Building a container infrastructure environment using Kubernetes and Docker!

We organically connect and explain tools that support container infrastructure environments.

Kubernetes, Docker, Jenkins, and Prometheus/Grafana are representative tools required to build a container infrastructure environment, and have already become standardized in the market.
This book covers the overall process of reliably managing and operating containers, configuring CI/CD, and monitoring the system using the five tools mentioned above.
Let's understand the new infrastructure environment by configuring the container infrastructure environment.

Learn by coding with your own hands

If you simply learn the internal structure and commands of Kubernetes, it will be difficult to make it your own.
The fastest way to improve your skills is to learn concepts by directly following the source code and building an infrastructure.
So, we organized it in a hands-on manner in the order of 'code-code explanation' and included plenty of illustrations to make it easy to understand the concepts.
Through this book, we will solidify the fundamentals required to build and operate systems based on Kubernetes.

IT infrastructure technology know-how delivered by current experts

Current IT infrastructure experts provide step-by-step instructions on how to operate and manage diverse and complex IT infrastructure environments based on their own experience.
Let's thoroughly study the tips and notes inserted here and there and apply them to our work.
