This is already Swarm V2, there was older Swarm, which worked nice enough. It was equivalent of multi-host Docker run, which could filter based on constraints and do bin-packing, and had even support for multi host networking with etcd/consul/zookeeper.

Then, they cancelled it, no more patches, no mention of it anywhere unless you know where to look.

Then they created Swarm Mode, and add the concept of "services" which sucks compared to regular run because it lacked so many options the run command had, it took more than 6 months to implement most of them.
