Google App Engine-使用相同的app.yaml部署不同的文件夹

Question

我有这个文件夹树：

这是我实际的app.yaml：

runtime: nodejs
env: flex

manual_scaling:
  instances: 1
resources:
  cpu: 1
  memory_gb: 0.5
  disk_size_gb: 10

handlers:
  - url: /api/.*
    static_files: server/server.js
    upload: server/server.js
  - url: /
    static_files: www/build/index.html
    upload: www/build/index.html
  - url: /
    static_dir: www/build

但是总是，当我尝试使用以下命令部署应用程序：gcloud app deploy --stop-previous-version时，进程结束并显示此错误：

步骤＃0：应用程序检测失败：错误：node.js检查器：找不到“ package.json”的“脚本”部分中的“开始”，也找不到“ server.js”文件。

server/package.json是：

{
  "name": "server",
  "version": "1.5.2",
  "engines": {
    "node": "13.x"
  },
  "main": "server.js",
  "description": "ConstaFAST server",
  "scripts": {
    "start": "node server.js"
  },
  "license": "MIT",
  "dependencies": {
    "@hapi/joi": "^16.1.7",
    "base64-img": "^1.0.4",
    "bcryptjs": "^2.4.3",
    "body-parser": "^1.19.0",
    "dotenv": "^8.2.0",
    "express": "^4.17.1",
    "generate-password": "^1.4.2",
    "jsonwebtoken": "^8.5.1",
    "mongoose": "^5.8.4",
    "nodemailer": "^6.4.2",
    "pdfkit": "^0.11.0",
    "qrcode": "^1.4.4"
  },
  "devDependencies": {
    "morgan": "^1.9.1"
  }
}

而www/package.json是：

{
  "name": "www",
  "version": "0.1.6",
  "private": true,
  "engines": {
    "node": "13.x"
  },
  "dependencies": {
    "@material-ui/core": "^4.8.2",
    "@material-ui/icons": "^4.5.1",
    "bootstrap": "^4.4.1",
    "formik": "^2.1.1",
    "jspdf": "^1.5.3",
    "qrcode": "^1.4.4",
    "qrcode.react": "^1.0.0",
    "react": "^16.11.0",
    "react-bootstrap": "^1.0.0-beta.14",
    "react-dom": "^16.11.0",
    "react-router": "^5.1.2",
    "react-router-dom": "^5.1.2",
    "react-scripts": "3.3.0",
    "react-stripe-elements": "^6.0.1",
    "yup": "^0.28.0"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

最后，server/server.js的内容是：

const express = require('express');
const app = express();
const path = require('path');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
require('dotenv').config()

const agencyRoutes = require('./api/routes/agency');
const companyRoutes = require('./api/routes/company');
const userRoutes = require('./api/routes/user');
const qrcodeRoutes = require('./api/routes/qrcode');
const vehicleRoutes = require('./api/routes/vehicle');
const writerRoutes = require('./api/routes/writer');

const port = process.env.PORT || 8080;

mongoose.connect(String(process.env.DB_CONNECT), {
  useCreateIndex: true,
  useNewUrlParser: true,
  useUnifiedTopology: true
}, () => console.log('Connect to the database'));

mongoose.Promise = global.Promise;

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

app.use( (req, res, next) => {
  res.header('Access-Control-Allow-Origin', 'https://constafast.cf');
  res.header(
    'Access-Control-Allow-Headers',
    'Origin, X-Requested-With, Content-Type, Accept, Authorization'
    );
  res.header('Connection', 'Keep-Alive');

  if ( req.method === 'OPTIONS' ) {
    res.header('Access-Control-Allow-Methods', 'PUT, POST, PATCH, DELETE, GET');
    return res.status(200).json({});
  }

  next();
});

app.use(express.static(path.resolve(__dirname, '../www', 'build')));

app.use('/api/agency', agencyRoutes);
app.use('/api/company', companyRoutes);
app.use('/api/user', userRoutes);
app.use('/api/qrcode', qrcodeRoutes);
app.use('/api/vehicle', vehicleRoutes);
app.use('/api/writer', writerRoutes);

app.get('*', (req, res) => {
  res.sendFile(path.resolve(__dirname, '../www', 'build', 'index.html'));
});

app.use( (req, res, next) => {
  const error = new Error('Not found');
  error.status = 404;
  next(error);
});

app.use( (error, req, res, next) => {
  res.status(error.status || 500);
  res.json({
    error: {
      message: error.message
    }
  });
});

app.listen(port, () => console.log(`Server up and running on port ${port}`));
module.exports = app;

Answer 1

我无法在app.yaml reference和gcloud app deploy reference中都无法指定package.json和server.js文件的位置，所以我猜想是必须与app.yaml文件并排放置（如sample app所示）。

您看到的错误很可能是由于部署命令没有在期望的位置找到提到的文件引起的。

换句话说，您必须移动/复制app.yaml目录中的server文件。如果您还想从另一个目录进行部署，可能 符号链接该文件以避免实际的代码重复（它适用于标准环境，但是我不确定对于灵活的环境也是如此）一个）。

侧面说明：我认为您的静态处理程序（我怀疑这可能也是您寻求此类应用程序结构的原因）不会起作用-在app.yaml reference或Serving Static Files部分。也许您不小心查看了标准环境文档？ （请检查How to tell if a Google App Engine documentation page applies to the 1st/2nd generation standard or the flexible environment）如果您删除处理程序，则app.yaml文件中几乎没有剩余-这样做的重用值相当低（即使可能）。我只是保持简单，并遵循推荐的方式。
