Does Podman offer anything similar to Docker Swarm? I absolutely love Swarm mode (yet to find a simpler way of organising containers over a few small nodes), but do not want to deal with Docker the company.

sadly they do not provide anything like Swarm and suggest to use k8s.

no, no orchestration, I believe use Kubernetes

  Kubernetes is a huge leap in complexity for small deployments. You can simplify it with wrappers like minikube and k3s but there's still a learning curve. It'd be nice to have a simple free alternative to Swarm.

    That would be Hashicorp Nomad.

      Honest question: Is it Nomad? Because I've literally spent a couple hours watching Hashicorp videos on Nomad, and I know how to install and secure it, but I still have no idea what TF Nomad is/does. Maybe a distributed cron, that apparently has the ability to spin up a million containers? Edit because of downvote: No, really, I'm serious. Any references to how Nomad solves the Swarm/K8s problem, because I've spent my spare time this week trying to understand it and still don't know what Nomad even is.

        Nomad is an orchestrator but with less batteries included: https://learn.hashicorp.com/tutorials/nomad/get-started-intro?in=nomad/get-started https://learn.hashicorp.com/tutorials/nomad/get-started-intr... https://www.nomadproject.io/docs/nomad-vs-kubernetes https://www.nomadproject.io/docs/nomad-vs-kubernetes

        Thanks, these help. The first video at the top of the first page of Getting Started, is one of the ones I had watched earlier this week, but on the 5th page of that it's starting to get into the meat. Still working through it, but it is seeming like the answer to "What is Nomad" is: Kind of a clustered systemd. By that I'm thinking of systemd as a whole, with it's abilities to run containers, timers, daemons and dependencies... It answers the swarm/k8s call by having a job runner that can run docker containers.

        Although outdated, and somewhat incomplete (I see no mention of postgresql for the nomad example) -this might help: https://betterprogramming.pub/dockers-voting-app-on-swarm-kubernetes-and-nomad-8835a82050cf https://betterprogramming.pub/dockers-voting-app-on-swarm-ku...

      I like Nomad, but I wish useful features weren't locked in a paid version.

Nomad comes with a Podman driver, and it is quite straightforward to install and configure.

kind (kubernetes inside docker) supports podman now

They suggest to use k8s - you can also create containers in "pods" and generate kube config files for deployment into k8s.
