Any idea, kubernetes is dropping default support to docker?

Vinod Kumar Nair:
From v1.20, you will start seeing this warning as docker support in kubelet being deprecated. The actual deprecation will happen till late 2021 with planned v1.22. So technically, if you have docker images for your application created before v1.20, those will continue to work/run in the Kubernetes worker nodes even with v1.22 as CRI has got just changed which has nothing to do with Docker, it could be containerD or CRI-O. Your CI/CD pipeline can continue to create images using Docker and run with any of the supported Container Runtime Interface in the Kubernetes like containerD or CRI-O (and not necessarily Docker). So if you have setup your Kubernetes cluster on public cloud like EKS, GKE or AKS then no worries…however if you have done by yourself using the cluster setup hardway then you need to change the CRI.
