Pods are associated to services through key-value pairs called labels and selectors. Any new pod with labels that match the selector will automatically be discovered by the service. node. The node pulls the images from the container image registry and coordinates with the local container runtime to launch the container. etcd is an open source, distributed key-value database from CoreOS, which acts as the single source of truth (SSOT) for all components of the Kubernetes cluster.

This architecture of Kubernetes makes it modular and scalable by creating an abstraction between the applications and the underlying infrastructure. Key Design Principles Kubernetes is designed on the principles of scalability, availability, security distributing the workload across available resources. This section will highlight some of the key attributes of Kubernetes. Workload Scalability Applications deployed in Kubernetes are packaged as microservices. These microservices are composed of multiple containers grouped as pods. Each container is designed to perform only one task. Pods can be USE CASES FOR KUBERNETES 10
