| Docker compose predictable bridge | 2018-09-25 | How to use a predefined bridge with docker compose |
|
The problem
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.
The fix
For example if your bridge is named docbr1, 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: docbr1 {{< /highlight >}}
