Tutorial of Kubernetes For Beginners

Introduction

Kubernetes is an open-source container management system developed in the Google platform for managing containerized applications across a cluster of nodes means it is used for automating application deployment, scaling, and management. It provides a platform that helps us for automating deployment, scaling, and operations of application containers across clusters of hosts and it is a highly flexible container tool to deliver even complex applications, consistently. 

What can Kubernetes do for us?
 

Now a day, users expect applications to be available 24/7, and developers expect to deploy new versions of those applications several times a day they never accept downtime. So, to avoid downtime developers have to find a method of Containerization to perform maintenance and update without interrupting their services means enabling applications to be released and updated in an easy and fast way without any downtime.

A container is a standard unit of software that makes it easy for a developer to edit, deploying apps and all its dependencies so the application runs quickly and reliably from one computing environment to another. It includes everything needed for application to run and Kubernetes helps us to make sure those containerized applications run where and when we want and helps to find the resources and tools to work.

Features of Kubernetes

• Automated rollouts & rollback: In running application if we made some changes in application and after that changes in application something goes wrong then Kubernetes will rollback for us and avoid the application downtime.
• Container balancing: Kubernetes always knows when and where to place containers by calculating the best location for them.
• Run everywhere: Kubernetes has the advantage of on-premises public cloud infrastructure and letting us move workloads anywhere we want.
• Interacts with several groups of containers: Kubernetes has the ability to manage multiple clusters at the same time.
• Provides additional services: Kubernetes also offers security, networking and storage services.
• Self-monitoring: Kubernetes checks constantly the health of nodes and containers to maintain the stability of the application.
• Horizontal scaling: Kubernetes allows us to scale resources not only vertically but also horizontally, easily and quickly.
• Storage orchestration: Kubernetes mounts and adds storage system of our choice to run applications.

Kubernetes features help a lot to improve the IT field’s work because it provides solutions like test and autocorrection of applications, Control and automates deployments and updates and etc.
