Kubernetes deprecates Docker, so you can't use Docker in Kubernetes now?
Use Case 1: Are you a developer?
Then, you are good to continue docker as is that you are using today. The reason is that the images generated by Docker are OCI Compliant, and are honoured by all CRI implemented run times like Containerd, CRI-O etc.,
Use Case 2: Are you a Kubernetes Administrator, but doesn’t use Docker Runtime in your cluster today?
You are good to continue, and aren’t impacted with this change
Use Case 3: Are you a Kubernetes Administrator, uses Docker Runtime in your cluster today?
You got some work to do, but don’t worry you have time till v1.22 of Kubernetes. Remember, Kubernetes supports 2 previous minor versions from current minor version.
