Run with Docker

Pull Project

Pull Docker image from Docker Hub.

$ docker pull andy6804tw/docker-nodejs-tutorial

Run the image

Running your image with -d runs the container in detached mode, leaving the container running in the background. The -p flag redirects a public port to a private port inside the container. Run the image you previously built.

$ docker run -p 3000:8080 -d  andy6804tw/docker-nodejs-tutorial

Test

Docker mapped the 8080 port inside of the container to the port 3000 on your machine.

$ curl -i localhost:3000
