The Practical DevOps Roadmap for People Who Hate Cert Cramming
Certs prove you can pass a test. Employers want proof you can deploy and run things. Here's a roadmap built entirely around skills you can demonstrate.
There's a whole industry built on DevOps certifications, and they're not worthless — but they're a poor first move. Memorising a vendor's service names doesn't teach you to run software, and an exam badge is weaker proof than a thing you actually deployed. Here's a roadmap built around demonstrable skill instead.
Own the terminal
Start on Linux until the command line is second nature. Files, permissions, processes, SSH, logs, editing config by hand. This is the bedrock, and no cert substitutes for being comfortable here.
Containerise something real
Take an app and put it in a container. Learn images, volumes, networking, and Compose by running a real multi-service setup (app + database). Now you understand the unit modern infrastructure is built from.
Put it on the internet, securely
Get it running on a server behind Nginx with HTTPS. The skill of taking something live — and keeping it up — is exactly what the cert can only describe.
Automate the boring parts
Once you do deployments by hand, automate them. That's all CI/CD really is: scripting the steps you already know. Starting from manual understanding makes pipelines obvious instead of magical.
Then, if you want, get the cert
A certification on top of real, deployed projects is a nice signal. A certification with nothing behind it is a red flag to anyone who interviews well.
By now you'll pass the exam more easily anyway, because you've done the things it asks about.
The principle
Optimise for proof, not paper. A handful of projects you can show — running, in production, that you can explain — beats a wall of badges every time.
Stop reading, start building
This pairs with a hands-on BytExplorer course — do it on your own machine and actually keep the skill.
