Powershell G-cloud attach disk to instance

Question

I`m following the documentation: https://googlecloudplatform.github.io/google-cloud-powershell/#/google-compute-engine/GceInstance/Set-GceInstance

I cant get the following code working:

$disk = Get-GceDisk disk-snapshot-instance-1
Set-GceInstance -Name instance-1 -AttachDisk $disk

When I replace $disk for disk-snapshot-instance-1 I get the same error:

Set-GceInstance : Parameter set cannot be resolved using the specified named parameters.
At line:1 char:1
+ Set-GceInstance -Name instance-1 -AttachDisk $disk
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Set-GceInstance], ParameterBindingException
    + FullyQualifiedErrorId : AmbiguousParameterSet,Google.PowerShell.ComputeEngine.SetGceInstanceCmdlet

The thing I don't understand is that it works for me to remove a disk when attaching it manually through the G-cloud interface.

Set-GceInstance -Name instance-1 -RemoveDisk $disk

My question: Why can't I attach a disk to an instance with the above code, while removing the disk works?

Did you resolve this? If not, I'll try to repro it for you this afternoon. Are you using Get-GceDisk to set $disk before the remove too? — DazWilkin

The correct commands are:

Set-GceInstance $instance -AddDisk $disk1 -Zone $zone
Set-GceInstance $instance -RemoveDisk $disk1 -Zone $zone

I create an instance with 2 disks using gcloud and then:

Get-GceDisk | Format-List -Property Name

This returns:

Name : disk-1
Name : disk-2
Name : instance-1

Then I can:

$zone = "us-west1-c"
$disk2 = Get-GceDisk disk-2
Set-GceInstance instance-1 -RemoveDisk $disk2 -Zone $zone
Set-GceInstance instance-1 -AddDisk $disk2 -Zone $zone
