Azure Kubernetes 服务：如何设置整个节点池的污点？

Question

I have one node pool named " application pool " which contains node vm size of Standard_D2a_v4 . This node pool is set to " Autoscaling ". Is there in solution, where I taint the whole node pool in azure? to restrict the pods to schedule on that node pool?

Answer 1

Taints can be setup with the [--node-taints] flag only when you are adding a node pool with az aks nodepool add command:

Add a node pool to the managed Kubernetes cluster.

az aks nodepool add --cluster-name
                    --name
                    --resource-group
                    [--node-taints]

However, you cannot add taints to already existing node pool :

You can't change the node taints through CLI after the node pool is created.

A very similar topic is being discussed in this open thread .

So currently it is not possible to set taints to an existing node pool on AKS. But you can set them up while adding a new node pool to the managed cluster.

Answer 2

If you provisioned your cluster with Terraform, you can specify node_taints in azurerm_kubernetes_cluster_node_pool see here However, you can't add taints to default node pool
