问题
I am working on this official tutorial from MS Azure team to run a PowerShell Workflow runbook
to start a VM
. But when I start the following runbook (from step 6 of the tutorial), I get the error shown below. Question: What I may be missing, and how can we resolve the issue?
Remark: Start-AzVM is from Az.Compute module that I have already imported.
runbook code:
workflow MyFirstRunbook-Workflow
{
# Ensures that you do not inherit an AzContext in your runbook
Disable-AzContextAutosave –Scope Process
$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Connect-AzAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationId $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint
$AzureContext = Get-AzSubscription -SubscriptionId $Conn.SubscriptionID
Start-AzVM -Name 'vm-cs-web01' -ResourceGroupName 'rg-cs-ansible1' -AzContext $AzureContext
}
Error:
Start-AzVM : Cannot bind parameter 'DefaultProfile'. Cannot convert the "a76c7e8f-210d-45e5-8f5e-525015b1c881" value of
type "Deserialized.Microsoft.Azure.Commands.Profile.Models.PSAzureSubscription" to type
"Microsoft.Azure.Commands.Common.Authentication.Abstractions.Core.IAzureContextContainer".

回答1:
Looks like it is a mistake in the doc, in this scenario, it should use Set-AzContext
to set the subscription instead of using Get-AzSubscription
to get the subscription, change the command like below, it will work fine.
workflow MyFirstRunbook-Workflow
{
# Ensures that you do not inherit an AzContext in your runbook
Disable-AzContextAutosave –Scope Process
$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Connect-AzAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationId $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint
$AzureContext = Set-AzContext -SubscriptionId $Conn.SubscriptionID
Start-AzVM -Name 'vm-cs-web01' -ResourceGroupName 'rg-cs-ansible1' -AzContext $AzureContext
}
