Stop all compute in AKS (Azure Managed Kubernetes)

You could use the Azure CLI to stop the the entire cluster:

az aks stop --name myAksCluster --resource-group myResourceGroup

And start it again with

az aks start --name myAksCluster --resource-group myResourceGroup

Before this feature, it was possible to stop the virtual machines via Powershell:

az vm deallocate --ids $(az vm list -g MC_my_resourcegroup_westeurope --query "[].id" -o tsv)

Replace MC_my_resourcegroup_westeurope with the name of your resource group that contains the VM(s).

When you want to start the VM(s) again, run:

az vm start --ids $(az vm list -g MC_my_resourcegroup_westeurope --query "[].id" -o tsv)

Only VMs cost money out of all AKS resources (well, VHDs as well, but you cannot really stop those). So you only need to take care of those. Edit: Public Ips also cost money, but you cannot stop those either.

For my AKS cluster I just use portal and issue stop\deallocate command. And start those back when I need them (everything seems to be working fine).

You can use REST API\powershell\cli\various SKDs to achieve the same result in an automated fashion.

Above method (az vm <deallocate|start> --ids $(...)) no longer seems to work.

Solved by first listing the VM scale sets and use these to deallocate/start:

$ResourceGroup = "MyResourceGroup"$ClusterName = "MyAKSCluster"$Location = "westeurope"$vmssResourceGroup="MC_${ResourceGroup}_${ClusterName}_${Location}"# List all VM scale sets$vmssNames=(az vmss list --resource-group $vmssResourceGroup --query "[].id" -o tsv | Split-Path -Leaf)# Deallocate first instance for each VM scale set$vmssNames | ForEach-Object { az vmss deallocate --resource-group $vmssResourceGroup --name $_  --instance-ids 0}# Start first instance for each VM scale set$vmssNames | ForEach-Object { az vmss start --resource-group $vmssResourceGroup --name $_  --instance-ids 0}
