Im using multiple computers currently running docker, I don't quite
understand docker swarm but im looking for a implementation that is
open source and  overall  very good for container management, ideally
i would like the containers to all think they are on the same
computer, if docker swarm is the best option where is the best
learning rescource.

Take a look at Coolify

depending on your use case, it might be worth learning k3s - basically
a more supported docker swarm. it’s a bit harder to get up and running
compared to docker, but you can do a lot of cool stuff with it.

>think they are on the same computer

k3s with kubevip may work for you - you can have containers
distributed amongst many computers (nodes), but to computers outside
of the cluster it just looks like one machine.

You could deploy a Kubernetes cloud using Kubrspray.
The learning curve is steep bit rewarding.

For Container mgmt on docker is Portainer the Solution
Otherwise lern k8s With rke2 or k3s

If you're wanting a **learning** resource (rather than having it "Just
Work"), may I offer https://geek-cookbook.funkypenguin.co.nz/docker-
swarm/ ? It's my opinionated process on building out a swarm, much
like you describe :)

Just have a look at Nomad.

Had a single docker machine before, and wanted to upgrade to a more
distributed setup. Works like a charm now 😀

IMHO Nomad is in the sweet spot between Docker and K8s: more capable
than docker, but still not the mess of disparate moving parts that is
K8s.

or just use k3s

You could. Doing that will put some limits on you as k3s is kubernetes
with a lot of things removed.

If you don't want to use kubespray, you can still give a try to RKE2
which is k3s on steroids.
