Докер-контейнер mongodb с Нодейс

/ 29 декабря 2018

Я пытаюсь докернизировать мой API, но когда я запускаю приложение с файлом docker-compose, mongodb не запускается, и приложение не может подключиться к базе данных.При запуске тестов приложения с использованием docker тесты выполняются правильно, но при запуске npm запускается производство, служба mongodb запускается и деактивируется.

docker-compose.yml 

version: '3'
services:
  backend:
    build: 
      context: ../
      dockerfile: docker/Dockerfile.production 
      args:
        port: ${PORT}
    env_file:
      - ../.env
    restart: always
    ports:
      - "${PORT}:${PORT}"
    environment:
      WAIT_HOSTS: database:27017
  database:
    image: mongo:latest
    env_file:
      - ../.env
    volumes:
      - ".${MONGO_DATA_DIR}:${MONGO_DATA_DIR}"
    expose:
      - 27017
    command: "mongod --smallfiles --logpath=${MONGO_LOG_FILE}"

docker-compose.test.yml 

version: '3'
services:
  backend-test:
    build: 
      context: ../
      dockerfile: docker/Dockerfile.test
      args:
        port: ${PORT}
    env_file:
      - ../.env
    environment:
      WAIT_HOSTS: database-test:27017
  database-test:
    image: mongo:latest
    env_file:
      - ../.env
    volumes:
      - ".${MONGO_TEST_DATA_DIR}:${MONGO_TEST_DATA_DIR}"
    expose:
      - 27017
    command: "mongod --smallfiles --logpath=${MONGO_LOG_FILE}"

Запуск npm run test, приложение работает и выполняет модульные тесты, но когда япопробуйте запустить npm run production, служба mongodb не запускается, поэтому приложение не работает.

Проблема должна заключаться в том, что при запуске сервера БД еще не создана.Вам нужен скрипт, чтобы сервер запускался только после создания базы данных.

Для получения дополнительной информации у вас есть эта ссылка https://docs.docker.com/compose/startup-order/

Или репозиторий, созданный мной с этой проблемой https://github.com/PedroS11/node-postgres-redis-docker
