Node.js 应用程序在本地运行但在 docker 上失败(sh : 1: rimraf: not found)

Question

我能够构建 docker 镜像，但无法让容器运行。这是 package.json:

{
  "name": "linked-versions-viewer",
  "version": "1.0.0",
  "description": "...",
  "main": "./dist/bundle.js",
  "type": "module",

  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "clean": "rimraf dist",
    "build_only": "rollup -c",
    "build": "cross-env NODE_ENV=production npm run clean && npm run build_only",
    "serve": "parcel src/index.html --port 12345",
    "start": "npm run clean && npm run serve"
  },
  "repository": {
    "type": "git",
    "url": "..."
  },
  "author": "...",
  "license": "...",
  "dependencies": {
    "antd": "^4.12.3",
    "base-widget": "...",
    "react": "^17.0.2",
    "react-dom": "^17.0.1"
  },
  "devDependencies": {
    "@types/node": "^14.14.28",
    "@types/react": "^17.0.2",
    "@types/react-dom": "^17.0.1",
    "cross-env": "^7.0.3",
    "parcel-bundler": "^1.12.4",
    "rev-hash": "^3.0.0",
    "rimraf": "^3.0.2",
    "rollup": "^2.39.0",
    "rollup-plugin-commonjs": "^10.1.0",
    "rollup-plugin-node-resolve": "^5.2.0",
    "rollup-plugin-replace": "^2.2.0",
    "rollup-plugin-terser": "^7.0.2",
    "rollup-plugin-typescript2": "^0.29.0",
    "rollup-plugin-uglify": "^6.0.4",
    "typescript": "^4.1.5"
  }
}

这是 dockerfile:

FROM node:14.17.0 as base

ENV NODE_ENV=production

WORKDIR /app

COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 8080

FROM base as production

ENV NODE_PATH=./build

CMD ["npm", "start"]

我通过运行 docker build -t testapp . 创建了镜像，并尝试使用 docker run -p 8080:8080 -d testapp 运行容器，但它总是立即退出代码为 1。这是图像的错误日志:

> linked-versions-viewer@1.0.0 start /app
> npm run clean && npm run serve


> linked-versions-viewer@1.0.0 clean /app
> rimraf dist

我尝试完全删除 rimraf 依赖项，但随后出现了类似的 parcel 依赖项错误，所以可能没有正确安装包？如果有帮助，该应用程序也是用 typescript 编写的。

不确定接下来要尝试什么。感谢您提出任何建议。

Answer 1

表格npm install docs ,

With the --production flag (or when the NODE_ENV environment variable is set to production), npm will not install modules listed in devDependencies

因为你的 base 图像中有 ENV NODE_ENV=production，所以 rimraf 和 parcel-bundler 都不是安装在您的容器内。

您的 npm start 命令正在运行 npm run clean && npm run serve。 npm run clean 使用 rimraf 模块，npm run serve 使用 parcel-bundler 模块。这就是您看到这两个错误的原因。

您可以尝试以下解决方案之一，

1. 从您的 Dockerfile 中删除 ENV NODE_ENV=production(这是最快的解决方案，但不应在生产中使用)

2. 您可以使用以下方法在容器内全局安装 rimraf 和 parcel-bundler:

   RUN npm install --global rimraf && npm install --global parcel-bundler
   

   但是，我仍然认为这不是一个好的生产就绪设置。

3. 您可以在容器内使用 npm run build 正确构建您的应用程序并提供服务。但是，我对 React 不够熟悉，无法帮助您在 Docker 上进行设置。
