wercker for sails + mongo db

Question

我嘗試使用wercker, 但我不知道我的測試無法連接到我的mongodb。

我使用帆+帆蒙戈，當NPM測試...我總是得到錯誤可以連接到蒙戈分貝，這是我的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" 

這是我的錯誤消息：

warn: `sails.config.express` is deprecated; use `sails.config.http` instead. 
Express midleware for passport 
error: A hook (`orm`) failed to load! 
    1) "before all" hook 
    2) "after all" hook 

    0 passing (2s) 
    2 failing 

    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' } 
     at net.js:459:14 

    2) "after 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' }

雖然開箱即用，但MongoDB沒有身份驗證，所以您只需提供適當的主機和端口即可。

1. 定義在config/connection.js在你的船帆應用一個新的連接：

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

關於MONGO_PORT_27017_TCP_ADDR和MONGO_PORT_27017_TCP_PORT，通過Wercker被創建時，你聲明的蒙戈服務這兩個環境變量。 就像這樣，您將能夠通過正確的主機和端口將您的應用程序連接到您的數據庫。

1. 在您的sails sails應用程序中添加新環境config/env/testing.js。它將被用於通過Wercker：

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

在你wercker文件wercker.yml。我建議您使用ewok堆棧（基於Docker），您可以在應用程序的設置中激活它。以下是有關migration to Ewok stack的一些有用信息。我的例子使用基於Docker鏡像的盒子。

# 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 

要查看您的Wercker所有環境變量建立，加入這一行：

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

它應該工作。
