I need to upgrade kubernetes from 1.18.4 -> 1.21.10 and retain the use of docker as my cri. Normally conatinrd will auto install with kubernetes greater than 1.21 . It is recomended that a cluster be upgraded 1 version at a time so we will follow: 1.18.4 -> 1.19.16 -> 1.20.15 -> 1.21.12 https://kops.sigs.k8s.io/operations/updates_and_upgrades/…
