Connection refuse during Migration inside the Docker - Laravel 5.8

I can not seem to be able to make a migration while during my docker build

I've tried

docker-compose.yml

version: '3'
services:
  portalmodules:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - 8011:8000
    links:
      - database
  database:
    image: postgres:11.2
    ports:
    - "5432:5432"
    expose:
    - "5432"
    environment:
      - "POSTGRES_PASSWORD=12345"
      - "POSTGRES_USER=john"
      - "POSTGRES_DB=api"
