I’ve never actually used swarm so I could be wrong. However, I was under the impression that Docker swarm is a lot easier to use with a lot more examples for people to deploy their Containers.

With K8s/K3s I find myself translating a lot of docker examples into deployment yamls with Services, Network Policies, PVCs, secrets, etc, etc. It’s just a lot more lines in the .yml files. This also assumes you know that anything that you run in docker you can run in K8s with 1 replica and more is not ideal.
