Docker Compose overview

Short summary

Docker Compose runs multi-container applications from a single YAML file, eliminating the need to install each service on your host machine. Master core concepts (services, networks, volumes), essential commands, and practical patterns for development stacks combining API servers, databases, and message brokers. Includes ready-made examples and a complete command reference.

• •Define multi-container stacks in YAML; services resolve each other by name on Compose's default network
• •Master essential commands: docker compose up, down, logs, exec, and ps for local development workflows
• •Use named volumes for persistent data, bind mounts for live code reload, and depends_on/healthchecks for container readiness
