Sure, it's stable enough, just keep in mind you won't get any autoscaling (or manual for that matter). Swarm is still supported by a third party, but that party has been loudly signaling that they intend to kill it off this year or next. Kubernetes isn't too big a leap, but damn are all those yaml manifests annoying to maintain. I usually just copy and tweak them from another project.
