Docker helps to create lightweight LINER BASED container while Kubernetes helps in orchestrating and managing containers. OpenShift is built on top of Docker and Kubernetes. All the containers are built on top of Docker cluster, which is basically Kubernetes SERVICE on top of Linux machines, using Kubernetes orchestrations feature. In this PROCESS, we build Kubernetes master which CONTROLS all the nodes and deploys the containers to all the nodes. The main function of Kubernetes is to control OpenShift cluster and deployment flow using a different kind of configuration file. As in Kubernetes, we use kubctl in the same way we use OC command line utility to build and deploy containers on cluster nodes.
