The author of Fleet have started contributing a Fleet adapter :) libswarm exposes a standard interface to systems like Fleet, Mesos, Consul etc. It also has adapters for popular infrastructure providers, and for the Docker API itself. That way you can compose your architecture from standard building blocks, and change the building blocks over time without being locked in. There was huge demand for this in the Docker system because there are so many orchestration tools being announced and competing for the attention of developers and sysadmins. Just at Dockercon, New Relic announced "Centurion", Spotify announced "Helios", Google announced "Kubernetes". Having a standard interface allows for these tools to continue competing without the risk of fragmentation and lock-in. Of course the interface has to be thin enough to not get in the way. That's why we're focusing on keeping the codebase small, and the API as simple as possible.
