Basic Concepts

Node also known as minion is a machine which kubernetes is installed, Kublet is the agent running on each minion on the cluster, etcd is responsible to hold information and logs about the cluster, the scheduler is responsible for distributing containers across the nodes. Controllers analyze the cluster and can bring up more containers if they are needed.
