Kubernetes Another Class - Sprint 3 (#CorePracticalSkills #Docker #Nginx #Minio #Longhorn)

⚓Kubernetes (Istio, Kiali, Jaeger, Cert-Manager) 🙇‍♀️Are you still hesitating? 🙋‍♂️Just trust me and follow along! I will take your skills to the ⭐next level.

Learn about the network multiplayer framework, also known as the other Unreal Engine. Learn the key concepts, inner workings, and optimization techniques you need to know when creating a network multiplayer game, then create a hack & slash type PvP battle game.

A new curriculum that incorporates the experiences of working developers using Docker, providing lectures that are different from existing textbooks and lectures. It starts from the fundamental question of why Docker should be used, rather than simple command usage.

⚓ Kubernetes (Prometheus, Grafana, Loki, OpenTelemetry) 🙇‍♀️ Are you still hesitating? 🙋‍♂️ Just trust me and follow along! I will take your skills to ⭐ another level.

Creating a simple Omok game using Unity and a C# server

Arduino? Coding? You don't need to know anything. Just invest a little bit of your free time and you'll find something amazing.

If you are a developer who deals with HTTP or want to become a developer but did not major in computer science and are weak in networking, gain lifelong knowledge with this one course!

This is not just a lecture for memorizing commands. It is a practical introductory course designed to help you intuitively understand the "flow" of technology—why containers emerged and the principles behind how Docker creates and runs images. Even those new to Docker will be able to explain for themselves "why containers are a necessary technology" after taking this course.

This is a course where you study core major knowledge such as network, multi-threading, and operating systems, and learn MMORPG technology by building a game server from scratch.

This course covers essential content that C# application developers with 0.5 to 3 years of experience must know.

Are you overwhelmed by AI-generated backend code and unsure where to look? Learn how to identify missing conditions in requests, APIs, data, concurrency, authentication, and caching—and what requirements to give the AI and what criteria to use when reviewing its output.

This lecture is written from the perspective of a non-major, so it may be lacking. However, as a non-major, I may know better what is difficult to understand.

This is Part 1 of a roadmap course that neatly organizes, in a short amount of time, the essential computer science (CS) knowledge you need to excel at development and data. This course has also been used for years as an in-house course at top companies in Korea. Based on 20 years of experience in the field, ranging from systems software to web and app development and data science, this course systematically and thoroughly covers the core concepts you need to excel at development and data—while keeping them easy to understand.

Network studies that you give up on every time because they are difficult and boring. Finish it once and for all with this textbook.

Deploy a Spring Boot SNS app to local Kubernetes, and automate deployments with GitHub Actions and Argo CD. Identify the causes of failures through metrics, logs, and traces, and review them based on AI analysis results.

Running MongoDB on Kubernetes is different from simply putting it in a container. There are many things you can only learn by dealing with storage, networking, permissions, and high availability firsthand. This course covers the entire process of configuring and operating MongoDB using the PSMDB (Percona Server for MongoDB) Operator in an AWS EKS environment. The goal is to directly build a production-ready configuration, from cluster setup to Replica Set configuration, backup, and monitoring.

This course will help you understand the value of IoT and how it changes our lives and society. You will learn the basics of IoT device programming, IoT device connection technology, big data analysis, and automation. You will understand digital transformation and its impact on businesses and society.

Have you ever wondered how real attackers carry out cyberattacks? BHPT is a practice-oriented comprehensive course where you use on-demand labs to conduct penetration testing on specific hosts from an attacker's perspective, learning the methodology of discovering, attacking, reporting, and responding to vulnerabilities.

If you want to work for a long time as a super developer who can handle the entire process of service development and operations alone, building a solid foundation in IT infrastructure knowledge is just as important as learning various programming languages!

This is a DevOps course based on practical experience in Silicon Valley. It goes beyond theory to cover content that can be applied immediately in the field. You will learn how to develop using Generative AI (Vibe Coding), set up CI/CD tools in a Kubernetes environment, and implement strategies to keep operating costs at $0. We will cover configuring a production environment without additional costs by running DB, Redis, S3, and batch jobs inside Kubernetes, and you will master building automated pipelines using GitHub Webhooks and Jenkins through hands-on projects.
