Write a Tutorial on How to Create a Docker Image

Write a technical tutorial/blog (>250 words) documenting how you would develop, create and test a docker image to support hadoop and/or spark clusters.

The following questions could serve as a guide (but you do not have to address all of them in your tutorial).

• what base linux image do you want to start with?
• what packages do you need to install in the target container?
• what hadoop and spark files do you need to download into the target container?
• what is the best/easiest way to install those packages or download those files into the container? What options do you have?
• how do you test the above?
• how do you automate the above in a Dockerfile?
• how would you test if your image works?

Remember you are documenting the whole process, so that you can refer to it after you graduate!
