[upgrade/versions] Cluster version: v1.20.2
[upgrade/versions] kubeadm version: v1.20.2
I1023 06:15:25.625831 14513 version.go:251] remote version is much newer: v1.22.2; falling back to: stable-1.20
[upgrade/versions] Latest stable version: v1.20.11

[upgrade/versions] Latest version in the v1.20 series: v1.20.11
[upgrade/versions] Latest version in the v1.20 series: v1.20.11
Components that must be upgraded manually after you have upgraded the control plane with 'kubeadm upgrade apply':
COMPONENT CURRENT AVAILABLE
kubelet 2 x v1.20.2 v1.20.11
Upgrade to the latest version in the v1.20 series:
COMPONENT CURRENT AVAILABLE
kube-apiserver v1.20.2 v1.20.11
kube-controller-manager v1.20.2 v1.20.11
kube-scheduler v1.20.2 v1.20.11
kube-proxy v1.20.2 v1.20.11
CoreDNS 1.7.0 1.7.0
etcd 3.4.13-0 3.4.13-0
You can now apply the upgrade by executing the following command:
kubeadm upgrade apply v1.20.11
Note: Before you can perform this upgrade, you have to update kubeadm to v1.20.11.
_____________________________________________________________________
The table below shows the current state of component configs as understood by this version of kubeadm.
Configs that have a "yes" mark in the "MANUAL UPGRADE REQUIRED" column require manual config upgrade or
resetting to kubeadm defaults before a successful upgrade can be performed. The version to manually
upgrade to is denoted in the "PREFERRED VERSION" column.
