无法在 docker 容器中安装 npm?

can't install npm in the docker container?

我正在数字海洋服务器的 docker 平台上部署一个简单的 node.js 应用程序。

// package.json

{
  "name": "docker-centos-hello",
  "private": true,
  "version": "0.0.1",
  "description": "Node.js Hello world app on CentOS using docker",
  "author": "Daniel Gasienica <daniel@gasienica.ch>",
  "dependencies": {
    "express": "3.2.4"
  }
}

// app.js

var express = require('express');
var PORT = 3000;
var app = express();
app.get('/', function (req, res) {
  res.send('Hello world\n');
});  
app.listen(PORT);
console.log('Running on http://localhost:' + PORT);

// docker 文件

FROM dockerfile/nodejs
# Set the working directory
WORKDIR   /src
EXPOSE  3000
CMD ["/bin/bash"]

docker基础镜像是dockerfile/nodejs,构建了一个node.js,我构建的镜像:

docker build -t test1 /home/sizhe/docker/test

和运行图像:

docker run -it -p 8080:3000 -v /home/sizhe/docker/test1:/src test

通过运行ning镜像,我可以成功的进入容器,app文件都被复制到容器中了。当我尝试安装 node.js 依赖项的命令时:

npm install

但是npm无法下载所有包,报错:

确保dns设置正确。 docker 服务重启后,我遇到了一些问题。如果它没有帮助,您可能需要使用 --dns 8.8.8.8 docker 开关。

正在重新启动 docker 服务:

  • 在 systemd 架构上 - sudo systemctl restart docker
  • boot2docker - boot2docker restart
  • Docker 机器 - docker-machine restart <machine_name>

此外,我做了类似的事情(nodejs 图像),但我使用了另一个基础图像,请随意使用我的 repo.

中的任何你需要的东西
