The ticket

Monitoring: ALERT: shop-api on :8080 not responding (5 checks failed).

Dev (Ana): I recreated shop-api to change an env variable. It worked on my machine… the database is fine, I checked.

This is how it starts. The rest is up to you.

How it works

  1. 01

    A machine of its own

    You get a simulated computer, set up for this challenge. Your own machine is kept aside and comes back afterwards.

  2. 02

    Any correct way counts

    We check the machine, not the exact words you typed, so you can solve it your way.

  3. 03

    Learn why

    When it works, a short lesson explains what was wrong and how the real tool behaves.

Questions

When does it open?

When you finish Level 8, the level that teaches what you need.

What if I get stuck?

Ask for a hint. Hints cost a little XP, and the last one tells you what to type.

Can I play it again?

Yes, as often as you like. Your best result is the one we keep.

Is this a real Linux or Docker?

No. It is a simulation that answers like the real tools, so nothing can break and nothing runs on your computer.
