無法將 NodeJS + AngularJS 應用程序推送到 PAS - Pivotal Cloud Foundry (PCF)

Question

我正在嘗試推送 nodejs/angularjs 應用程序，但出現以下錯誤。

> Instance never healthy after 1m0s: Failed to make TCP connection to
> port 8080: connection refused; process did not exit

我嘗試了以下但失敗了（抱歉，我是新手）：

1. 使用 -t 將運行狀況檢查的超時時間增加到 600 或更多，但仍然失敗。
2. 擴大了資源（RAM等），但這也無濟於事。
3. 等了一夜，問題就神奇地消失了……

這是我們的 package.json 的樣子：

{
  "name": "apptheone",
  "private": true,
  "version": "1.0.0",
  "description": "bla bla blaa",
  "license": "MIT",
  "devDependencies": {

    "check-dependencies": "^1.1.0",
    "eslint": "^4.19.1",
    "eslint-config-google": "^0.9.1",
    "http-server": "^0.10.0",
    "loadash": "^1.0.0",
    "mocha": "^5.0.5",
    "protractor-jasmine2-html-reporter": "0.0.7"
  },
  "scripts": {
    "update-deps": "npm update",
    "start": "node build.js && http-server -a localhost -p 8000 -c-1 ./app",
    "protractor": " cd ./tests && protractor protractor.conf.js",
    "test": "node node_modules/mocha/bin/mocha node-red/test/**/*.js"
  },
  "dependencies": {
    "auditjs": "^2.4.3",
    "bower": "^1.8.4",
    "dependency-check": "^3.1.0",
    "jslint": "^0.11.0",
    "json-formatter-js": "^2.2.0",
    "npm": "^5.8.0",
    "requirejs": "^2.3.5",
    "shelljs": "^0.8.3"
  }
}

注意：當我第一次嘗試推送應用程序時，我能夠使用簡單的cf push apptheone成功地做到這一點，並且 static 網頁也已上線。 但后來我在玩 PCF UI 並刪除了應用程序及其關聯的服務/路由，從那以后我就無法推送同一個應用程序。 完全沒有對應用程序代碼進行任何更改。

請仔細檢查您的應用程序是否正在監聽0.0.0.0而不是localhost 。 僅在localhost上偵聽時，這可能會導致運行狀況檢查失敗，因為您的應用在運行它的容器之外不可用。

希望有幫助！
