Docker Swarm (arm) Gateway Cannot Start

I’m trying to run the ignition docker image on a docker swarm (arm/v7 processors).

networks:
   ignet:
     external:
       name: ignet
services:
  distributor:
    environment:
      GATEWAY_ADMIN_PASSWORD: password
      IGNITION_EDITION: full
    image: ignition_configured
    networks:
      ignet:
        ipv4_address: 172.25.1.2

The image is just the base kcollins/ignition image with the MQTT Distributor module installed and committed.

The network was created like this:

docker network create -d overlay ignet --subnet 172.25.0.0/16

The setup works in non-swarm mode (docker-compose up) and works on my amd system in both swarm and non-swarm modes. On the arm swarm, though, I get the following error:

Where the line wrapper | 2021/04/07 16:06:03 | INT trapped. Shutting down. seems to be the first place of divergence from normal behavior.

Any help would be greatly appreciated!
