I've noticed the same trend, and as a fan of Docker Swarm, along with this news, I'm not happy about it.

Compared to Kubernetes, Swarm is a breeze to setup, deploy and manage. The manifest files are the same Docker Compose files we're used to, just expanded to cover the new stack concepts. It has support for remote storage mounting, advanced networking configuration, various interesting volume and network plugins[0], and is generally a pain-free experience to use (from my admittedly short time with both).

Kubernetes is a fine product. It's just a shame Swarm doesn't seem to have the same traction.

Can someone share their Swarm experience in production, possibly compared to k8s?

> Well, "won" in quotes. I am not a k8s fanboy or anything, I simply observe that all the major cloud providers are offering managed k8s services that have superseded their own proprietary container-type offerings. For better or worse that's where the momentum is. If you wanted to containerize your stack right now, k8s then pick one of the big 3, seems like a safe bet.

kubernetes got released more than a year earlier. And it wasn't until 2016 that people actually started to take docker-swarm seriously. Thats a two year headstart...

docker-swarm would've needed several really impactful feature to offset that. It didn't really. The only real upsite is how easy it is to install and maintain. But that's hardly important with pretty cheap hosted solutions around (at least cheap in comparison to hiring several SRE to maintain the cluster).

But thats just my opinion as a user.
