Challenge Details

Ansible is one of the most in-demand automation tools in DevOps — but most courses teach you the theory without giving you a real environment to practice in. This course is different: every lesson runs in a local Docker-based lab you set up on your own machine, no cloud account needed.

You start from scratch and finish with a production-ready Ansible project — complete with encrypted secrets, multi-environment deployments, team access controls, and a web UI to trigger playbooks from a browser.

What you'll learn:

• Set up a real Ansible lab using Docker containers as managed nodes — fully local, no cloud required
• Understand Ansible's agentless architecture and how SSH-based automation works under the hood
• Write inventory files with host groups and per-host variables for structured infrastructure
• Run ad hoc commands and master core modules: ping, package, copy, command, shell, and more
• Write playbooks that orchestrate tasks across multiple hosts in a defined order
• Use variables, facts, conditionals, loops, handlers, and templates for flexible automation
• Organise playbooks into reusable Ansible roles with a professional directory structure
• Manage separate dev and prod inventories within a single project
• Encrypt secrets with Ansible Vault using AES-256 — passwords, API keys, and private data stay safe in Git
• Use Vault IDs to apply different encryption passwords per environment
• Onboard and offboard team members safely using per-developer SSH keypairs
• Protect your Git repository with .gitignore rules, pre-commit hooks, and detect-secrets scanning
• Validate playbooks before every production run with ansible-lint and dry-run mode (--check --diff)
• Run Ansible from a browser with Semaphore UI — audit every run, schedule jobs, and manage team permissions without SSH access

How the course is structured:

The course follows a single Acme company scenario from start to finish. Each lesson introduces one concept, applies it in the lab immediately, and builds on the previous one. You won't jump between disconnected examples — the playbooks, inventory, and project you build in Lesson 1 are the same ones you secure with Vault in Lesson 10 and run through Semaphore in Lesson 17.

Requirements:

• A Mac running macOS (the lab uses Docker Desktop for Mac)
• Comfort with the terminal and basic Linux commands (cd, ls, cat, ssh)
• No prior Ansible experience needed

Who this course is for:

• Developers who want to automate server configuration and deployments
• Sysadmins and infrastructure engineers moving from manual processes to infrastructure-as-code
• DevOps engineers learning Ansible for team-based environments
• Anyone who has tried Ansible from the docs and wants a structured, hands-on path

💡 This is an interactive, text-based course. We build our material this way because reading and doing is simply the most effective way to master engineering tools.

Video tutorials make it easy to drift off, lose focus, or fall into passive watching. In contrast, a text-first approach keeps you active: you control the pace, scan code without scrubbing timelines, build precise mental models, and immediately apply commands in hands-on environments
