Any opinions on Cozystack? - eviltoast

I’ve been thinking of migrating from proxmox to a kubernetes (talos) + kubevirt set up. I recently discovered https://cozystack.io/ which seems like it combines a lot of the things I would have to set up anyway.

Anybody have any experience with it? Curious to hear if it works well or if there are any major caveats/gotchas vs a more DIY setup.

    I haven’t come across this before. Interesting
    I like this Talos idea of an ESXi-like minimalist hypervisor. A hypervisor should be a black box, just deliver services, no extra stuff.

    It’s interesting that in order to stand up a lab, you have to have 3 nodes for a cluster. Our Unix team uses Kubernetes at work, but I’ve got limited exposure. I don’t recall needing a cluster when I worked with it before.

    This is a very interesting system, but its built around a new security model that looks like it might take some getting used to. https://cozystack.io/docs/guides/concepts/

      I really like Talos (and Omni from the same people). I’ve tried a few different kubernetes-specific distros and Talos seems pretty good. It’s really lightweight in what it comes with by default. It’s also nice that I don’t need to really manage the nodes themselves - I can create yaml “patches” to set things like sysctl options or iptables rules instead of having to also set up something like ansible to manage the nodes.

      Cozystack adds a bunch of stuff on top, I haven’t had a chance to try it out yet though.

      I think the 3-node requirement is mostly for etcd. It’s possible to have a 1 or 2 node cluster, you just won’t have the same HA redundancy for the control plane.
