Depends on how much RAM you want to allocate for each VM.

What's wrong with the minimal configuration that K8s needs? Does not make sense to run more than that, because if your PVE host fails, everything fails. More nodes would be good if you have a PVE cluster with a lot of individual PVE nodes.

thanks for coming back.
If I understand, now I have a Proxmox ENV with 32 Go, so I can have a cluster with three nodes, 10 Go for each node.

is that will work ?

depends on the used software raid technology. If you use ZFS, then it's not possible. ZFS is configured to use half you RAM.
Your PVE also needs RAM, so I'd start with e.g. 3 nodes à 8G and see how it's going.

thanks a lot.
I will follow your suggestion.
