If you’re a developer or sysadmin looking to break into DevOps, you’ve probably drowned in course catalogues promising “complete mastery” in a few weeks. Most of them fail for one simple reason: they teach tools in isolation instead of showing how they connect in a real pipeline.
This roadmap takes a different approach. Instead of watching hours of theory, you build one real project and layer in new tools only when you hit a wall that requires them — the same way engineers actually learn on the job.
Why Most Beginners Waste 80% of Their Time
Before the roadmap, it’s worth naming the traps that slow people down the most:
- Tutorial hoarding. Watching ten Kubernetes courses back to back feels productive, but it’s not the same as deploying a broken app and fixing it yourself.
- Skipping Linux and Bash fundamentals. Docker, Kubernetes, and CI/CD pipelines all assume shell fluency. Weak fundamentals here slow down every tool that follows.
- Jumping into Kubernetes before Docker is solid. Without a real grasp of containers, Kubernetes becomes memorization instead of understanding.
- Avoiding failure. The skill that actually gets tested in interviews is debugging under pressure — and you only build that by breaking things on purpose.
- No portfolio. DevOps hiring leans heavily on projects. A GitHub repo with real infrastructure code beats a stack of certificates almost every time.
The 30-Day Structure
The plan runs across six focus areas, in the order a real deployment pipeline actually flows:
Git & Linux → Docker → CI/CD → Cloud (AWS) → Kubernetes → Infrastructure as Code (Terraform)
Week 1: Linux & Git Foundations
The goal is simple — make the terminal and Git second nature. This means real bash scripting (not copy-pasted commands), file permissions, process management, and Git workflows beyond add, commit, push — rebasing, resolving conflicts, and understanding reflog.
Week 2: Docker & Containers
This is where the first real portfolio piece gets built. You containerize an actual application, write a clean Dockerfile with multi-stage builds, and get comfortable debugging containers when they fail — because they will.
Week 3: CI/CD Pipelines
Using GitHub Actions, you build a pipeline that tests, builds, and deploys your app automatically on every push. The most valuable exercise here isn’t building the pipeline — it’s breaking it on purpose and fixing it, which is exactly what interviewers want to hear about.
Week 4: AWS Cloud Basics
You move your containerized app from your laptop to the cloud. This week covers EC2, S3, IAM, and enough networking to understand security groups and VPCs — plus the unglamorous but important skill of reading a cost dashboard so you don’t get surprised by a bill.
Week 5: Kubernetes
With Docker fundamentals in place, Kubernetes becomes far less intimidating. You deploy your app to a local cluster, expose it with a Service, and practice the debugging skills that actually separate confident engineers from people who memorized kubectl commands.
Week 6: Terraform & Portfolio Polish
You convert your manually built AWS infrastructure into Terraform, add basic monitoring, and spend the final days polishing your GitHub repos and preparing interview stories — specifically, “what broke and how I fixed it” stories, which is the format most DevOps interviews actually run on.
What You’ll Have at the End
By day 30, the goal isn’t a stack of certificates. It’s a real, deployed application with:
- A clean, documented Docker setup
- An automated CI/CD pipeline
- Infrastructure running on AWS
- A working Kubernetes deployment
- Infrastructure-as-code via Terraform
- A handful of debugging stories you can talk through confidently in an interview
That combination — visible, working, explainable — is what actually gets DevOps candidates hired.
Setting Up Your Environment
Before Day 1, get your machine ready. Here’s what to install on each platform.
macOS Setup
Install Homebrew first — it’s the package manager you’ll use for everything else:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"Then install the core tools:
brew install git awscli kubectl minikube terraform
brew install --cask dockerOpen Docker Desktop once from Applications to finish setup, then verify everything works:
docker run hello-world
git --version
kubectl version --client
terraform -versionmacOS Terminal runs on zsh by default, so Linux/Bash practice from Week 1 works natively — no VM required. One thing to check: Apple Silicon (M1/M2/M3) Macs sometimes need --platform linux/amd64 when pulling Docker images built for Intel.
Windows Setup
The smoothest path on Windows is to install WSL2 (Windows Subsystem for Linux) first, since it gives you a real Linux environment for Week 1’s Bash practice instead of trying to translate every command to PowerShell.
wsl --installRestart when prompted, then open the Ubuntu app that installs by default. From inside WSL2, install Git and the rest of the tools the same way you would on Linux:
sudo apt update
sudo apt install git -yFor Docker, install Docker Desktop for Windows from docker.com and enable WSL2 integration in Settings → Resources → WSL Integration. This lets you run docker commands directly from your Ubuntu terminal.
For the remaining tools, use a package manager like Chocolatey (or install inside WSL2 with apt, which tends to be more reliable for this roadmap):
choco install awscli kubernetes-cli minikube terraform -yVerify everything from your WSL2 terminal:
docker run hello-world
git --version
kubectl version --client
terraform -versionDoing all your Days 1–30 work inside WSL2 rather than native Windows/PowerShell will keep your commands consistent with what you’ll use on the job — most production DevOps work happens on Linux regardless of what your laptop runs.
Final Thought
DevOps isn’t a checklist of tools to memorize; it’s a set of habits around automation, reliability, and recovering quickly when things break. Thirty focused days won’t make you a senior engineer, but they will get you past the biggest hurdle most beginners never clear: having something real to show, and the scars to prove you understand it.
