Question

我正在ubuntu服务器上运行docker。

这似乎是一个码头工人问题。从ubuntu安装package.json工作正常。

npm http request GET https://registry.npmjs.org/express
npm info retry will retry, error on last attempt: Error: getaddrinfo EAI_AGAIN registry.npmjs.org:443

似乎无法访问npm注册表。有什么想法吗？

Ping工作正常！

Dockerfile：

FROM node:4-slim

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

COPY package.json /usr/src/app/

RUN npm install

COPY . /usr/src/app

EXPOSE 3000

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

构建-日志：

Answer 1

这是一个连接问题，与你的代码无关，Dockerfile很好。

这可能是一个间歇性的连接问题，或者可能是网络防火墙限制，或者其他一些疯狂的IP疯狂事件。

我看到很多间歇性的连接问题，运行各种工具来从互联网上打包东西，有时它只是其中之一。

在上次尝试使用的网络上的计算机上试用。

Answer 2

这是一个网络配置问题更可能是iptables ...你设置了docker0自定义范围吗？看看那里。

Answer 3

这也是我在Windows版Docker和GitLab Windows运行器上遇到的问题。问题出在docker run上，网络可以正常工作并且能够ping /解析所有域。运行docker build时，npm会失败，并显示EAI_AGAIN错误。

解决方案

docker build具有--network=可用于Docker build docs

找到用于docker run或docker-compose项目的可用Docker网络。

查找docker网络：docker network ls
使用docker build --network=<insert network from above> -f "myproj\Dockerfile" -t app:latest上方的网络运行Docker构建

Docker无法安装npm软件包
