How to create a schedule which triggers the runbook using PowerShell command? - powershell

Question

I'm trying to create a schedule to trigger a runbook using PowerShell commands in Azure Automation account. Runbook is taking resourcevariable which is an automation variable as an input parameter.
I am able to create a schedule, but I am not able to register it as it is throwing the error:
Invalid runbook parameters
How can I register it and trigger a runbook ?
My code:
$TimeZone = ([System.TimeZoneInfo]::Local).Id
$scheduleName = "newschedule1"
$automationAccountName = "SentinelAutomationAccount"
$resourcegroupName = "myrg"
$RunbookName = "runbook1"
$params = #{"resourcevariable" = $resourcevariable;"flag" = $false}
$starttime = (Get-Date).AddMinutes(40)
$schedule = New-AzAutomationSchedule –AutomationAccountName $automationAccountName –Name $scheduleName –StartTime $starttime -OneTime -ResourceGroupName $resourcegroupName -TimeZone $TimeZone
Register-AzAutomationScheduledRunbook -AutomationAccountName $automationAccountName -RunbookName $RunbookName -ScheduleName $scheduleName -ResourceGroupName $resourcegroupName -Parameters $params
Runbook1 script: (5.1 version)
param (
[Parameter(Mandatory = $true)]
[string] $resourcevariable
)
# Login to Azure
try
{
"Logging in to Azure..."
Connect-AzAccount -Identity
}
catch {
Write-Error -Message $_.Exception
throw $_.Exception
}
$TimeZone = ([System.TimeZoneInfo]::Local).Id
$automationAccount = "xxxAutomationAccount"
$resourcegroup = "xxx"
$scheduleName = "myschedule"
$Runbook = "xxxRunBook"
$params = #{"resourcevariable" = "resourcevariable";"flag" = "false"}
$starttime = (Get-Date).AddMinutes(40)
$schedule = New-AzAutomationSchedule –AutomationAccountName $automationAccount –Name $scheduleName –StartTime $starttime -OneTime -ResourceGroupName $resourcegroup -TimeZone $TimeZone
Register-AzAutomationScheduledRunbook -AutomationAccountName $automationAccount -RunbookName $Runbook -ScheduleName $scheduleName -ResourceGroupName $resourcegroup -Parameters $params.Parameters
Runbook2 script: (7.1 version)
param (
[Parameter(Mandatory = $true)]
[string] $resourcevariable
)
# Login to Azure
try
{
"Logging in to Azure..."
Connect-AzAccount -Identity
}
catch {
Write-Error -Message $_.Exception
throw $_.Exception
}
echo "From Runbook2"

I tried it in my environment and found the same error.
When trying to retrieve parameters stored in the params variable, we should specify them as $params.parameters.
I modified the script and was able to correctly register and trigger the schedule.
Modified script:
$params = #{"resourcevariable" = "resourcevariable";"flag" = "false"}
Register-AzAutomationScheduledRunbook -AutomationAccountName $automationAccount -RunbookName $Runbook -ScheduleName $scheduleName -ResourceGroupName $resourcegroup -Parameters $params.Parameters
myschedule.ps1:
$TimeZone = ([System.TimeZoneInfo]::Local).Id
$automationAccount = "xxxxautomationaccount"
$resourcegroup = "xxxResourcegroup"
$scheduleName = "xxxxxschedule"
$Runbook = "xxxxrunbook"
$params = #{"resourcevariable" = "resourcevariable";"flag" = "false"}
$starttime = (Get-Date).AddMinutes(40)
$schedule = New-AzAutomationSchedule –AutomationAccountName $automationAccount –Name $scheduleName –StartTime $starttime -OneTime -ResourceGroupName $resourcegroup -TimeZone $TimeZone
Output:
Scheduled in Portal successfully:
Note: Run the same script in runbook with the changes given above to get the same results.
