Node.js Web Server Deployed within Docker

Node.js is a server-side, JavaScript package, often used for various cloud applications. Docker is a container platform. With Docker, users can download applications without the hassle of the installation and configuration process.

To install Docker CE (Community Edition), follow the instructions within one of the guides below:

• Installing and Using Docker on Ubuntu and Debian

• Installing and Using Docker on CentOS and Fedora

For complete instructions on even more Linux distributions, reference the Install Docker Engine section of Docker’s official documentation.

The Docker Hub user page for Linode can be accessed here. Select the server-node-js image for configuration information.

Note

Docker images made for one operating system can be used on servers running a different OS. The server-node-js Ubuntu 14.04 image was tested on Debian 7, Ubuntu 14.04, CentOS 7 and Fedora 21. After Docker installation on CentOS and Fedora, run the sudo service docker start command.

1. Search for linode images:

   docker search linode
   

2. Download the linode/server-node-js image:

   docker pull linode/server-node-js
   

1. Run the Linode container. Forward the Linode’s port 80 to port 3000 of the container:

   docker run -d -p 80:3000 linode/server-node-js
   

   Note

   This command runs the docker image as a daemon.

2. Test the server at example.com/test.htm, replacing example.com with your Linode’s IP address. A page with “Test File” should appear.

The Docker Hub image page has information explaining what the Docker image contains.
