Introduction to Kubernetes

Kubernetes is an open-source container orchestration system for automating application deployment, scaling, and management. It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation. Kubernetes is the most widely used container orchestration system and is used by many organizations to manage their cloud-native applications.

Kubernetes provides a number of features that make it easy to deploy, scale, and manage cloud-native applications. It provides a unified control plane to manage the underlying infrastructure and provides a declarative approach to application deployment. It also provides automated rollouts, rollbacks, and canary deployments which make it easier to deploy applications.

Kubernetes is built on the concept of Pods, which are the basic building blocks for deploying applications. A Pod is a group of one or more containers that are deployed together and are managed as a single entity. Kubernetes also provides a number of other abstractions such as Services, Replica Sets, and Deployments which make it easier to manage complex applications.

Kubernetes can be used to deploy applications on any cloud provider or on-premise. It provides a number of tools and APIs to help manage the deployment and scaling of applications. Kubernetes also provides a number of add-ons which can be used to extend the functionality of the system.
