I think the main issue is that beyond the very basic examples the new Docker 1.12 swarm features aren't really production ready. At this point there is a significant amount of tooling required to get a production cluster running with your applications. The Distributed Application Bundles (DAB) files, one of the features I was most excited about, are still marked as experimental.

Overall I think Docker is heading in the right direction, but for now Kubernetes, ECS, etc... are better solutions for orchestration. I was hoping to only use Docker for my current project, but I think I'll have to wait until the next one rolls around and Docker releases a few more updates.

"Production Ready" is a funny term. Just like any other product, docker swarm will be production ready once we see a whitepaper or writeup that details the scaffolding around it to meet some sort of SLA. I would be willing to build a production cluster of say 20-50 nodes with swarm in order to learn its intricacies. Building anything larger would have to be done incrementally with lots of monitoring and transparency.
