Kubernetes (commonly stylized as k8s) 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. It aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts". It works with a range of container tools, including Docker. Many cloud services offer a Kubernetes-based platform or infrastructure as a service (PaaS or IaaS) on which Kubernetes can be deployed as a platform-providing service. Many vendors also provide their own branded Kubernetes distributions.

Free Courses to Learn Kubernetes for Developers

Even though these courses are free but they are nice courses and just made free by their instructor for promotional and educational purposes.

If you are starting with Kubernetes, I suggest you join one of these courses to get a feel of what is Kubernetes.

1. Introduction to Kubernetes

In this course, we'll discuss some of Kubernetes' basic concepts and talk about the architecture of the system, the problems it solves, and the model that it uses to handle containerized deployments and scaling.

This course offers an introduction to Kubernetes and includes technical instructions on how to deploy a stand-alone and multi-tier application. You’ll learn about ConfigMaps and Secrets, and how to use Ingress.

Upon completion, developers will have a solid understanding of the origin, architecture and building blocks for Kubernetes, and will be able to begin testing the new cloud native pattern to begin the cloud native journey.

2. Learn DevOps Kubernetes deployment by kops and terraform


This is another practical course to learn Kubernetes on AWS by using kops and Terraform. In this course, you will learn how to deploy a Kubernetes cluster in AWS and how to use Terraform to run an immutable infrastructure.

You will also learn about the horizontally scaled deployment in Kubernetes and how to use Kops to spin up the Kubernetes cluster.

Most importantly, you will learn how to see logs, get inside the Docker container within the pod in Kubernetes.

3. Just enough kubernetes to be dangerous

This course would serves as the first step in your kubernetes journey. It would help you get started with Kubernetes quickly and build a foundation while learning by practicing it. This is a really nice course to learn Kubernetes in a short time.

You will not only set up kubernetes cluster with Google Kubernetes Engine but also learn how to deploy a micro-services application and publish it to the world.

You will also learn how to dynamically scale your application using the auto-scaling feature of kubernetes, and release application updates without any downtime, or, achieve Zero downtime deployments.

4. Getting Started with Kubernetes

This course will teach you the theory and practical skills required to get you up and running as fast as possible.

The course can be logically divided into three parts. In the first part, you'll dive into Kubernetes architecture, what the main components and services are, and how they come together to build a production-class container infrastructure.

In the second and third part, you'll learn how to install and deploy Kubernetes on several cloud platforms and learn to work with pods, deployments, and services.

By the end of this course, you'll have a solid understanding of what Kubernetes is and how it works, as well as skills to deploy a Kubernetes cluster and simple applications.

5. Containers 101

In this course, introduce the basics of building and deploying packaged applications. You will learn the concepts of containers provided by Docker and how to create them. You will learn the essentials for modern DevOps with the arrangement, packaging and many other things built on the fast growing Docker, Kubernetes and Helm.

That's all about some of the free courses to learn Kubernetes in 2020. As I have said, Kubernetes is one of the most important container management technology and really important if you are thinking about DevOps in Cloud. I suggest you to spend some time learning various tools and features offered by Kubernetes for scaling your containers, including the auto-scaling feature of Kubernetes.

The automation and infrastructural capabilities of Kubernetes makes it an ideal technological partner for DevOps. In this article, you'll see 10 ways Kubernetes enables DevOps

DevOps was an idea before its time.

It actually took a while for technology to catch up and fully implement the principles and vision of DevOps, but that is how innovation works.

A new set of tools in our toolboxes (though it's now taking up more and more mindshare) is end-to-end automation, and Kubernetes helps you manage that. Kubernetes is an open source framework for "automating deployment, scaling, and management of containerized applications." Originally introduced by Google, Red Hat, and others pushed it forward the last 3-4 years.

At the 2017 All Day DevOps conference, Siamak Sadeghianfar laid out 10 ways Kubernetes enables DevOps. We thought it was worth revisiting what he had to say as **Kubernetes **only becomes more prominent.

**So, how exactly does Kubernetes enable DevOps? Let's dive into what Siamak had to say: **

1. Deployment automation.

You should automate every step of your delivery pipeline. Kubernetes automates the deployment of containers. Each component becomes a container image.

**2. Infrastructure as code. **

With **Kubernetes **your entire infrastructure is code. This means any part in your application (databases, ports, access controls, etc.) can be described in a way **Kubernetes **can use. For example, you store your infrastructure code in a version-control repository. **Kubernetes **takes the code, and based on instruction, deploys, and maintains your infrastructure. This happens automatically and consistently.

3. Configuration as code.

**Kubernetes **allows you to "configure as code." Traditionally, an admin had to run configuration scripts manually to make sure they get the right one. **Kubernetes **keeps the file in the source repo. This allows you to describe where the file needs to go in the container and how the application consumes it. Additionally, it can be version controlled.

4. Immutable infrastructure.

Since the inception of servers, there's been one problem: every time you put out a fire you change the state of the virtual machine. Eventually, you don't know exactly what the server looks like and you can't recreate it, even though you know it works. (These virtual machines are referred to as snowflakes.)

In Kubernetes, new containers are immutable; they are created when there is a problem with the original state. So, you can be confident that you know exactly how the new environment is configured.

5. On-Demand Infrastructure.

Developers can create hybrid services and infrastructure on-demand from the self-service catalog. This gives control to developers to get the resources they need, yet allows operations to control the configuration of the services. Kubernetes follows open service and API standards so you can expose cloud services.

6. Environment consistency.

Build once, and deploy into production-like environments everywhere. Kubernetes allows you to build a golden image and use the exact same image for every single place you deploy your container. This gives you a consistent, production-like environment so it is the exact same whether you are on your local Windows or Mac development machine, a test server, etc. This helps you "shift left" so that you can see issues when you are in development instead of in production.

7. Continuous Delivery pipeline.

This is a series of automated steps to test code before it goes in production. Jez Humble says the role of Continuous Delivery is, "an automated process to prove to you a change is a bad change and it should not go into production." Continuous Integration (CI) means every change is tested. Continuous Delivery (CD) automates all the way to production.

How can you tell if you have fully implemented Continuous Delivery? Siamak says that the test is if someone walks in and says, "Can you go to production right now?" can you do it without breaking a sweat?

8. Zero downtime deployments.

When you have several deployments a day, you can't pull down production to deploy. You must have safe, rolling updates without disrupting the production traffic. Kubernetes helps with blue/green deployments so that you can set up a new environment and switch to the new one without downtime.

9. A/B Testing.

How can you evaluate proposed changes, such as changing copy or the color of buttons? A/B testing delivers different versions to different customers so you can get real-world test results. Kubernetes manages routing traffic to different versions. The same version with slight modifications are possible.

10. Cross-functional collaboration.

This is shared access to environments with granular control. Kubernetes goes beyond the silos so everyone has the same set of environments, but you can grant access to different roles and allow different roles to do different things. For instance, developers may be able to push to production, while Infosec may have view access, and QA may have access to live containers, but not building or deploying. The entire team can access production, but operations is the only one who can make containers.

The growing popularity of Kubernetes is undeniable. Luckily, with these 10 capabilities, Siamak has laid out a great path for us all to follow as they continue to not only make their way into the DevOps pipeline, but in many ways enable it.

Building and Managing Kubernetes with Kubernetes

Building and Managing Kubernetes with Kubernetes: Kubernetes as a declarative and portable system can be used to do many things in different ways.

Kubernetes as a declarative and portable system can be used to do many things in different ways.

At eBay we built a fleet management system based on k8s. Everything(server, subnet, OS, package and state) is declarative and can be modeled as CRDs in k8s, or referred to as a commit id in git from the objects. By running various controllers on top of these CRD objects, we use k8s to manage k8s, and the entire eBay data center. - Our system provisions hosts the same way k8s creates and manages pods. - We build k8s clusters with Salt. each host has a set of states defined in its salt CRD object. controllers pull states from git based on commit ids to apply. - We build both schedulers and deployment transactions to manage the k8s clusters for both config deployments and upgrades. This declarative, highly scalable, auto healing, and cloud native system is what we think can unify eBay’s fleet.
