Welcome to the intermediate level of the Echoes Lost in Orbit challenge adventure! Your mission: enable communication for a new alien species by fixing a broken progressive delivery system. This is a hands-on troubleshooting exercise using Kubernetes, Argo Rollouts, and Prometheus.
The entire infrastructure is pre-provisioned in your Codespace — Kubernetes cluster, Argo CD, Argo Rollouts, Prometheus, and sample app are ready to go. You don’t need to set up anything locally. Just focus on solving the problem.
The Challenge
The Intergalactic Union welcomed a new species: the Zephyrians 
. The communications team attempted to deploy their language files using a progressive delivery system with automated canary deployments, but the rollout is failing. The Zephyrians are still waiting to communicate with the rest of the galaxy. Your mission: debug the broken rollout and bring the Zephyrians’ voices online.
What you’ll learn:
- How to write PromQL queries to monitor application health
- How progressive delivery reduces deployment risk with automated validation
- How to debug and fix broken canary deployments
- How Argo Rollouts and Prometheus work together to
make data-driven deployment decisions
Objective:
By the end of this level, you should have:
- Pod info version 6.9.3 deployed successfully in both staging and production environments
- Rollouts automatically progress through canary stages based on health metrics
- Two working PromQL queries in the
AnalysisTemplatethat validate application health during releases - All rollouts complete successfully
Deadline: Wednesday, 24 December 2025 at 09:00 CET
You can still complete the challenge after this date, but points will only be awarded for submissions before the deadline.
