Kubernetes Tutorials For Beginners: 28 Comprehensive Guides

Kubernetes Tutorials For Beginners:

In this blog, I have covered a list of kubernetes guides that can help you learn Kubernetes. This Kubernetes tutorial for beginners series is focused on kubernetes basics objects and associated tooling around them.

Before you get started with Kubernetes, it is essential to understand the concept of containers. So if don’t have a basic understanding of containers, I would suggest learning containers basics and then starting with Kubernetes. You can check out my article on “what is docker” to understand the whole concept of containers.

What is Kubernetes?

As the definition says, Kubernetes or k8s is an open-source orchestration and cluster management for container-based applications.

Official kubernetes (k8s) website says,

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery. Kubernetes builds upon 15 years of experience of running production workloads at Google, combined with best-of-breed ideas and practices from the community.

In simple words, kubernetes make it easy to manage containers on multiple hosts. Also, it makes the container deployment so easy using a declarative YAML file. You specify how you want the container to be deployed, and Kubernetes takes care of it by reading the information provided in the YAML.

Why do we Need Kubernetes?

Before we get into a detailed list of beginners tutorials, I would like to give you two examples of why we need Kubernetes.

The first question when it comes to Kubernetes or a container orchestrator is why we need it. Let’s understand it from two examples.

Example 1: Container Deployments

Let’s say you have a couple of java applications. You can package it into a container and run it on a server containing docker. For this scenario, there is no complexity.

You package your application into a Docker image using Dockerfile and expose a port on a host for the external world to access it.

The only downside is that it is a single point of failure as it is a single server. So you need an efficient mechanism to handle a single point of failure.

This is why you need a container clustering & orchestration tool like Kubernetes to scale applications on-demand and to withstand single node failures.

Example 2: Microservices Deployment/Orchestration

Now, let’s say, you have a big application that is composed of microservices (APIs, UI, user management, credit card transaction system, etc). All these microservice components have to talk to each other using REST or other protocols.

As the application has many components or microservices, we cannot pack all the services into one server or a container. The application has to be decoupled and each microservice should be deployed and scaled on its own. This makes application development and deployment easier and faster.

The complexity lies in networking, shared file systems, load balancing, and service discovery in this scenario. Here is where kubernetes comes in to picture. It helps in orchestrating complex processes in a manageable way.

Using kubernetes, you just have to worry about your application development and deployments. All heavy lifting like networking, service to service communication across nodes, load balancing, resource scheduling, scalability, and high availability are taken care of by Kubernetes.

Kubernetes Tutorials For Beginners

I have listed a list of kubernetes beginners tutorials that you can use to get started with kubernetes. This is a growing list.

Note: Kubernetes is an open source tool with constant updates to features. There is change where a guide might have a older version of APIs or workflows used. I try to keep all the guides updated. If at all, if you face any issue, please drop a comment so that I can be aware of the update and make the changes accordingly.

I have categorized the tutorials into multiple segments. So let’s take a look.
