# Example
REPOSITORY                          TAG           ID            CREATED
node                                10            1934b0b038d1  5 days ago
<your username>/docker-node-app     latest        d64d3505b0d2  1 minute ago

Run the image

Run your image with the following command:

docker run -it -d -p 9000:8080 <your username>/docker-node-app

-d flag runs application in detech mode, that means running the container in the background and -p flag redirects the public port 9000 to the private port 8080 inside the docker container.

if you wish to go inside the container, you can use following command:

# Enter in the container
$ docker exec -it <container id> /bin/bash

To test your app, open http://localhost:9000 inside your browser.
