# Docker-compose basic example
# Docker Compose example
In this section we quickly go over a basic docker-compose file exposing a simple service using the docker provider.
This will also be used as a starting point for the other docker-compose guides.

??? Networking
The Traefik container has to be attached to the same network as the containers to be exposed.
If no networks are specified in the docker-compose file, Docker creates a default one that allows Traefik to reach the containers defined in the same file.
You can [customize the network](https://docs.docker.com/compose/networking/#specify-custom-networks) as described in the example below.
You can use a [pre-existing network](https://docs.docker.com/compose/networking/#use-a-pre-existing-network) too.
