*I have tried [hello world node.js with docker](http://docs.docker.io/en/latest/examples/nodejs_web_app/#nodejs-web-app). I have created an image & container. I exported the container using*

```
docker export $container_ID > container_ID.tar

```

**Q. How to run it after importing it back ?**

```
docker import - <user-name>/node-hello < container_ID.tar
docker run -p 49610:8080 -d <user-name>/node-hello 

```

I found a a git hub issue [import error](https://github.com/dotcloud/docker/issues/1826) 

solution given here is :

```
docker run -p 49610:8080 -d <user-name>/node-hello /someCommandToRun.sh

```

I tried adding Dockerfile commands like (ADD ./src;cd ./src;npm install ; CMD['node','./src/index.js'])
but the image fails with exit 127 

**Q. What is the command to give the node-hello-world image to run ?**
