Survive the Reboot

Give a container a restart policy so daemon restarts don't take it down.

A beginner Docker challenge worth 3 points. Solve it hands-on in a real Docker environment in your browser - no local setup, no fake shells.

The Challenge

Scenario: Last night the Docker daemon restarted and the worker container never came back — nobody noticed until the queue backed up for six hours.

Tasks:

• Recreate worker (image alpine, command sleep infinity) so it restarts automatically after daemon/host reboots
• …but stays down when an engineer deliberately stops it (pick the right policy!)

Commands to learn: docker run --restart, docker inspect

Run check when done.
