Start the course

A complete, job-oriented path through DevOps: culture and DORA, YAML, Git, CI/CD pipelines with quality gates, artifact repositories, DevSecOps (SAST/DAST/SCA, supply-chain security), deployment strategies and progressive delivery, GitOps, agents/runners, observability, and internal developer platforms — built from production-grade lessons.

What you’ll be able to do

  • Build CI/CD pipelines as code with stages, quality gates and artifacts
  • Master deployment strategies — rolling, blue/green, canary, progressive delivery and feature flags
  • Implement DevSecOps — SAST/DAST/SCA, supply-chain security and policy-as-code
  • Run GitOps with Argo CD/Flux and scale agents/runners
  • Instrument delivery with DORA metrics and observability
  • Build an internal developer platform and be certification-ready

Prerequisites

  • Basic IT literacy, a terminal, and Git basics
  • A free GitHub/GitLab account and a cloud account for the hands-on labs

Who it’s for

Developers and sysadmins moving into DevOps, engineers building CI/CD and platforms, and people preparing for cloud DevOps or Kubernetes certifications.
