Copy In, Copy Out

Move files between a running container and the host with docker cp.

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: The reports container is redeployed tonight. Before that:

Tasks:

• Back up /var/reports/q2.csv from inside reports to /root/backup/q2.csv
• Hotfix the config: copy /root/fix/config.ini INTO the container at /etc/app/config.ini (create /etc/app inside it first with docker exec)

Commands to learn: docker cp (both directions), docker exec mkdir

Run check when done.
