From Zero CLI to
Production DevOps
Learn Linux, Git, GitHub Actions, CI/CD, Docker, and Kubernetes step-by-step. Designed with rich interactive diagrams for complete beginners.
Your 13-Step Roadmap to DevOps Mastery
A structured, zero-confusion journey designed so every concept naturally unlocks the next one.
Start with These Core Courses
Fully interactive lessons packed with terminal commands, analogies, and downloadable workflows.
Linux Command Line for DevOps
Master the terminal, essential bash commands, file manipulation, permissions, process management, and SSH to navigate servers with confidence.
Git & GitHub Fundamentals
Learn version control from the ground up: staging, commits, branches, merges, remotes, pull requests, and real-world branching strategies.
GitHub Actions Automation
Automate testing, linting, building, Docker container publishing, and deployment workflows triggered directly by Git events.
Docker & Container Fundamentals
Package applications into lightweight, reproducible containers. Master Dockerfile instructions, layer caching, image optimization, and volume mounts.
Kubernetes (K8s) Basics
Step into the standard enterprise container orchestrator: Pods, Deployments, Services, ConfigMaps, Ingress, and self-healing systems.
Terraform & Infrastructure as Code (IaC)
Master declarative infrastructure automation: HCL syntax, providers, state locking, reusable modules, multi-environment setups, and CI/CD plan/apply workflows.
Engineered specifically for Beginner Confidence
Stop drowning in confusing cloud documentation. Learn by building mental models that actually stick.
From Absolute Zero to Fluency
Every concept is taught in plain English with relatable analogies (like video game checkpoints and factory lines). No gatekeeping.
Interactive Flow Diagrams
Understand Docker architectures, Kubernetes component relationships, and GitHub Actions pipelines visually with React Flow & Mermaid.
Real Terminal Commands with Context
Don't just memorize commands. Learn when, why, and how to use every command when debugging real staging and production servers.
Common Mistakes & Pitfalls Included
Every lesson has dedicated 'Common Pitfalls' callouts so you don't spend hours debugging cryptic error messages or permission denied traps.
End-to-End Capstone Deployment
Complete a real GitOps deployment pipeline: Git Push → GitHub Actions → Docker Build → GHCR → K3s Kubernetes cluster rollout.
100% Free & Open For Everyone
No paywalls, pay-per-module tricks, or subscription models. Complete high-quality DevOps education accessible to all developers.
