Docker构建npm安装错误网络超时

Question

我尝试将映像构建到节点应用程序，但是当我执行 docker build 时显示运行 npm install 时出现错误

npm 错误！网络超时：https://registry.npmjs.org/cookie/-/cookie-0.4.0.tgz

关注 docker 文件内容：

FROM node:13

# Create app directory
WORKDIR /usr/src/app

# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./

RUN npm install
# If you are building your code for production
# RUN npm ci --only=production

# Bundle app source
COPY . .

EXPOSE 8080
CMD [ "node", "server.js" ]

关注我的 package.json

{
  "name": "backend",
  "version": "1.0.0",
  "description": "",
  "private": true,
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],

  "dependencies": {

    "express": "^4.17.1",
    "request": "^2.88.2",
    "xml2js": "^0.4.23"
  }
}

操作系统版本：CentOS Linux 版本 8.1.1911（核心）

Docker 版本：Docker 版本 19.03.8，构建 afacb8b

Answer 1

[已解决]问题出在docker网络中，然后我执行了以下命令：

docker build -t cassiamani/nodeapp --network=host .

--network=host 使用主机的 dns，对我来说它有效。
