SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams plan and implement Docker and containerization work so applications are packaged, optimized, and deployed reliably. It reduces guesswork around base image choices, build strategy, security posture, and orchestration by guiding discovery, tradeoffs, and an implementation path.

Core Features & Use Cases

  • Discovery-first workflow: Enforces an "explore" phase to restate needs, ask clarifying questions, and map existing repository container footprint before making changes.
  • Container strategy & optimization: Recommends base images, multi-stage Dockerfiles, image size tradeoffs, and caching strategies to reduce build time and runtime footprint.
  • Deployment & security guidance: Advises on orchestration choices (Compose vs Kubernetes), registry and deployment strategy, non-root runtime, environment and secret handling, and TTFT monitoring/observability considerations.
  • Use Case: For a web service monorepo, this Skill can map current startup scripts, propose a multi-stage build that trims image size, create a Compose file for local dev, and outline a production deployment and registry workflow.

Quick Start

Use the docker skill to explore containerization for this codebase, confirm the intended services to containerize, and produce a recommended multi-stage Dockerfile plus a deployment strategy.

Frequently Asked Questions about docker

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a multi-stage Dockerfile to optimize image size?▼

Multi-stage Dockerfiles optimize image size by using separate build and runtime stages to trim unnecessary dependencies. This Skill recommends base images and caching strategies to reduce both build time and runtime footprint for containerized applications.

What's the best way to containerize a web service monorepo for local development?▼

Containerizing a web service monorepo involves mapping existing startup scripts and creating a Compose file for local development. This Skill maps your current repository footprint and proposes a multi-stage build alongside a deployment strategy.

When should I use Docker Compose vs Kubernetes for production orchestration?▼

Docker Compose vs Kubernetes orchestration depends on your deployment scale and complexity requirements. This Skill advises on orchestration choices by comparing Compose for local development against Kubernetes for production deployment workflows.

How do I enforce non-root security practices in a Docker container?▼

Non-root security practices in Docker containers enforce safer runtime permissions by avoiding privileged user execution. This Skill guides you through selecting secure base images, handling environment secrets, and defining runtime ports and volumes safely.

How do I choose the right base image for a Docker containerization strategy?▼

Choosing a base image for a Docker containerization strategy requires balancing image size, security posture, and runtime dependencies. This Skill evaluates tradeoffs and recommends appropriate base images to ensure reliable application packaging.

What registry and deployment strategy should I use for Docker images?▼

Registry and deployment strategies for Docker images depend on your production environment and observability needs. This Skill outlines a production deployment workflow, including registry choices and TTFT monitoring considerations.
