Add Node.js on Docker guide

[Starefossen]

A simple guide to show the user how to get a Node.js application running in a Docker container using the official Docker Image for Node.js. It assumes a working installation of Docker and rootamentary understanding of how a Node.js application is structured.

• short intro to Docker?
• create a simple Node.js web application
• build a Docker Image for the application
• run the Docker Image as a container
• where to get help?

This is based on the Node.js Web App guide at doc.docker.com.

Nice, looking forward to it!

added some minor nitpicks, but otherwise it looks nice

Worth mentioning towards the bottom that if you want to enter the container to take a look around you can with the exec command docker exec -it <container id> bash ?

This is super slick @Starefossen :-)

I have a similar writeup here for both Docker and docker-compose: https://nodesource.com/blog/dockerizing-your-nodejs-applications

I have been thinking about turning this into a blog post for a while. Perhaps it would make a better wiki? I'd like to see something focused on using Docker and docker-compose for local dev. If you think this is a good fit, I'll draft something up 😄

Thanks for good feedback! I have updated the guide with everything suggested so far. There are two todos lest; intro to docker and where to get help.

@wblankenship I have not had Node installed on my computer for the past year, I have been running everything through Docker Compose! I feel Compose may be a bit much/advanced for this guide, I would definitely like to see that go into a wiki or a separate guide!

Suggestions:

• official documentation: https://docs.docker.com/
• docker tag on stack overflow: http://stackoverflow.com/questions/tagged/docker
• docker subreddit: https://reddit.com/r/docker

[Starefossen]

Thanks for the suggestions @rnsloan. I have pushed a new version.

[Starefossen]

I am pretty happy with the current version of the Node.js on Docker guide now. Please, nitpick and correct my spelling mistakes if you find anything, and post your suggestions on how to improve this guide.

use ```bash instead of indentation?

☑️ Fixed

[Starefossen]

Well, I guess all the suggestions and feedback have been resolved. It should be good to merge now :)

It would be a shame if we didn't link to this anywhere. Guess adding a link in our guides section /docs/guides/ would be most appropriate.
