I am particularly happy with docker swarm with traefik as described here: https://dockerswarm.rocks/traefik/

Incredibly easy to setup and manage for usual small scale deployments. I use it as one node swarms, and I have setup - backups - automatic https certificates setup and renewal - automatic upgrades to new images - easy setup of persistence of data on the server

I'm very surprised it is not more popular, with quite some people trying to replicate swarm's features with docker compose, but often in harder to maintain setups.

Looks like https://dockerswarm.rocks says that the site is deprecated.

https://dockerswarm.rocks/swarm-or-kubernetes/ says "it's not sensible to build a new product using Docker Swarm Mode"

That's indeed the opinion of the author. Note however that at this time all elements used in the setup described on dockerswarm.rocks are maintained. I started using swarm in 2022 and I documented my decision [1], and my reasoning for my kind of needs as not changed. The investment is very low, as well as the risk. Migrating away from swarm should not be very problematic for me, and in the meantime I enjoy an easy to maintain setup. I still think it's better than tweaking a maybe working solution with compose.

I'm not expecting to convince anyone but wanted to share an alternative approach(only applicable to certain setup)

I love Swarm and don't see the appeal of K8s when something as simple as Swarm exists. I do however run K8s in prod for work and would never run Swarm in prod due to Docker seeming to have its days numbered. Idk where that leaves us aside from ECS. But I also have no need to run something any more robust than ECS in AWS for my workload.

We are moving our EKS workload over to ECS over the next year. I expect needing to down size my team because of it.

One thing K8s is not is cheap. That shit takes a well oiled team or a couple of hot shots so do right. We probably did a lot of what makes it expensive to ourselves by not switching to managed add-ons sooner and never evolving the apps that run in the cluster. I've only been lead for about 5 months now, but I'm finally able to start making significant progress on the necessary evolution that I've been trying to make happen for 2 years before my promotion. The enterprise is a big ship. Takes time to turn. Thanks for reading what turned into a rambling vent session.

I agree it depends on the situation, but there still are some situations (like small apps) where I see swarm as the way to go. Yours is probably different.
