无法将 typescript express 应用程序部署到 Azure

Question

我正在尝试将一个简单的 typescript express 应用程序部署到 Azure。我发现这篇有用的博文...

我想将 typescript 代码转换为部署的一部分。

http://Codefoster.com/tscazure

主要是安装azure cli

npm install -g azure-cli

然后创建自定义部署脚本

npm site deploymentscript --node

所以现在我在项目的根目录中有一个 .deployment 文件...

[config]
command = deploy.cmd

还在根目录下有一个 deploy.cmd，我对其进行了修改以添加以下部分...

:: 3. Install npm packages
IF EXIST "%DEPLOYMENT_TARGET%\package.json" (
  pushd "%DEPLOYMENT_TARGET%"
  call :ExecuteCmd !NPM_CMD! install --production
  IF !ERRORLEVEL! NEQ 0 goto error
  popd
)

:: 4. Compile Typescript

TSC="$DEPLOYMENT_TARGET/node_modules/typescript/bin/tsc"
echo "Building Typescript files."
"$TSC"
exitWithMessageOnError "Could not run 'tsc'.  Did 'npm install'"

根目录中还有一个 package.json 文件，其中包含此...

{
  "name": "api-server",
  "version": "1.0.0",
  "description": "API server",
  "main": "index.js",
  "scripts": {
    "build": "tsc",
    "start": "node build/src | pino-colada",
    "dev": "ts-node src | pino-colada"
 },
 "author": "",
 "license": "ISC",
 "dependencies": {
    "@babel/types": "^7.8.0",
    "@types/express": "^4.17.2",
    "azure-cli": "^0.10.20",
    "bcrypt": "^3.0.7",
    "bookshelf": "^1.0.1",
    "express": "^4.17.1",
    "express-pino-logger": "^4.0.0",
    "jsonwebtoken": "^8.5.1",
    "knex": "^0.20.7",
    "mysql": "^2.17.1",
    "pino-colada": "^1.5.0",
    "typescript": "^3.7.4",
    "validator": "^12.1.0"
 },
 "proxy": "http://localhost:3201"
}

我将代码推送到 GitHub 并使用默认设置创建 WebApp（Linux 和 Node LTS）

我从 Azure 部署，部署失败，日志显示这个...

Command: deploy.cmd
/opt/Kudu/Scripts/starter.sh: line 2: exec: deploy.cmd: not found
/opt/Kudu/Scripts/starter.sh: line 2: exec: deploy.cmd: not found\n/opt/Kudu/Scripts/starter.sh deploy.cmd

那我做错了什么？

Answer 1

对...

在经历了很多心痛之后，我终于做到了。根本问题是我的开发盒是 Windows，而 Azure Web App 是 Linux。因此 deploy.cmd 根本不会飞。您需要一个 deploy.sh bash 脚本才能在 Linux 上运行。显然没有办法在 Windows 上生成它......你需要启动你的 Linux 机器并使用

azure site deploymentscript --node

得到它。您无法从现有的 Web 应用程序下载脚本...文档错误或已过时。但你不必这样做......这里是：

#!/bin/bash

echo "Finished successfully."

现在 .deployment 文件看起来像这样...

[config]
command = bash deploy.sh

注意以下几点：

• 在deploy.sh第2步中，我注释掉了节点选择功能，直接简单的设置了node和npm命令。节点选择功能根本不起作用。
• 我添加了 deploy.sh 步骤 4 来编译 typescript。

以下是您应该知道的其他一些似乎在任何地方都没有记录的事情：

• PORT 和 SSH_PORT 环境变量包含仅有的 2 个打开的端口。这些是我的网络应用上的 8080 和 2222。
