The docker ecosystem is hard to follow. Like you've just mentioned there are multiple solution to each problem. Docker based solutions for orchestration(Swarm), storage (v1.9) and networking (v1.9) overlap with the offerings from Kubernetes,Mesos, Flocker and whole bunch of others.

It's hard to know whether to wait for Docker to provide a solution or to use something that already has momentum. Take networking for example. Solutions have been bandied about for the last year or so and only now do we have something that's production ready. Do I rip out what I already have for something that is docker native or do I continue with the community based solution.

Storage (Data Locality) also follows a similar path. Kubernetes provides a way for making network based storage devices available to your containers. But now, with the announcement of Docker v1.9 do I go with their native solution or something that has been around for ~6months longer?

I've been working with these technologies for the past year and it has not been easy building something that is stable with a reasonable amount of future-proofness baked in.

My advice would be to think hard about your requirements and pick something which meets them. Don't fret about the "best" solution - you and your team have more important problems to solve. If something works for you then you have made the right choice. All the solutions you would pick today will still be around tomorrow.
