Managing Containers with Docker Compose

Microservices often rely on several components. Think of a Spring Boot application needing a database, a message queue, or another API service.

Each component typically runs in its own Docker container. Managing these individually can become complex, especially during development.

How do we start them all together, ensure they can communicate, and manage their lifecycle efficiently? This is where Docker Compose steps in!

Docker Compose is a tool for defining and running multi-container Docker applications. Instead of managing each container separately, you define all services in a single, easy-to-read file.

This definition file is typically named docker-compose.yml. It uses YAML syntax, which is both human-readable and machine-parseable.

Compose simplifies your development workflow by letting you spin up your entire application stack with a single command.
