What you will learn

  • Automate repetitive tasks with Bash scripts, pipes and exit codes.
  • Use Git branching and pull requests, and resolve a merge conflict without losing work.
  • Containerize an application with a Dockerfile and explain layers and build caching.
  • Design a CI pipeline (build, test, scan, deploy) that fails fast and is cheap to run.
  • Describe Pods, Deployments and Services, and perform a rolling update with a rollback plan.
  • Define environments as code and review a plan diff before applying it.
  • Instrument a service with metrics and logs, define an SLO and compute its error budget.
  • Add security gates (secret scanning, dependency and image scanning) to a pipeline.

How you are assessed

DevOps is judged on reliability and repeatability: quizzes check your reasoning about pipelines and failure, and the shell lab proves you can script a task that gives the same answer every time.

The delivery toolchain

Shell, Git, containers and your first pipeline.

0/4
  1. 1.Linux & Shell — The DevOps Cockpit

    Command line, bash scripting, cron jobs, file permissions, and process management. DevOps engineers live in the terminal — Linux is the operating system of the cloud.

  2. 2.Git for DevOps — Workflows & Versioning

    Branching strategies (GitFlow, trunk-based), pull requests, merge conflicts, tagging releases, and monorepos. DevOps starts with solid version control practices.

  3. 3.Docker — Containers for DevOps

    Containers, Dockerfiles, images, volumes, networking, and docker-compose. Docker changed software deployment forever — it's the foundation of all modern DevOps.

  4. 4.CI/CD Pipelines — Automated Delivery

    GitHub Actions, GitLab CI, Jenkins — automate testing, building, and deploying on every commit. CI/CD is the core practice of DevOps: ship code faster and safer.

Run it in production

Kubernetes, environments as code and observability.

0/3
  1. 5.Kubernetes — Orchestrating Containers

    Pods, deployments, services, ingress, ConfigMaps, Secrets, Helm charts, and cluster management. Kubernetes is the industry standard for container orchestration at scale.

  2. 6.Infrastructure as Code — Environments in Git

    Terraform for provisioning infrastructure, Ansible for configuration management. Write infrastructure like software: version it, test it, and deploy it automatically.

  3. 7.Monitoring & Observability — Seeing Production

    Prometheus, Grafana, ELK Stack (Elasticsearch, Logstash, Kibana), and distributed tracing. If you can't observe it, you can't fix it. Monitoring is what separates DevOps from ops.

Secure delivery

Shift security left without slowing teams down.

0/1
  1. 8.DevSecOps — Security Built In

    Shift security left: SAST/DAST scanning in CI, secrets detection, container image scanning (Trivy), and compliance as code. Security is now a shared DevOps responsibility.

Run a real example

This is the kind of code you will write. Run it, then change it and run it again.

JavaScript (Node.js)

Every extra nine cuts the downtime you can afford by 10×, which is why SLOs drive how you deploy. Try a 7-day window.
