My guess you want to create kubernetes cluster in docker environment, this is possible but your approach might not as good as you think.
There is KinD for that. It is actually what you want.
However if you still want to use your implementation. You should use DinD as base image, bind volume to local docker then use kubeadm in dockerfile as "CMD" not as "RUN".
