问题描述

使用docker使用npm构建镜像的时候报错如下：

npm ERR! code EAI_AGAIN
npm ERR! errno EAI_AGAIN
npm ERR! request to https://registry.npmjs.org/grunt failed, reason: getaddrinfo EAI_AGAIN registry.npmjs.org registry.npmjs.org:443

npm ERR! A complete log of this run can be found in:
npm ERR!     /root/.npm/_logs/2018-08-21T09_16_04_593Z-debug.log

解决过程

1. Dockerfile中加入RUN npm install -g cnpm --registry=http://r.cnpmjs.org，后面的npm全改为cnpm。结果失败了，依然报错。
2. 在stackoverflow找到同样问题，sudo service docker restart，成功。

后续问题

Error making request.
Error: connect ETIMEDOUT 54.231.120.211:443
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1161:14)

显然超时了，再把解决过程1的操作加上，终于成功了。
