Getting Started with Communication
In this lesson, we will find out why we need to establish communication between Pods.
The Problem
Pods are the smallest unit in Kubernetes and have a relatively short life-span. They are born, and they are destroyed. They are never healed. The system heals itself by creating new Pods (cells) and by terminating those that are unhealthy or those that are surplus. The system is long-living, Pods are not.
Controllers, together with other components like the scheduler, are making sure that the Pods are doing the right thing. They control the scheduler. We used only one of them so far.
