+  How to use a predefined bridge with docker compose
+---
+
+By default, docker-compose will create a network with a randomly named bridge. If you are like me using a strict firewall on all your machines, this just cannot work.
+
+You need to put your services in `network_mode: “bridge”` and add a custom `network` entry like :
+
+{{< highlight yaml >}}
+version: '3.0'
+
+services:
+  sshportal:
+    image: moul/sshportal
+    environment:
+      - SSHPORTAL_DEFAULT_ADMIN_INVITE_TOKEN=integration
+    command: server --debug
+    depends_on:
+      - testserver
+    ports:
+      - 2222
+    network_mode: "bridge"
+networks:
+  default:
+    external:
+      name: bridge
