Error with docker : ECONNREFUSED

[lud-wj]

I'm trying to follow the docs with this configuration:

  mongo:
    image: "mongo:latest"
    environment:
      - MONGO_INITDB_ROOT_USERNAME=root
      - MONGO_INITDB_ROOT_PASSWORD=password
    volumes:
      - mongodata:/data/db

  growthbook:
    image: "growthbook/growthbook:latest"
    ports:
      - "3000:3000"
      - "3100:3100"
    depends_on:
      - mongo
    environment:
      - MONGODB_URI=mongodb://root:password@mongo:27017/growthbook?authSource=admin
      # Proxy settings
      - PROXY_ENABLED=1
      - PROXY_HOST_INTERNAL=http://proxy:3300
      - PROXY_HOST_PUBLIC=http://localhost:3300
      # Change this to something secure in production!
      - SECRET_API_KEY=dev
    volumes:
      - uploads:/usr/local/src/app/packages/back-end/uploads

  proxy:
    image: "growthbook/proxy:latest"
    ports:
      - "3300:3300"
    depends_on:
      - growthbook
    environment:
      - GROWTHBOOK_API_HOST=http://growthbook:3100
      # This must match the SECRET_API_KEY above
      - SECRET_API_KEY=dev

volumes:
  uploads:
  mongodata:

But the proxy will just exit :

The ports seem to work well:

curl http://localhost:3100/
{
  "name": "GrowthBook API",
  "production": false,
  "api_host": "http://localhost:3100",
  "app_origin": "http://localhost:3000",
  "config_source": "db",
  "email_enabled": false,
  "build": {
    "sha": "f9349da702a37711118e1daf429f4475c6ea22ca",
    "date": "2023-10-30T22:43:19Z"
  }
}                                                                                                        

curl http://172.21.0.3:3100/
{
  "name": "GrowthBook API",
  "production": false,
  "api_host": "http://172.21.0.3:3100",
  "app_origin": "http://localhost:3000",
  "config_source": "db",
  "email_enabled": false,
  "build": {
    "sha": "f9349da702a37711118e1daf429f4475c6ea22ca",
    "date": "2023-10-30T22:43:19Z"
  }
}

So maybe a bug?

OK I added this to growthbook service:

    healthcheck:
      test: ["CMD", "wget", "http://localhost:3100"]
      interval: 1s
      timeout: 1s
      retries: 10

And changed the proxy service with this:

    depends_on:
      growthbook:
        condition: service_healthy
