@Mumshad Mannambeth @Trung Tran I have a question in k8s upgrade. when i am checking latest k8s version to upgrade using kubadm upgrade plan command i am getting below output-
root@master-vm:/home/ubuntu# kubeadm upgrade plan
[upgrade/config] Making sure the configuration is correct:

[upgrade/config] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -o yaml'

[upgrade/versions] Cluster version: v1.21.6
