Download the Docker Node.js Server Image
The Docker Hub user page for Linode can be accessed here. Select the server-node-js image for configuration information.
NoteDocker 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 thesudo service docker startcommand.
Search for linode images:
docker search linodeDownload the linode/server-node-js image:
docker pull linode/server-node-js
Run the Docker Container, Node.js, and the Web Server
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-jsNote
This command runs the docker image as a daemon.Test the server at
example.com/test.htm, replacingexample.comwith 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.
