Kubernetes(k8) is an orchestration platform to manage containers.
Kubernetes is the buzzword in the market because of the boom of containerization and microservices. We can have a microservices architecture with its pros and cons and plenty of containers but the question is how to manage those containers and the source of truth is K8.
It was originally designed by Google, and is now maintained by the Cloud Native Computing Foundation. It aims to provide a “platform for automating deployment, scaling, and operations of application containers across clusters of hosts”.
The definition is from the k8 official website.
In this article, we will list down 5 free resources to which will help you to learn k8.
- Learn K8 basics:- Learn Kubernetes Basics is the official documentation by the developers of Kubernetes. This tutorial will help you to understand the basics step by step guide of k8 cluster orchestration system. Each module contains some background information on major Kubernetes features and concepts and includes an interactive online tutorial. I think this the source of truth to start learning k8.
- Learning Path kubernetes:- This course can give us from Kubernetes basics to advanced networking and workloads. This tutorial series introduced by IBM and its very good resource to deep dive into k8. If you’re new to Kubernetes and container orchestration and want to begin learning about it, this learning path covers everything from basic prerequisites to more advanced skills needed for containerization. This course will give you brief the idea about a container up to advance k8 concepts. After completion of this course, you will be able to understand the basics of containers, build containerized applications and deploy them onto Kubernetes, understand the advantages of a deployment that uses Helm with Kubernetes, deploy various microservices with Kubernetes, understand basic networking for applications that are running in Kubernetes and much more.
- A Tutorial Introduction to Kubernetes:- A Tutorial Introduction to Kubernetes is provided by Ulaş Türkmen on his blog. In this tutorial series, you will learn how to use Kubernetes using Minikube, how to configure kubectl, understanding nodes and namespaces, how to use the dashboard, deploying various container images in order to demonstrate Kubernetes feature, running service, etc.
- Coursera K8:- Architecting with Google Kubernetes Engine Specialisation this is the course name. Actually, this course is design and developed by Google. In this k8 course you will learn, how to implement solutions using Google Kubernetes Engine, or GKE, including building, scheduling, load balancing, and monitoring workloads, as well as providing for the discovery of services, managing role-based access control and security, and providing persistent storage to these applications.
- Fundamentals of Containers, Kubernetes, and Red Hat OpenShift:- This course will provide you with an introduction to container and container orchestration technology using Docker, Kubernetes, and Red Hat OpenShift Container Platform. You will learn how to containerize applications and services, test them using Docker, and deploy them on a Kubernetes cluster using Red Hat OpenShift. Additionally, you will build and deploy an application from source code using the Source-to-Image facility of Red Hat OpenShift. After the completion of this course, you will be able to create containerized services, manage containers and container images, create custom container images and deploy containerized applications on Red Hat OpenShift.
Summary:- Modern applications are increasingly built using containers, microservices packaged with their dependencies and configurations. K8s is open-source orchestration software for deploying and managing those containers at scale. With K8s, you can build, deploy, deliver and scale containerized apps faster and smoother.
This is just a list of the sources from where we can start our journey and makes hands dirty. There is a more complete list of concepts available on the Kubernetes website. I suggest you give them a quick look if you want to get a better grasp of who does what and what goes where.
This is it, for now, please let me know if you know more resources which are very simple and effective.
