DevOpsLesson is a free online platform that teaches DevOps hands-on. Instead of watching videos, you type real commands in interactive browser labs that check your work step by step. It covers the full DevOps toolchain — Docker, Kubernetes, Terraform, CI/CD, AWS, Git, and Linux — through structured tutorials, career roadmaps, and printable cheatsheets. Everything is 100% free and requires no account.
This repository is a curated index of everything on devopslesson.com, so you can navigate the entire learning path from one place.
- 🌱 Beginners starting from zero who want a clear, structured path into DevOps
- 💼 Job seekers preparing for DevOps, Cloud, or SRE roles and interviews
- 🔀 Developers & sysadmins transitioning into DevOps / platform engineering
- 🎓 Students who learn best by doing — running real commands, not memorizing slides
A recommended order to go from beginner to job-ready:
1. Linux fundamentals → 2. Git & version control → 3. Docker & containers
→ 4. CI/CD pipelines → 5. Kubernetes → 6. Terraform (IaC) → 7. Cloud (AWS)
Follow the guided DevOps Engineer Roadmap →
Structured, beginner-to-advanced tutorials for every core DevOps tool. Each track starts from the fundamentals and builds to production-ready skills.
| Track | What you'll learn | Start here |
|---|---|---|
| 🐳 Docker | Containers, images, Dockerfiles, Compose, networking, volumes | Docker Tutorial |
| ☸️ Kubernetes | Pods, deployments, services, kubectl, scaling | Kubernetes Tutorial |
| 🌍 Terraform | Infrastructure as code, providers, state, modules | Terraform Tutorial |
