Docker's initial marketing consisted of posts on the blog of a fairly unpopular PAAS vendor, and some meetups in SV. I think they made some T-shirts at one point fairly early on too.
Compare that to the combined marketing budgets of HP, Dell, Rackspace, Redhat etc. I've probably had more spent on me by OpenStack marketing (taking flights & lunches etc into account) than the marketing budget of Docker prior to their recent funding round.
If you take "marketing" to mean random 3rd parties writing how they use Docker to solve actual problems, then yeah - I see a lot more of that than I do for OpenStack.

I agree Docker is easier to deploy though!
