Hardening a Container Image
By Techworth Labs
Take a bloated application image that runs as root and rebuild it as a minimal, non-root, reproducible image, measuring the vulnerability count at every step.

What to Expect
- Environment: describe the machine and what is installed on it.
- Access: how the learner connects, and that credentials are per-session.
- Progress: work is not saved once the lab ends.
What are hands-on labs?
A lab is a real environment, not a simulation. You get a live machine with the tooling already installed, a task taken from production work, and root access to take it apart. Nothing is mocked, nothing is multiple choice. It either works or it doesn't.
Real tooling
The same commands you would run at work, on a machine that is already set up for them. No screenshots, no sandboxed toy version.
Break it freely
Everything is disposable. When the clock runs out the environment is destroyed with everything in it, so there is no reason to be careful.
Useful on Monday
Built by engineers who run these systems in production. Skills you can apply to your own stack the same week, not exam preparation.
