$ docker run hello-world

--- you should see ---

Hello from Docker.

This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:

 1. The Docker client contacted the Docker daemon.

 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.

 3. The Docker daemon created a new container from that image which runs the

    executable that produces the output you are currently reading.

 4. The Docker daemon streamed that output to the Docker client, which sent it

    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:

 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker Hub account:

 https://hub.docker.com

How To Install nodeJs Using a PPA

An alternative that can get you a more recent version of Node.js is to add a PPA (personal package archive) maintained by NodeSource. This will probably have more up-to-date versions of Node.js than the official Ubuntu repositories.

First, you need to install the PPA in order to get access to its contents:

curl -sL https://deb.nodesource.com/setup | sudo bash -

The PPA will be added to your configuration and your local package cache will be updated automatically. After running the setup script from nodesource, you can install the Node.js package in the same way that you did above:

sudo apt-get install nodejs

The nodejs package contains the nodejs binary as well as npm, so you don't need to install npm separately. However, in order for some npm packages to work (such as those that require building from source), you will need to install the build-essentials package:

sudo apt-get install build-essential
