Its probably because you already have docker installed, I assume the most recent version from the docker repo. That command is trying to install it again from a different repo. Try running this instead:
sudo yum install -y kubelet kubeadm kubectl kubernetes-cni
It will install the required kubernetes tools without docker.
You are mixing docker packages. Package docker is Redhat's Docker. Package docker-engine is Docker's Docker. kubernetes-node has Docker's docker dependency + you are asking to install also Redhat's Docker => conflict. Try:
sudo yum install docker-engine kubernetes-node
