DevOps & SRE Mastery
Free, hands-on learning paths, guides and tutorials for engineers who run production systems. Learn by building, break things on purpose, and check what you know with quizzes.
Learning paths
Two structured routes. Each one has phases to follow, labs to build, exercises and a quiz with explanations.
SRE From Scratch
From Linux and networking to monitoring, incident management and on-call readiness.
DevOps Training Path
Git, Docker, GitLab CI, Terraform, Ansible, Kubernetes and delivery metrics.
Guides and tutorials
Setup guides and copy-and-run procedures taken from day-to-day operations work.
VS Code for SRE and DevOps
Extensions, settings and GitLab integration on macOS.
iTerm2 setup for SRE
A terminal environment built for operations work.
Essentials guides
Docker, Kubernetes, Terraform, Ansible, Git for teams and a GitLab CI reference.
Step-by-step tutorials
Multi-stage Docker builds, a first CI pipeline, Terraform without a cloud account, and debugging CrashLoopBackOff.
Test yourself
Ten topics with ten questions each. The order is shuffled every time, and every answer links to its source.
How it works
Built around practice rather than slides.
Hands-on labs
Every path has labs you run on your own machine or a free tier.
Quizzes with explanations
100 questions in 10 topics. Each answer explains why it is right and links to the official source.
Copy-and-run commands
