Multiple Instances of Transmission — same container or different containers?

[wally-crunk]

I'm able to run three (3) concurrent docker containers on the same machine using PIA, and it works great.

However, each one has its own docker-compose.yml file.

To make life easier, I thought I would consolidate my three (3) docker-compose.yml files into one file, but the resulting "docker compose up" doesn't work. One of the containers will start up correctly, but then the next containers will fail:

foo exited with code 0
bar exited with code 0

The docker-compose.yml was set up this way, basically concatenating everything under the 'services' section, assigning each session its own service name.

version: '3.3'
services:
    foo:
        container_name: "foo01"
        cap_add:
            - NET_ADMIN
        volumes:
            - etc
        environment:
            - etc
        logging:
            driver: json-file
            options:
                max-size: 10m
        ports:
            - '9001:9091'
        image: haugene/transmission-openvpn
    bar:
        container_name: "bar01"
        cap_add:
            - NET_ADMIN
        volumes:
            - etc
        environment:
            - etc
        logging:
            driver: json-file
            options:
                max-size: 10m
        ports:
            - '9003:9091'
        image: haugene/transmission-openvpn
    blatz:
        container_name: "blatz01"
        cap_add:
            - NET_ADMIN
        volumes:
            - etc
        environment:
            - etc
        logging:
            driver: json-file
            options:
                max-size: 10m
        ports:
            - '9005:9091'

Confused why this wouldn't work! Any clues?
