Scaling multiple kubernetes node pools on azure - azure

Question

I am in the middle of creating a function to schedule node pool scaling on azure.
This was fairly easy using the AKS Module and creating a function to scale the nodepool, but now the development team has started using multuple node pools in the same kubernetes service, usually i would just use the Set-AzAks as follow
Set-AzAks -Name <name> -ResourceGroupName <rgname> -NodeCount 1
But i seem unable to specify individual node pools in the command. I have been able to use the az CLI tool to get the functionality i want doing it manually, but I really want to use the azure automation account to do this.
Any help would be appreciated

This is an issue which already existed in the Github. So I think it's not a good way to use the PowerShell command Set-AzAks to scale the AKS nodes count in the current situation.
For this, I recommend you to use the Azure REST API Managed Clusters - Create Or Update through PowerShell, it will also work perfectly as the Azure CLI commands for you.
Update:
As you wish, I will show you the example below:
$body = '{
"location": "eastus",
"properties": {
"kubernetesVersion": "1.14.6",
"dnsPrefix": "xxxxx",
"agentPoolProfiles": [
{
"count": 2,
"vmSize": "Standard_DS2_v2",
"osDiskSizeGB": 100,
"vnetSubnetID": "xxxxxxxx",
"maxPods": 30,
"osType": "Linux",
"type": "AvailabilitySet",
"orchestratorVersion": "1.14.6",
"name": "agentpool"
}
],
"addonProfiles": {
"httpapplicationrouting": {
"enabled": false,
"config": {}
},
"omsagent": {
"enabled": true,
"config": {
"loganalyticsworkspaceresourceid": "xxxxxxxx"
}
}
},
"nodeResourceGroup": "xxxxxxxxx",
"enableRBAC": true,
"networkProfile": {
"networkPlugin": "azure",
"serviceCidr": "10.1.0.0/16",
"dnsServiceIP": "10.1.0.10",
"dockerBridgeCidr": "172.17.0.1/16",
"loadBalancerSku": "Basic"
}
}
}'
$requestUri = "https://management.azure.com/subscriptions/{subscription_id}/resourceGroups/{your_group_name}/providers/Microsoft.ContainerService/managedClusters/{your_cluster_name}?api-version=2019-08-01"
$accessToken = "xxxxxxx"
Invoke-RestMethod -Headers #{Authorization = "Bearer $accessToken"} -Uri $requestUri -Method PUT -ContentType 'application/json' -Body $body
You can change the context in the body as you need and the properties describe in the REST API.
