Question

我尝试使用wercker，但我不知道我的测试无法连接到我的mongodb。

我使用sails + sails mongo，当npm测试...我总是得到错误可以连接到mongo db，这是我的wercker.yml：

box: nodesource/trusty:0.12.7
services:
  - id: mongo:2.6
# Build definition
build:
  # The steps that will be executed on build
  steps:
    - script:
        name: set NODE_ENV
        code: export NODE_ENV=development
    # A step that executes `npm install` command
    - npm-install
    # A step that executes `npm test` command
    - npm-test
    # A custom script step, name value is used in the UI
    # and the code value contains the command that get executed
    - script:
        name: echo nodejs information
        code: |
          echo "node version $(node -v) running"
          echo "npm version $(npm -v) running"

这是我的错误消息：

warn: `sails.config.express` is deprecated; use `sails.config.http` instead.

  1)  "before all" hook:
     Uncaught Error: Failed to connect to MongoDB.  Are you sure your configured Mongo instance is running?
 Error details:
{ [MongoError: connect ECONNREFUSED] name: 'MongoError', message: 'connect ECONNREFUSED' }

  2)  "after all" hook:
     Uncaught Error: Failed to connect to MongoDB.  Are you sure your configured Mongo instance is running?
 Error details:

开箱即用时，MongoDB没有身份验证，因此您只需提供正确的主机和端口。

在config/connection.js中的sails应用中定义新连接：

    mongodbTestingServer: {
        adapter: 'sails-mongo',
        host:    process.env.MONGO_PORT_27017_TCP_ADDR,
        port:    process.env.MONGO_PORT_27017_TCP_PORT
    },

关于MONGO_PORT_27017_TCP_ADDR和MONGO_PORT_27017_TCP_PORT，这两个环境变量是由Wercker在您声明mongo服务时创建的。 就像那样，您将能够使用正确的主机和端口将您的应用程序连接到您的数据库。

在config/env/testing.js的风帆应用中添加新环境。它将由Wercker使用：

module.exports = {
    models: {
        connection: 'mongodbTestingServer'
    }
};

在您的wercker文件wercker.yml中。我建议您使用 ewok堆栈（基于Docker），您可以在应用程序的设置中激活它。以下是有关migration to Ewok stack的一些有用信息。我的示例使用基于Docker镜像的框。

# use the latest official stable node image hosted on DockerHub 
box: node
# use the mongo (v2.6) image hosted on DockerHub 
services:
  - id: mongo:2.6
# Build definition
build:
    steps:
    # Print node and npm version
    - script:
        name: echo nodejs information
        code: |
            echo "node version $(node -v) running"
            echo "npm version $(npm -v) running"
    - script:
        name: set NODE_ENV
        code: |
            export NODE_ENV=testing
    # install npm dependencies of your project
    - npm-install
    # run tests
    - npm-test

要查看Wercker构建中的所有环境变量，请添加以下行：

- script:
    name: show all environment variables
    code: |
        env

它应该有用。
