npm 安装时 docker 构建失败，原因：connect ECONNREFUSED 104.16.17.35:443

Question

我在启动 Docker 容器时遇到了困难，它在控制台中显示了一些奇怪的错误，因为我是新手，所以我对它的线索为零：

Dockerfile：

FROM node:14

WORKDIR /usr/src/app/

COPY package.json package.json
COPY server.js server.js

RUN ping -c 4 google.com
RUN  npm config set registry https://registry.npmjs.com/
RUN echo "${http_proxy}" && echo "${HTTP_PROXY}" 

RUN npm install
# COPY . .

EXPOSE 3000

CMD ['npm', 'start']

当我运行 docker build 命令时

$ docker build -t myapp .

我收到的错误：

我使用的是 Ubuntu 20.4，它只是一个带有 server.js 文件的简单节点应用程序。如果您需要我提供任何其他信息来修复它，请告诉我。预先感谢您的帮助！

docker 网络、代理或防火墙似乎有问题。它可以通过指定来修复--network="host"

$ docker build -t myapp . --network="host"

繁荣它开始像魅力一样发挥作用！
