Docker Compose orchestrates multi-service local development environments by defining web applications, PostgreSQL, and Redis in a single YAML file. This Skill provides ready-to-use configurations for common web stacks to simplify local container management and service discovery.

Optimizing a Dockerfile for smaller production images is best achieved using multi-stage builds. This Skill demonstrates multi-stage Dockerfile patterns that compile efficiently and apply security hardening by running as non-root users and dropping capabilities.

Docker handles data persistence and networking through custom network creation and effective volume strategies. This Skill explains how to configure service discovery and manage volumes to maintain state across development workflows and complex multi-container architectures.

Managing secrets securely in Docker containers is possible by applying security best practices. This Skill details how to secure local development environments by running containers as non-root users, dropping capabilities, and implementing specific secret management strategies.

Multi-container architecture networking issues in Docker often arise from misconfigured custom networks or service discovery. This Skill addresses debugging common container issues by providing patterns for proper network creation and multi-service orchestration.
