MongoDB with single replica (docker compose)

Hey everyone,

I'm Kevin, and I could use some help with Unraid and my Docker Compose file. Everything works smoothly when I'm using Docker Desktop locally, but as soon as I try it on Unraid, I can't connect to MongoDB.

Here's my Docker Compose file:

version: '3'
volumes:
  mongo1_data:
  mongo1_config:
services:
  mongo1:
    image: mongo:7.0.4
    command: ['--replSet', 'rs0', '--bind_ip_all', '--port', '27017']
    ports:
      - 27017:27017
    healthcheck:
      test: echo "try { rs.status() } catch (err) { rs.initiate({_id:'rs0',members:[{_id:0,host:'mongo1:27017'}]}) }" | mongosh --port 27017 --quiet
      interval: 5s
      timeout: 30s
      start_period: 0s
      start_interval: 1s
      retries: 30
    volumes:
      - 'mongo1_data:/data/db'
      - 'mongo1_config:/data/configdb'
  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_URL: mongodb://mongo1:27017/

I've tried a bunch of things like hardcoding the local IP to the port, changing ports, and defining networks, but none of them seem to solve the issue. What's really odd is that when I attempt to access port 27017 through a web browser, I get a message saying: "It looks like you are trying to access MongoDB over HTTP on the native driver port."

So, it appears that something is listening, but when I try to connect with MongoDB Compass or Mongo Express, it just doesn't work. This problem seems to be related to Unraid because it works perfectly fine locally.

Any ideas or suggestions would be greatly appreciated!
