无法在docker容器中安装npm？ [英] can't install npm in the docker container?
问题描述
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。
I am deploying a simple node.js app on a digital ocean server 's docker platform.
// package.json
// 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
// 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
// docker file
FROM dockerfile/nodejs
# Set the working directory
WORKDIR /src
EXPOSE 3000
CMD ["/bin/bash"]
docker基本镜像是dockerfile / nodejs，它已经构建了一个node.js，我构建了该镜像：
The docker base image is the dockerfile/nodejs, which has built a node.js, I built the image:
docker build -t test1 /home/sizhe/docker/test
并运行映像：
docker run -it -p 8080:3000 -v /home/sizhe/docker/test1:/src test
通过运行映像，我可以成功放入容器中，将应用程序文件全部复制到容器中。当我尝试使用命令安装node.js依赖项时：
By running the image, I can successfully into the container, the app files are all copied into the container. when I tried the command to install the node.js dependency:
npm install
但是，npm无法下载所有软件包，但出现错误：
However, npm can't download all the packages, with a error:
Linux 3.13.0-40-generic

推荐答案
确保dns设置正确。 docker 服务重启后，我遇到了一些问题。如果没有帮助，您可能需要使用-dns 8.8.8.8 泊坞窗开关。
Make sure the dns is set properly. I had some issues that were gone after the docker service restart. If it didn't help you may want to use the --dns 8.8.8.8 docker switch.
重新启动docker服务：
Restarting docker service:
- 基于systemd架构-
sudo systemctl restart docker - boot2docker-
boot2docker restart - Docker Machine-
docker-machine restart< machine_name>
- on systemd architecture -
sudo systemctl restart docker - boot2docker -
boot2docker restart - Docker Machine -
docker-machine restart <machine_name>
我也做了类似的事情（nodejs图像），但是我使用了另一个基础图片，请随时使用我的 repo 中的任何内容。
Also, I did something similar (nodejs image), but I've used another base image, feel free to use whatever you need from my repo.
