无法将 NodeJS + AngularJS 应用程序推送到 PAS - Pivotal Cloud Foundry (PCF)

Question

我正在尝试推送 nodejs/angularjs 应用程序，但出现以下错误。

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

我试过以下但惨败（抱歉，我是新手）：

使用 -t 将运行状况检查的超时时间增加到 600 或更多，但它仍然失败。
升级资源（RAM 等），但这也没有帮助。
等了一整夜，问题神奇地消失了...

这是我们的 package.json 的样子：

{
  "name": "apptheone",
  "private": true,
  "version": "1.0.0",
  "description": "bla bla blaa",
  "license": "MIT",
  "devDependencies": {
    "chai": "^4.1.2",
    "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： 当我第一次尝试推送应用程序时，我能够通过一个简单的 cf push apptheone 成功地做到这一点并且静态网页是实时的出色地。但后来我在玩 PCF UI 并删除了应用程序及其关联的 services/routes，从那以后我就无法推送同一个应用程序。应用程序代码完全没有变化。

请仔细检查您的应用程序正在侦听 0.0.0.0 而不是 localhost。仅在 localhost 上侦听时，这可能会导致运行状况检查失败，因为您的应用在运行.

所在的容器之外不可用

希望对您有所帮助！
