Filters and Kubernetes Annotations visibility

[PaulE]

Trying to set up a filter using an annotation value for worker nodes in a K8S cluster .. the node currently has 

$ kubectl get node ag1-sres-workload-01-md-0-85585fc84d-4q6h4 -o yaml
apiVersion: v1
kind: Node
metadata:
  annotations:
    cluster.x-k8s.io/cluster-name: xxx-xxx-xxx
    cluster.x-k8s.io/cluster-namespace: default
    cluster.x-k8s.io/machine: xxx-xxx-xxx-md-0-85585fc84d-4q6h4
    cluster.x-k8s.io/owner-kind: MachineSet
    cluster.x-k8s.io/owner-name: xxx-xxx-xxx-md-0-85585fc84d
    csi.volume.kubernetes.io/nodeid: '{"csi.vsphere.vmware.com":"xxx-xxx-xxx-md-0-85585fc84d-4q6h4"}'
    kubeadm.alpha.kubernetes.io/cri-socket: /var/run/containerd/containerd.sock
    node.alpha.kubernetes.io/ttl: "0"
    volumes.kubernetes.io/controller-managed-attach-detach: "true"
  creationTimestamp: "2023-07-13T08:37:59Z"

    beta.kubernetes.io/os: linux
    kubernetes.io/arch: amd64
    kubernetes.io/hostname: xxx-xxx-xxx-md-0-85585fc84d-4q6h4
    kubernetes.io/os: linux
    node.kubernetes.io/instance-type: vsphere-vm.cpu-16.mem-64gb.os-photon

 When I am in Data Explorer and get to Kubernetes nodes:Kubernetes labels I only see the labels and not the annotations. I'd like to be able to filter on the annotation cluster.x-k8s.io/owner-kind: MachineSet which I thought would appear as a label. How do I filter on the annotation ?

You can use kubectl with the -o jsonpath option to filter resources based on annotations. For example, to get all nodes with the annotation cluster.x-k8s.io/owner-kind: MachineSet, you can use the following command:

kubectl get nodes -o jsonpath='{.items[?(@.metadata.annotations.cluster\.x-k8s\.io/owner-kind=="MachineSet")].metadata.name}'

This command uses a jsonpath expression to filter the nodes based on the value of the cluster.x-k8s.io/owner-kind annotation.

Sorry, to clarify, I'm trying to filter in Data Explorer
