What problem it solves

Multi-container applications require coordinated configuration for their services, environments, and dependencies. Docker Compose provides a Compose file format and a command-based workflow to define, create, and start those services together.

Key features

• Define application services — A Compose file describes how the containers that make up an application are configured. Services can be built from a Dockerfile or use container images.

  Source: README

• Start applications together — Compose starts and runs the defined services with one command, allowing the application to be launched as a coordinated unit.

  Source: README

• Configure reproducible environments — Applications can be defined with a Dockerfile and Compose services in an isolated environment. The example shows build configuration, ports, volumes, and an image-based service.

• Use the Compose file format — Compose uses the Compose file format to represent application services and their configuration.

Quick start

Copied verbatim from the project's README.

services:
  web:
    build: .
    ports:
      - "5000:5000"
    volumes:
      - .:/code
  redis:
    image: redis

Who it may suit

This project may suit developers and teams that define applications composed of multiple containers and want to run those services together through a configuration file.

Topics to discuss

• Which Compose file patterns are most useful for common application architectures?

• How can Compose workflows better support development, testing, and deployment environments?

• What improvements to the Compose file format or command-line workflow would help users manage multi-container applications?
