Docker Compose example

    • Edit a file with the following content:

    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 as described in the example below. You can use a pre-existing network too.

    1. version: "3.3"
    3. networks:
    4.   traefiknet: {}
    6. services:
    8.   traefik:
    9.     image: "traefik:v2.10"
    11.       - traefiknet
    13.   whoami:
    14.     image: "traefik/whoami"
    15.     ...
    16.     networks:
    17.       - traefiknet
    • Replace whoami.localhost by your own domain within the traefik.http.routers.whoami.rule label of the whoami service.
    • Run within the folder where you created the previous file.

    Details

    • As an example, we use whoami (a tiny Go server that prints OS information and HTTP request to output) which was used to define our simple-service container.

    1. command:
    2.   # Traefik will listen to incoming request on the port 80 (HTTP)
    3.   - "--entrypoints.web.address=:80"
    5. ports:
    6.   - "80:80"
    • We expose the Traefik API to be able to check the configuration if needed:

    If you are working on a remote server, you can use the following command to display configuration (require curl & jq):

    • We allow Traefik to gather configuration from Docker:
