Docker Management

Purpose

• Use this skill to run, inspect, debug, and clean up Docker workloads.
• Prefer it when the task involves containers, images, networks, volumes, or Compose stacks.
• This skill covers both day-to-day lifecycle operations and practical debugging patterns.

Core Mental Model

• Images are immutable build artifacts.
• Containers are running or stopped instances of images.
• Volumes persist data outside the container filesystem lifecycle.
• Networks define service-to-service connectivity.
• Compose describes multi-container applications declaratively.
