#### Set bridge name in docker-compose.yml

I’m running a dockerized GitLab instance with "userns-remap" enabled and I’d like to use a shared PostgreSQL on the host. The bridge created when I docker-compose up, however, gets a new random name "br-xxxxxxxxxxxx" on every run.

This wouldn’t usually be a problem, but the Vuurmuur firewall on the host blocks all traffic from the container to the host by default and I need the bridge name in order to set an allowing rule on Vuurmuur.

I found a number of related topics e.g. com.docker.network.bridge.name, but I’m having trouble puzzling it all together. So far, I’ve tried to find a way to make sure every time the container is upped, the bridge gets the same name and same IP/mask assigned. Is this even possible in docker-compose.yml or is this approach utterly wrong?

Here’s the unspectactular docker-compose.yml so far:

version: '3.8'
services:
web:
image: 'gitlab/gitlab-ce:latest'
restart: always
hostname: 'gitlab.example.com'
environment:
GITLAB_OMNIBUS_CONFIG: |
external_url 'https://gitlab.example.com'
