Diagnose the Crash Loop

Read the logs of a restarting container and fix its missing config.

A intermediate Docker challenge worth 10 points. Solve it hands-on in a real Docker environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: PagerDuty is screaming: orders-api shows Restarting in docker ps. It dies instantly, over and over.

Tasks:

• Find out why it's crashing (docker logs orders-api — also visible in the browser panel's Console tab)
• Recreate the container fixed — same name, same image (orders-api:v1), keep --restart on-failure
• The database it needs is at db.internal

Commands to learn: docker logs, docker run -e, docker inspect

Run check when done.
