Rescue Docker healthcheck hardening
Extreme DevOps Basics arena: container health probes, startup grace, exit codes, and observable failure modes
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: devops-easy-docker-healthcheck
A container restarts constantly because the healthcheck is too fragile during warmup. You are working inside a deployment operations lab, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply container health probes, startup grace, exit codes, and observable failure modes in a deployment operations lab while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates container health probes, startup grace, exit codes, and observable failure modes
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
Clear the route first
You can read the mission brief, but the editor, hints, tests, and submit flow stay locked until progression or plan access catches up.
