What happened to it?

I'm still using it with not a single issue (except when is messes up the iptables rules)

I still confidently, upgrade the docker across all the nodes, workers and managers and it just works. Not a single time that it caused an issue.

Docker the company bet big on Swarm being the de facto container orchestration platform for businesses. It just got completely overshadowed by k8s. Swarm continues to exist and be actively developed, but it’s doomed to fade into obscurity.

For some reason I assumed it was unsupported. That doesn't seem to be the case.

The original iteration of Docker Swarm, now known as Classic, is deprecated. Maybe you were thinking of that?

As I read more about it, yes, that is indeed the case.
