What is Kubernetes?

Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available.

Kubernetes marks a breakthrough for devops because it allows teams to keep pace with the requirements of modern software development.  Kubernetes allows us to derive maximum utility from containers and build cloud-native applications that can run anywhere, independent of cloud-specific requirements.

Kubernetes Architecture:

Kubernetes follows a client-server architecture. … The master server consists of various components including a kube-apiserver, an etcd storage, a kube-controller-manager, a cloud-controller-manager, a kube-scheduler, and a DNS server for Kubernetes services.

How Kubernetes works?

Kubernetes keeps track of your container applications that are deployed into the cloud. It restarts orphaned containers, shuts down containers when they’re not being used, and automatically provisions resources like memory, storage, and CPU when necessary.
