All the nodes run an agent that’s called kubelet and the master runs other components such as APIs (application programming interfaces) and a scheduler. All the nodes have Docker and are managed from the master systems. Kubelet is in charge of managing the Pods and the containers in all aspects. We’ll talk more about pods later, but now just think of them as an abstraction that groups containers. The nodes also run a network proxy and load balancer. These allow us to have static end points for our container, which are defined through services.
