How to run two instances on different ports

[farlo18]

I currently have one docker instance running (which by the way works fantastic, thank you) on port 30000. I have a second license for Foundry and am trying to have another container running on port 30001. Is this something that can work? Below is what spits out in the container logs as you can see it says port 30000 even though the options.json has 30001 listed. I checked the container details and thats below showing its picking up 30000. Thank you for any help or guidance.

Great question!
I've answered it before in other places, but I guess not in this repository's discussions.

Here is an example docker-compose.yml file that should do what you're trying to accomplish:

---
version: "3"

secrets:
  credentials:
    file: credentials.json

services:
  foundry_1:
    image: felddy/foundryvtt:release
    hostname: my_foundry_host_1
    init: true
    volumes:
      - type: bind
        source: ./data_1
        target: /data
    environment:
      - CONTAINER_CACHE=/data/container_cache
      - FOUNDRY_LICENSE_KEY=1
    secrets:
      - source: credentials
        target: config.json
    ports:
      - target: 30000
        published: 30000
        protocol: tcp
  foundry_2:
    image: felddy/foundryvtt:release
    hostname: my_foundry_host_2
    init: true
    volumes:
      - type: bind
        source: ./data_2
        target: /data
    environment:
      - CONTAINER_CACHE=/data/container_cache
      - FOUNDRY_LICENSE_KEY=2
    secrets:
      - source: credentials
        target: config.json
    ports:
      - target: 30000
        published: 30001
        protocol: tcp

I can't believe it was as simple as changing only the published port (I was changing both). It works perfectly. Thank you again!
