Docker Compose

If you’re app is deployed using docker compose you can add Metlo as a service to capture API traffic data as shown below:

version: "3.9"

services:
  <your-service>:
    ...
  metlo:
    image: metlo/agent
    network_mode: "service:<your-service>"
    depends_on:
      - <your-service>
    cap_add:
      - NET_ADMIN
    environment:
      - METLO_HOST=http://<YOUR_METLO_HOST>:8081
      - METLO_KEY=<YOUR_METLO_API_KEY>

Be sure to set the network_mode to "service:<your-service>" so Metlo can reuse your service’s network stack and listen to API traffic.

By default Metlo automatically detects the interface to listen to but you can specify the INTERFACE environment variable if you want to change it.
