Configuration Management Automation Tool - Ansible

Let's learn how to automate various environments (Linux🐧, Windows📱, and network📶 systems) through ensembles. 🥇 Through this, we can manage various systems by unifying them into ensembles. And we will learn how to enhance🧑‍🔧 the ensemble code we have written. In other words, we will learn how to write code to run more effectively🏃 faster.

I don't really understand the concept of automation.

What you will gain after the course

  • Automation and configuration management using Ensemble

  • Setting up a practice environment on various operating systems

  • Write and optimize playbooks

  • Security and Performance Tuning

  • Network System Management through Real Cases

  • Understand the latest features of Ensemble

Ansible: The Best Tool for System Automation

💡 Things to know before registering for a class

  • Ansible is a system configuration management tool. Therefore, it's not suitable for modifying containers (often called Docker). Because containers are immutable, the training environment will be a virtual machine (VM) suitable for the Ansible environment.
  • Additionally, because Ansible is a system configuration management tool, it's not well-suited for resources that are deployed on demand (primarily in the cloud). You can learn more about this in the free preview of [(Section 15-1) Ansible vs. Terraform and the Future of Ansible] . For a more detailed example, please refer to [(Section 24-1) Upgrading Kubernetes Versions with Ansible] .
  • The ensemble version is an older version, but I am maintaining the current content because there doesn't seem to be any major issues with the content itself that deals with ensembles.
  • If you find the above content satisfactory and find the current course list helpful, we recommend that you proceed with the course.

📖 In this lecture

In [Basics] , we will briefly look at the installation and execution of the ensemble.
In [Application] , we'll implement automated management of various systems beyond CentOS, which we covered in the basics, through Ansible. This will allow us to create a unified management system.
 ( https://github.com/sysnet4admin/_Lecture_Ansible.adv )
[Optional] This covers `What's New in Ansible 2.5` and `Configuring NX-OSv Lab for Network Practice`, and is a reference level content that you can listen to if necessary.
( https://github.com/sysnet4admin/_Lecture_Ansible.Update1 )
In [Advanced] , we'll take our simple code and make it more structured, efficient, and reusable. Now, beyond functional functionality, we'll explore the crucial, yet crucial, aspects of protecting sensitive information and improving performance.

CNCF Ambassador | Cloud Native Engineer

  • • Linkedin

  • • Youtube

    At Megazone, I serve as a Tech Evangelist and a member of the CoE (Center of Excellence), focusing on Kubernetes and container infrastructure. My primary role involves modernizing and optimizing the costs of the Kubernetes environments used in the company's SaaS products, while also providing Tech Advisory and Container Architecture Design support for external clients. As a Global Ambassador for the Cloud Native Computing Foundation (CNCF), I contribute to the widespread adoption of cloud-native and AI-native technologies. Additionally, I serve as an organizer for the 'IT Infrastructure Engineer Group' and remain active as an open-source contributor.
    I enjoy sharing knowledge, which has led me to teach courses on Ansible and Kubernetes on platforms like Inflearn and Udemy. Believing that knowledge truly gains meaning when documented, I have authored books such as "Kubernetes/Docker for Building Container Infrastructure Environments," "Elegant Ansible," and "Practical Python Programming for System/Network Administrators." I also frequently contribute articles to online platforms like YojeumIT.
