Your article mentions the reason you chose client code vs docker images, which I understand and can agree with. However, is there any plan to support docker images in place of client code?

What you're suggesting [initially] is very similar to what the folks at iron.io did but I'd really want to ship containers all around, not pieces of code. Iron.io addressed that a little too late in my opinion and their feature set around docker leaves a lot to be desired.

IMO, AWS Lambda and Google Cloud Functions are going to support docker in the near future, they have to if they want their ecosystem to be adoptable by all.
