# Node.js

## 基本訊息

[Node.js](https://en.wikipedia.org/wiki/Node.js)是基於 JavaScript 的可擴展服務端和網路軟體開發平台。 該倉庫提供了 Node.js 0.8 \~ 0.11 各個版本的映像檔。

## 使用方法

在專案中建立一個 Dockerfile。

```
FROM node:0.10-onbuild
# replace this with your application's default port
EXPOSE 8888
```

然後建立映像檔，並啟動容器

```
$ sudo docker build -t my-nodejs-app
$ sudo docker run -it --rm --name my-running-app my-nodejs-app
```

也可以直接執行一個簡單容器。

```
$ sudo docker run -it --rm --name my-running-script -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp node:0.10 node your-daemon-or-script.js
```
