I have a #devops (or what we used to call #sysadmin) question...

I like Docker Swarm for its simplicity and apparent "lightweight" nature. From a user standpoint, you can simply define a set of services and it's not that much of a leap to go from a docker-compose file to a full blown distributed system for a small number f nodes.

The problems are that Docker Swarm only appears to be offered by Docker (tm) and requires the real Docker (tm) stack, as opposed to the solution most distros use today, which is to use podman as a Docker replacement (for many good reasons).

And the fact that Docker is owned by Mirantis, Mirantis's future seems uncertain is good reason not to stay.

Is anyone still using Docker Swarm? If not, do you have a lightweight alternative (not Kubernetes)? I've heard not-great things about Nomad.

I feel like this is a huge missing area in the orchestration landscape.
