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

但始终，当我尝试使用以下命令部署应用程序时： gcloud app deploy --stop-previous-version过程结束，出现此错误：

第 0 步：应用程序检测失败：错误：node.js 检查器：“package.json”的“scripts”部分中的“start”和“server.js”文件均未找到。

server/package.json是：

{
  "name": "server",
  "version": "1.5.2",
  "engines": {
    "node": "13.x"
  },
  "main": "server.js",
  "description": "ConstaFAST server",

    "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"
  },

    "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

我看不到指定package.json和server.js文件的位置的方法，无论是在app.yaml 参考中，还是在gcloud app deploy 参考中，所以我猜它必须并排放置使用app.yaml文件（如示例应用程序中所示）。

您看到的错误很可能是由于部署命令没有在它期望的位置找到提到的文件造成的。

换句话说，您必须移动/复制server目录中的app.yaml文件。 这可能是可能的符号链接文件，以避免实际的重复代码，如果你想也从另一个目录进行部署（它为标准的环境，但我不能肯定这同样适用于灵活的一个真实）。

旁注：我认为您的静态处理程序（我怀疑这也可能是您寻求此类应用程序结构的原因）不会起作用 - app.yaml 参考或Serving Static Files 中没有提及此类功能部分。 也许您不小心查看了标准环境文档？ （检查如何判断 Google App Engine 文档页面是否适用于第 1/2 代标准或灵活环境）如果您删除处理程序，那么app.yaml文件中所剩的很少 - 一个相当低的重用价值努力做到这一点（如果可能的话）。 我只是保持简单并坚持推荐的方式。
