It is, but at this point it is unclear for how long Docker Swarm will be supported, see e.g. https://boxboat.com/2019/12/10/migrate-docker-swarm-to-kubernetes/ https://boxboat.com/2019/12/10/migrate-docker-swarm-to-kuber... We are actually currently in the process of migrating from Docker Swarm to k8s and I am not 100% sure that's a good idea. We will see.

    No matter what they claim, it's really not supported in the sense most commercial oss projects are. We finally switched off after a minor version introduced a segfault when adding nodes in certain conditions, and the issue was unfixed after 5 months.

      This. Docker Swarm, and by extension Docker EE / UCP, is barely in maintenance mode. Go compare the Moby and docker projects on GitHub vs kubernetes. To be clear, I use Docker Swarm in my home cluster due to simplicity and ease of use. Unfortunately that pattern hasn't scaled to the Enterprise.

  What about HashiCorp's nomad? Seems a lot simpler to manage than k8s and is actively developed.

It exists but in terms of people using it or it being actively developed, it's dead as a doornail ever since Docker was more less forced to also support kubernetes and basically gave in to the reality that world + dog was opting for kubernetes instead of swarm. They never really retired it but at this point it's a footnote in Docker releases. I've not actually encountered it in the wild in four years or so and never in a production setup.
