I deployed Docker Swarm in a small cluster at work this year. After evaluating K8S, Nomad and Swarm it was the solution that best fit our needs (together with Portainer for graphical management and a few scripts to deploy from jenkins). The system is simple enough that it can be documented on one wiki page and when stuff goes wrong (which fortunately hasn't happened yet) there is always a way to deploy the containers manually.

Interesting. I did a similar evaluation in early 2021 and landed on microk8s as the right balance of features, ease of deployment, and not having to do much hand-rolling or other manual stuff.

I have Swarm clusters running in production too, and am planning on deploying dozens more this year. Swarm is great - if you already use Compose, then you can use Swarm with ease. It's so much simpler than k8s.

  Thirding the Docker Swarm... I wouldn't say "love", more like the "it's a piece of our infrastructure and it chugs along just fine, I guess it's cool?", which is sentiment I've rarely seen anyone express towards Kubernetes.

Just FYI that swarm is EOL

  Source? It is rather the opposite based on mirantis latest blog post on Swarm https://www.mirantis.com/blog/docker-swarm-webinar-qa-long-live-docker-swarm/ https://www.mirantis.com/blog/docker-swarm-webinar-qa-long-l... > It all stems from when Mirantis first acquired the Docker Enterprise business two years ago, they put out a blog saying, “We’re gonna support Swarm for at least two more years and we’re gonna take that time to kind of see what the need is, what the market dictates…” > Unfortunately, some third parties took that and said, “Oh, they’re only going to support it for two years and then they’re going to sunset it.” That’s not true at all. This is important to us and to our future direction. We continue to invest in it and we have lots of large enterprise customers using Swarm in production at scale.

  This is not true. Swarm is part of docker-ce and there's no deprecation warning in the documentation. To quote from there: "Docker Swarm mode is built into the Docker Engine. Do not confuse Docker Swarm mode with Docker Classic Swarm which is no longer actively developed." (https://docs.docker.com/engine/swarm/ https://docs.docker.com/engine/swarm/)
