Fix It Live

Rename a container and change its limits with ZERO downtime.

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: A live-traffic container is named webapp-prod-final-v2-REAL, has no memory limit and no restart policy. You may not stop or recreate it — uptime must be preserved (the checker verifies it's the same container!).

Tasks:

• Rename it to payments-worker
• Apply --memory 256m (with matching --memory-swap) and restart policy unless-stopped — using docker update

Commands to learn: docker rename, docker update

Run check when done.
