There were two swarm's, the swarm classic — which was okayy, & then the newer swarm Mode, introduced in docker 1.12. I'm not sure which one you refer to when you say v0.4. But swarm mode was good, extremely simple & worked well for the right workloads. Like most solutions it is not a silver bullet for every orchestration need, but worked very well in microservices, new-ish architectures. K8s is great too, but it seems like an overkill for a handful of services. Also setup of K8s used to be hard, especially HA. The learning curve is also quite steep. One of the features in swarm mode that makes docker swarm extremely intuitive — IPVS, is being incorporated in K8s. So I guess there has been some cross pollination on both sides. But I do not think the swarm mode is going to die anytime soon.
