Bad deploy
On-call incident: a new version went out and the shop crashes on start. Restarting will not help. Roll back to the version that worked.
The ticket
Deploy bot: shop:2.0 deployed to prod-01 by jamie (new checkout!) 🚀
Support: …and the whole shop is down since. Please roll back!!
This is how it starts. The rest is up to you.
How it works
- 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.
- 02
Any correct way counts
We check the machine, not the exact words you typed, so you can solve it your way.
- 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 10, 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.
