Challenge type

🖥️ Lab Configuration

Each hack challenge should include one Docker File Upload widget (canvas) and this panel. The student lab widget reflects that Docker lab in the browser — same ports and services you list below, with a session time you choose (max 60 minutes).

Fly.io image tag

In-browser lab (Fly): Start Lab spins up the VM from this image tag. Until you deploy your own zip to Fly and paste its registry tag here, Zip + Build sets the tag automatically. Not :latest. Terminal = https://htb-lab-test.fly.dev (Fly cloud). Target App = same host :8080 (not localhost). Rebuild zip after Dockerfile port changes.

Download zip (widget above): separate path — students download and run Docker locally. Upload/clearance does not auto-switch this Fly image yet. See interactive lab guide.

Session duration (minutes)

Maximum 60 minutes per in-browser session. Set any shorter value (minimum 5). Students see this limit on the lab widget.
