Clean up all Docker resources

Docker: Cleanup Task

You are given a machine with Docker installed. Your task is to fully clean the Docker environment using Docker CLI commands so that all of the following are removed:

• All containers ( including running containers )
• All images
• All volumes

Acceptance criteria

After your cleanup, the following commands should show no resources:

• docker ps -a
• docker images -a
• docker volume ls

Notes

• You may assume you have sufficient permissions to manage Docker resources.
• The goal is correctness and completeness; prefer commands that work even when containers are running or resources have dependencies.
