Reviews from Early Learners
What you will learn!
Core Concepts of Kubernetes
Cloud app development and deployment process
Principles of Microservice Architecture
Google Cloud Code (SDK)
Learning Kubernetes for the first time, easy with practice!
Standard for cloud/server environments
Getting the Kubernetes Basics Right
Kubernetes: The Beginning of Cloud/Server App Development
In this course, you'll learn how to develop and deploy applications in a Kubernetes environment, and understand the core concepts of Kubernetes and the design principles of microservices architecture (MSA).
Cloud/server environments are complex and require extensive knowledge. Furthermore, they are constantly changing and evolving, making them challenging for beginners.
Kubernetes (K8s) is arguably the standard for cloud/server environments . Major cloud providers like AWS, Google, and Microsoft support Kubernetes, making it the most essential foundation for cloud/server development.
Learning Kubernetes Through Practice by Minikube
Minikube allows you to configure a Kubernetes environment on your PC. This means you can study cloud/server development even without connected servers.
In this course, we'll configure a Kubernetes environment with Minikube and develop a simple example application. Through hands-on practice, we'll understand the core concepts of Kubernetes and lay the foundation for becoming a cloud/server developer!
For those of you new to Kubernetes

Detailed Curriculum 📚
Entire curriculum
Learning Objectives
In this lecture, we'll develop a counter app consisting of three microservices and deploy it on Kubernetes. This will help you understand core Kubernetes concepts and the fundamental principles of microservice architecture.
- The ingress API gateway forwards requests to services.
- The web-inc service handles count increment requests (INC).
- The web service processes requests (GET) for the count value.
- The redis service stores the count value.
Section 1
Handling Kubernetes with kubectl commands
We will learn how to create and manage Kubernetes components using kubectl, the Kubernetes command tool.
- Deployment is done using the nginx image, which is a web server.
- Expose the nginx pod as a service.
- Create an ingress API gateway and connect the service.
Section 2
Developing Node.js Apps on Kubernetes
Develop a simple web service and deploy it to Kubernetes. Learn how to specify and manage Kubernetes components using YAML files.
- Develop web services with the Node.js HTTP module.
- Create (build) a Docker image to deploy the developed web service.
- Deploy the created image as a deployment.
- Exposes the pods created by the deployment as a service.
This course covers the basic process of developing cloud/server apps in a Kubernetes environment (development - image build - deployment). The source code for Section 2 is available on GitHub.
Section 3
Creating a Counter App
We develop a counter app that stores the count value as a file in a persistent volume and serves it.
This tutorial demonstrates how to automate builds and deployments using Google Cloud Code. The source code for Section 3 is available on GitHub.
Section 4
Completing the Counter app with a Redis DB
We will implement the final structure of this lecture, which consists of a web-inc service that handles count increase requests, a web service that returns the count value, and a redis service that stores the count value in a Redis DB.
- Stateless web and web-inc services that do not require state storage are configured as deployments.
- Redis services that need to store state are configured as statefulsets.
- Set up Redis DB in master-slave structure.
- Set up an ingress API gateway that routes services based on requests.
- We also set up an autoscaler to automatically adjust the number of pods based on CPU load.
The source code for Section 4 is available on github.
Q&A 💭
Q. Is there anything I should know before attending the lecture?
- This course is hands-on, so no special prior knowledge is required.
- However, basic knowledge and experience in computers/networks and programming may be required.
- Just follow along slowly.
