What's new in Ansible version 2.5

As an ambassador for the Cloud Native Computing Foundation (CNCF), I have given talks at KubeCon on topics such as Kubernetes security and policy, the scheduler, and Gateway API. I also serve as an ambassador for the Agentic AI Foundation (AAIF), where I present findings from hands-on research and measurements of AI agents, LLMs, MCP, and AGENTS.md in Kubernetes environments. This course includes Korean-language recordings of talks I have given in English at international events such as KubeCon, Open Source Summit, MCP Dev Summit, and AGNTCon + MCPCon, and I add each recording as it becomes available.

I’ll share the preparation methods I learned while earning Linux Foundation certifications directly, including Kubernetes certifications (KCNA, KCSA, CKA, CKAD, and CKS), the Prometheus certification (PCA), and the MCP certification (MCPA).

You can learn how to use Kubernetes in practice by first understanding its components through diagrams, then writing YAML and deploying it directly with kubectl. The course also expands on the content of the bestseller *Kubernetes/Docker for Building Container Infrastructure Environments*, covering advanced topics such as networking, volumes, and cluster management.

It covers the fundamentals that Kubernetes beginners need from the very start. This makes it easy to understand Kubernetes’ architecture without working with code, using a hands-on environment installed directly on your personal PC.

Let’s learn how to automate various environments (Linux🐧, Windows📱, and network📶 systems) with Ansible. 🥇 This allows you to manage various systems consistently using Ansible. We’ll also explore how to enhance🧑‍🔧 the Ansible code you write—in other words, how to write code that runs more effectively and quickly🏃.
