Connecting outside of localhost

[dmikalova]

I'm trying to set this up on DigitalOcean on Ubuntu 20.04 and I can't seem to get the screeps port to connect to the internet. If I try another container the port is exposed fine with netcat. But with the screeps port I can't ever connect to it outside of localhost. Am I missing something?

docker-compose.yml - I would expect this to publish the screeps port to 8080, I haven't found any variation on this that works.

version: '3.2'
services:
  screeps:
    image: screepers/screeps-launcher
    volumes:
      - ./config.yml:/screeps/config.yml
      - screeps-data:/screeps
    ports:
      # - 21025:21025/tcp
      - target: 21025
        published: 8080
        protocol: tcp
        mode: host
    environment:
      MONGO_HOST: mongo
      REDIS_HOST: redis
      STEAM_KEY: $STEAM_KEY
    restart: unless-stopped

  mongo:
    image: mongo
    ports:
      - 27017:27017/tcp
    volumes:
      - mongo-data:/data/db
    restart: unless-stopped

  redis:
    image: redis
    ports:
      - 6379:6379/tcp
    volumes:
      - redis-data:/data
    restart: unless-stopped

volumes:
  redis-data:
  mongo-data:
  screeps-data:

commands:

docker-compose up -d
# netstat shows the port open
netstat -plant | grep 80
# nc can connect to the port from the machine but not from home. This works with a simple server.
nc -zvv 0.0.0.0 8080
# simple server example to validate no firewall issues
docker run --rm -p 8080:80 yeasy/simple-web:latest

Usually just having - 21025:21025 in the ports section is enough (or in your case, - 8080:21025) Also, you want to avoid having the ports exposed on the redis and mongo containers unless you have firewall setup to restrict them.

Thanks, that's what I would expect too so I'm still not sure why its not working. I'm just going to close this and keep trying other things.

@dmikalova What is the solution?

[dmikalova]

@geocine it's been a while since I set this up, but this is the config I have that's been working solid:

version: "3"
services:
  mongodb:
    image: mongo
    volumes:
      - ./mongo:/data/db
  redis:
    image: redis
  screeps:
    build: screeps
    volumes:
      - ./mods.json:/screeps/mods.json
    depends_on:
      - mongodb
      - redis
    environment:
      STEAM_API_KEY: $STEAM_API_KEY
    ports:
      - "21025:21025"

I start it like this:

export STEAM_API_KEY="x"
docker-compose up -d

and here's mods.json:

{
  "mods": [
    "node_modules/screepsmod-mongo/index.js",
    "node_modules/screepsmod-auth/index.js",
    "node_modules/screepsmod-tickrate/index.js",
    "node_modules/screepsmod-admin-utils/index.js",
    "node_modules/screepsmod-features/index.js"
  ],
  "bots": {
    "simplebot": "node_modules/@screeps/simplebot/src"
  }
}
