Kubernetes (k8s) is a platform for automating deployment, scaling, and operations of application containers. This paper describes the Kubernetes architecture and its design principles. It also highlights how Kubernetes solves the challenges of cloud-native application development and deployment.
The paper starts with an introduction to containerization and the challenges that come with it. It then introduces Kubernetes as a solution to these challenges by providing automation for deploying, scaling, and managing containerized applications. The paper discusses the key components of Kubernetes such as the API server, scheduler, controller manager, etcd, and kubelet.
The authors go on to describe how Kubernetes provides declarative management of applications through the use of labels, annotations, and selectors. They also explain how Kubernetes provides high availability through replication controllers and self-healing mechanisms.
Finally, the paper covers some advanced topics such as network integration with CNI plugins, load balancing with ingress controllers, and storage orchestration with volume plugins.
Overall, this paper provides a comprehensive overview of Kubernetes’ design principles and architecture. It is an essential read for anyone interested in understanding how Kubernetes works under the hood or looking to implement it in their organization.
