Containerize applications with isolated, portable units ensuring consistency across development, testing, and production. \n \n Supports three core workflows: local development with hot-reload volumes, CI/CD image building and testing, and production deployment with health checks and resource limits \n Includes multi-stage builds to optimize image size, layer caching strategies, and .dockerignore patterns for faster builds \n Docker Compose enables multi-container applications with service depen

Orchestrate multi-container applications with declarative YAML configuration, networking, volumes, and production-ready deployments. \n \n Define entire application stacks in YAML with services, networks, volumes, and secrets; automatic service discovery enables inter-container communication by name \n Supports development, staging, and production workflows through compose file overrides and environment-specific configurations with health checks and restart policies \n Includes 16+ real-world pa

Docker and Docker Compose patterns for local development, multi-service orchestration, and container security. \n \n Covers multi-stage Dockerfiles with dev, build, and production targets; Docker Compose configuration for web app stacks with PostgreSQL, Redis, and Mailpit; and override files for environment-specific settings \n Includes service discovery via container networking, custom network isolation, and volume strategies (named volumes, bind mounts, anonymous volumes) for data persistence
