I like swarm. Seems like Docker is moving away from it however. At least, that's what the commit numbers say [1]. The fact that Docker integrated Kubernetes into their desktop solutions is also telling.

At this point, I would rather have a closer look at either Nomad or k3s for smaller clusters.

Swarmkit is what is being used in production and is fairly popular.

https://www.digitalocean.com/currents/june-2018/

"While @kubernetesio was most popular overall, the smallest companies (1-5 employees) use @Docker Swarm more often (41 percent use Swarm vs. 31 percent that use Kubernetes)."

Yea that's the legacy "classic" swarm from pre-2016. Docker isn't moving away from Swarm, in fact they keep adding features. See https://www.bretfisher.com/the-future-of-docker-swarm/

Last month they released https://github.com/docker/stacks for Swarm.

Also, every industry survey I've seen in the last year on orchestrator uses shows increases in overall usage of K8s and Swarm, which I consider the better measure of a project's health. (CNCF, Digital Ocean, F5, Sysdig)
