Kubernetes is a container management technology developed in Google lab to manage containerized applications in different kind of environments such as physical, virtual, and cloud infrastructure. It is an open source system which helps in creating and managing containerization of application. This tutorial provides an overview of different kind of features and functionalities of Kubernetes and teaches how to manage the containerized infrastructure and application deployment.

Audience

This tutorial has been prepared for those who want to understand the containerized infrastructure and deployment of application on containers. This tutorial will help in understanding the concepts of container management using Kubernetes.

Prerequisites

We assume anyone who wants to understand Kubernetes should have an understating of how the Docker works, how the Docker images are created, and how they work as a standalone unit. To reach to an advanced configuration in Kubernetes one should understand basic networking and how the protocol communication works.

Overview

Kubernetes in an open source container management tool hosted by Cloud Native Computing Foundation (CNCF). This is also known as the enhanced version of Borg which was developed at Google to manage both long running processes and batch jobs, which was earlier handled by separate systems.

Kubernetes comes with a capability of automating deployment, scaling of application, and operations of application containers across clusters. It is capable of creating container centric infrastructure.

Features of Kubernetes

Following are some of the important features of Kubernetes.

• Continues development, integration and deployment
• Containerized infrastructure
• Application-centric management
• Auto-scalable infrastructure
• Environment consistency across development testing and production
• Loosely coupled infrastructure, where each component can act as a separate unit
• Higher density of resource utilization
• Predictable infrastructure which is going to be created

One of the key components of Kubernetes is, it can run application on clusters of physical and virtual machine infrastructure. It also has the capability to run applications on cloud. It helps in moving from host-centric infrastructure to container-centric infrastructure.
