Docker Compose

O que é o Docker Compose?

Docker Compose is a mature, industry-standard tool for orchestrating multi-container applications. Originally a separate Python project, it was rewritten in Go and later integrated directly into the Docker CLI as a plugin. It reads a docker-compose.yml file to define services, networks, and volumes, allowing you to bring up complex stacks with a single command. It has been stable and widely adopted for over a decade.

Ideal para: Developers and sysadmins who need to define and run multi-container applications locally or in simple production environments.

Your docker-compose.yml files from Docker Desktop work exactly the same on Linux. The main difference is that you do not have a GUI to click 'Start' or 'Stop'. Instead, use docker compose up -d to start in the background and docker compose down to stop and remove containers. If you were using the Docker Desktop dashboard to view logs, use docker compose logs -f in your terminal. Ensure your user is in the docker group to avoid using sudo for every command.
