The history of the relationship between Mesos and Docker is definitely an interesting one. If memory serves right, Mesos was not keen of supporting Docker as a containerizer. The devs wanted to stick to improving the Mesos containerizer.

In the end, the community was so vocal about Docker being supported in Mesos that it happened, but the end result was not stellar by all accounts (and a bit of a nightmare to deal with on the framework side to boot).

I'm not privy to what was going at the time since I was just part of the larger Mesos community, but looking back, can't help but wonder what would have happened if they collaborated instead.
