Overview

DevOps is a set of practices that shortens the path from code to production while keeping releases reliable. It combines culture, automation and measurement.

You will version code with Git, automate builds and tests with GitHub Actions, package apps in Docker containers, and deploy to cloud platforms.

What you will learn

  • Collaborate with Git branches and pull requests
  • Automate builds, tests and deployments with CI/CD
  • Containerise apps with Docker and Compose
  • Manage infrastructure as code and plan rollbacks

Prerequisites

None — this track starts from the very beginning.

Docker

docker build turns a Dockerfile into a layered image; docker run starts containers from it.

Code example

Expected output
Every commit is built and tested automatically; passing changes flow to production through the same repeatable pipeline.

Common interview questions

Frequently asked questions

Is DevOps a job title or a practice?
Both terms are used. At heart it is a practice; many companies also hire DevOps or platform engineers to build the tooling.
