Target time
27m
A service rolls into CrashLoopBackOff only after the second replica starts. You are working inside a deployment operations lab, and the arena only clears when the result is safe, deterministic, and explainable.
Learning objective
Learn to apply pods, logs, events, probes, resource limits, and rollout history in a deployment operations lab while explaining the invariant, safety constraints, and hidden edge cases.
Mission order
kubectl snapshots include pods, describe output, previous logs, deployment YAML, and events. Implement the direct solution first, then document the one edge case that can break it. Submit the solution plus enough reasoning to pass hidden edge cases.Visible checks
uses safe command composition
Expected: deterministic command sequence
handles ordinary filenames
Expected: stable output
Clear requirements
- Demonstrates pods, logs, events, probes, resource limits, and rollout history
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
Secure validation contract

BASH SCRIPTING
Complexity target
Linear scan over simulated files/log rows with deterministic output
Simulated lab
3 files/directories, allowed commands: awk, cat, cut, du, df, find, grep, head
Workspace
Terminal lab
Simulated secure terminalhost isolated
Test Results
Run the visible checks when your first pass is ready.
Clear Protocol
1Read the scenario and restate the expected output shape.
2Run visible checks before chasing hidden edge cases.
3Use Genie for one nudge if stuck, then explain the invariant.
4Submit only when the result is deterministic and safe.
