TenkaCloud
Open-source cloud competitions on real AWS accounts
TenkaCloud is an Apache-2.0 platform for hands-on cloud competitions. It provisions isolated environments for each team, supports self-paced Challenges and continuously scored Battles, and brings access, scoring, fault injection, leaderboards, and cleanup into one operator workflow. Start with a no-signup browser quest, run locally with Docker, or host an event on your own AWS account. The open problem catalog and authoring skill let teams create and reuse their own drills.
Hi Product Hunt — I’m Susumu, creator of TenkaCloud.
I built it because most cloud training stops at a working template or a scripted lab. Running a real multi-team exercise is a different problem: each team needs an isolated environment, safe access, repeatable provisioning, scoring, hints, fault injection, a leaderboard, and reliable cleanup.
TenkaCloud brings those pieces together as Apache-2.0 OSS. It supports two formats:
• Challenge: self-paced, flag-based drills
• Battle: live exercises scored continuously from the actual state of each team’s service
The first quest takes about three minutes and needs no signup. After that, you can try local Docker mode or deploy TenkaCloud Lite into your own AWS account.
I also published the full authoring and operating path as a free English book: https://leanpub.com/build-your-o...
I’d especially value feedback from SRE, platform engineering, cloud security, and enablement teams: what scenario would you want to run as a competition?
