Sample output, nothing runs here. In a course, these checks run against your own container.
How a course works
Every chapter follows the same loop, so you always know what comes next.
- 01
Read
Short lessons explain one idea at a time, with the exact commands and config files you will use. A quiz checks you understood before you move on.
- 02
Practise in a real container
Each lab opens a terminal on a fresh Linux container. Break things, start over, try again. Nothing to install on your machine.
- 03
Prove it with graded checks
Lab steps are checked against the real state of your container, so a pass means the work is done. With Pro you can sit a proctored exam and earn a certificate anyone can verify.
