Challenges
Blind by Design This adventure was created by Simon Schrottner, CNCF Ambassador and maintainer of OpenFeature and JUnit Pioneer. Simon helps teams release faster and with more confidence through open standards, feature flagging, and the communities that make both possible. A familiar face at KubeCon EU, Devoxx, ContainerDays, and meetups across Europe. 🏗️ Builders Echoes Lost In Orbit Welcome to the first challenge in the OffOn Challenge series! Your mission: restore interstellar communication by fixing a broken GitOps setup. This is a hands-on troubleshooting exercise using Kubernetes, Argo CD, and Kustomize. ⚖️ Lex Imperfecta The Roman Republic has built a sophisticated legal system to protect its citizens — but the laws were written in haste, and the exceptions were written too generously. Policies go unenforced, the wrong citizens are exempt, and something has slipped through the gates unnoticed. As a newly appointed Praetor, your mission is to restore order before chaos takes hold. Building CloudHaven Welcome to the second adventure in the OffOn Challenge series! Your mission: modernize CloudHaven’s infrastructure from manual provisioning to a self-service platform. This is a hands-on journey through infrastructure as code with OpenTofu and GitHub Actions. The AI Observatory Welcome to the third adventure in the OffOn Challenge series! Your mission: investigate a mysterious bandwidth anomaly at a remote research station by instrumenting its AI system. This is a hands-on journey through AI Observability with OpenTelemetry, OpenLLMetry, and Jaeger. Dead Reckoning The Grand Fleet’s commission office is buried in complaints. Manifests are filed but nothing comes of them. Vessels that do sail arrive at port with the wrong cargo, and no one along the route can explain why. As the fleet’s engineer, your mission is to restore order from keel to quayside and find out what the records are hiding.
