripts, and if they are being run that output will end up in these logs.
