Kubernetes is a platform that eliminates the manual processes involved in deploying containerized applications. Today, both Docker and Kubernetes are leading container orchestration tools in the DevOps lifecycle. Once done, you will get a successful message that the master is up and running and nodes can now join the cluster. A node, in the context of Kubernetes, is a worker machine (virtual or physical, both apply) that Kubernetes uses to run applications (yours and those that Kubernetes needs to stay up and running).
