Pod Antiaffinity Feature

[amitdrana]

Hi Team,
IS Karpenter supports the Pod anti-affinity feature as we are using it for our application deployment.
also, we are using nodeAffinity with the following match expression.
Not able to set node.kubernetes.io/role label on the pod. any other way I can use this?

 nodeAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            nodeSelectorTerms:
            - matchExpressions:
              - key: node.kubernetes.io/role
                operator: In
                values:
                - ToolsOnDemand

Support for pod affinity and anti-affinity is being tracked at #942 .

You can have Karpenter apply a label to nodes that it creates, but it can't be in the node.kuberntes.io domain. If you modify your provisioner to include labels:

  labels:
    my/role: ToolsOnDemand

and change the nodeAffinity on your pod to select it, it will create nodes with that label and allow your pods to schedule.
