Hello and welcome to the Linux Basics course. My name is Michael Forrester, and I’m excited to have you join us at KodeKloud.

Why Learn Linux?

Linux is the predominant server operating system worldwide. According to insights from Stack Overflow and other reputable sources:
  • Every flavor of Linux is widely utilized.
  • All 500 of the fastest supercomputers run on Linux.
  • 96.3% of the top 1 million websites operate on Linux.
  • Approximately 86% of all smartphones are powered by Linux.
In the cloud and DevOps landscape, many breakthrough tools were initially designed and deployed on Linux before expanding support to other operating systems. For example, containerization tools like Docker were Linux-exclusive for many years before Windows support was introduced. Similarly, automation and configuration management tools such as Red Hat Ansible require a Linux environment for installation and centralized control, even though they can manage Windows systems as remote targets. When it comes to container orchestration with tools like Kubernetes, the control plane (or master nodes) remains exclusively Linux-based. Current documentation confirms that there are no plans to develop a Windows-only Kubernetes control plane, even if Windows may be used as a data plane. For certification exams in Kubernetes, Red Hat Ansible, and other related technologies, having practical experience with Linux systems is crucial. Mastering Linux is a foundational step for anyone pursuing a career in DevOps, cloud, or infrastructure roles.

The Growing Demand for Linux Skills

The rapid rise of DevOps has created a significant need for professionals with strong Linux, cloud, and DevOps fundamentals. Almost every new job posting now demands a basic understanding of these areas. Engineers in organizations that leverage DevOps and cloud technologies need to be comfortable with:
  • Using the Linux command line
  • Managing system configurations
  • Maintaining security and networking practices in a Linux environment
This course features hands-on labs designed to help you practice and apply Linux fundamentals in real-world scenarios.

Course Structure and Learning Approach

Our course uses a story-driven format to contextualize important Linux concepts. Inspired by narrative styles in books like The Phoenix Project and The Unicorn Project, you’ll follow Bob, a new intern at Caleston Technologies. Bob faces challenges while building and deploying an application for a client demo, all while navigating a Linux-based environment across both his laptop and servers. Throughout the course, you will:
  • Follow Bob’s journey as he explores the Linux operating system.
  • Learn how to interact with the terminal and understand the shell, which serves as the gateway to the Linux kernel.
  • Study core Linux concepts that help you understand how systems operate.
  • Explore various package management methods used by different Linux distributions.
  • Gain confidence in navigating the command line, manipulating files, and using a variety of text editors.
  • Understand file-level security, configure permissions, and implement essential Linux security practices.
  • Troubleshoot networking connectivity issues effectively.
  • Configure storage options including disk formatting, mounting, and creating logical volume groups.
  • Set up custom applications to start on boot using SYSTEMD, the primary initializer for Linux services.
A person is sitting in front of a list of Linux topics, including shell, core concepts, package management, security, networking, and storage, with plants in the background.
Our lectures incorporate visualization, storytelling, and analogies to demystify complex topics. After each lecture, you will work on hands-on labs that challenge you with practical exercises, guided hints, and personal feedback.
All labs are executed directly in your browser, eliminating the need for local environment setup so you can start practicing immediately.
