Question

我正在开发一个已经停靠的express.js应用程序。这是我给书架的配置信息。

{
    "database_dev" : {
        "client": "mysql",
        "connection": {
            "host": "DB",
            "database": "TERRA_DEV",
            "user": "dev",
            "port": "3306",
            "password": "goon",
            "charset": "utf8",
            "host": ""
        }
    },

    "database_test" : {
        "client": "mysql",
        "connection": {
            "host": "DB",
            "database": "TERRA_TEST",
            "user": "tester",
            "port": "3306",
            "password": "goon",
            "charset": "utf8",
            "host": ""
        }
    },
....

这是我的docker-compose.test.yml我正在运行以尝试执行我的测试。

version: '2'
volumes:
services:
 sut:
     build: .
     command: npm test
     depends_on:
         - web
 web:
    build: .
    command: "npm start"
    volumes:
      - .:/usr/app/
      - /usr/app/node_modules
    ports:
      - "3000:3000"
    depends_on:
      - redis
      - DB
    networks:
        - web_sql_bridge

 redis:
    image: 'bitnami/redis:latest'
    environment:
        - ALLOW_EMPTY_PASSWORD=yes
    ports:
        - '6379:6379'
 DB:
     image: mysql:5.7
     restart: always
     environment:
         - MYSQL_ROOT_PASSWORD="goon"
         - MYSQL_DATABASE="TERRA_TEST"
         - MYSQL_DATABASE="TERRA_DEV"
         - MYSQL_USER="tester"
         - MYSQL_PASSWORD="goon"
     ports:
         - "3306:3306"
     networks:
         - web_sql_bridge
volumes:
    appconf:

networks:
  web_sql_bridge:
    driver: bridge

这是错误

Error: connect ECONNREFUSED 127.0.0.1:3306
sut_1    |     at Object._errnoException (util.js:1022:11)
sut_1    |     at _exceptionWithHostPort (util.js:1044:20)
sut_1    |     at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1198:14)
sut_1    |     --------------------
sut_1    |     at Protocol._enqueue (/TerraServer/node_modules/mysql/lib/protocol/Protocol.js:145:48)
sut_1    |     at Protocol.handshake (/TerraServer/node_modules/mysql/lib/protocol/Protocol.js:52:23)
sut_1    |     at Connection.connect (/TerraServer/node_modules/mysql/lib/Connection.js:130:18)

所以基本上你可以从上面看到我有一个config.json，其中包含一些JS文件中的数据库信息，并将其作为参数提供给bookshelf.js。这在我的mocha测试中用于抛出我发布的错误。该错误似乎表明它试图连接到127.0.0.1。当我给它DB时，为什么bookshelf.js尝试连接到127.0.0.1？

我发现了我的问题。结果我需要跑。

docker system prune -a

当我第二次构建时，它不会更新文件，我的配置文件在图像中落后，而不是我的repo，它会拉动代码。

并删除了DB环境中的引号。

DB:
     image: mysql:5.7
     restart: always
     environment:
         - MYSQL_ROOT_PASSWORD=goon
         - MYSQL_DATABASE=TERRA_TEST
         - MYSQL_DATABASE=TERRA_DEV
         - MYSQL_USER=tester
         - MYSQL_PASSWORD=goon

Bookshelf.js没有连接到正确的主机？
