What problem does it solve?
Docker and Docker Compose configurations are often inconsistent, insecure, or poorly optimized for development and production parity; this Skill provides clear patterns to standardize local stacks, container security, networking, and volume strategies to reduce runtime failures and operational surprises.
Core Features & Use Cases
- Composable Development Stacks: Opinionated docker-compose layouts for multi-service applications with development overrides and production overlays.
- Multi-stage Dockerfiles: Patterns for dev, build, and production stages to minimize image size and enable hot-reload during development.
- Networking & Volume Strategies: Service discovery by name, custom network segmentation, named volumes for persistence, and bind mounts for hot reload.
- Security & Hardening: Non-root users, pinned image tags, read-only filesystems, capability drops, healthchecks, and secret management recommendations.
- Debugging & Maintenance: Common commands for logs, exec, inspect, rebuilds, and destructive cleanup with safety notes.
- Use Case Example: Scaffold a Node.js web app with Postgres and Redis for local development, include init scripts, healthchecks, and a mail testing service.
Quick Start
Generate a docker-compose.yml and a multi-stage Dockerfile for a Node.js web app with Postgres and Redis that includes named volumes, healthchecks, non-root user configuration, and a development override for hot-reload.
