Docker

Use this skill when working on Docker tasks.

Workflow

• Inspect base image, build context, multi-stage use, dependency cache, user, exposed ports, volumes, and health checks.
• Avoid baking secrets into images, layers, args, logs, or Compose files.
• Validate image size, rebuild determinism, non-root runtime, signal handling, and environment-specific config.

Boundaries

• Inspect the target repository before making changes.
• Prefer existing project patterns, declared package managers, and documented validation commands.
• Do not expose secrets, credentials, private user data, or production account identifiers in source, examples, or logs.
• When external APIs or current vendor behavior matter, verify against official docs before implementation.

Provenance

• Source classification: official-docs-reference
• This is a Localsetup-native skill written from project workflow requirements and public/official documentation routing.
