This is great @strues

Thanks!

I am a bit of a docker noob, so I am gonna let this PR sit for a while until I wrap my head around it. I definitely would like us to explore the production use case a bit further too.

What do you see as the major advantages of using the docker container during development vs the "standard" method?

[strues]

@ctrlplusb I feel like Docker in this case is slightly unnecessary, but thats just my opinion. I know a lot of people use Docker for everything in development. I usually only run my databases in containers until production.

[ctrlplusb]

@strues I would have to agree. I can't see the obvious value in running docker in development.

Lets keep this running though. I am definitely interested in a "production" container configuration.

@strues Wondering if you are maintaining a docker version in your own work for react-universally? If yes, could you share your docker config?

I use Dokku myself with React Universally. Curious to understand the difference in use cases, advantage, disadvantage?
