How do I go about creating a docker file?

I need to create a Docker file for a web app which uses node.js, express.js, react, redux etc.Can someone point me a tutorial about how to create a Docker file so that I can dockerize it in a container and put it in a /xyz directory? Also, I am not sure if I need a start shell script something like that. The container will be used to deploy to the AWS ec2.I have problem in deciding what is the base file. Should it be node.js follows by the version?And also the cmd part ?Also, I want it like the Docker tutorial example once I run the image I can see the result in my browser.Thanks I’m advance for your help. Tks.
