Depending on what you're going to do with the cluster, 4gb of RAM per node feels rather limiting.
Anyways, as far as storage goes I'm using 4 compute blades loaded with 4 8gb RAM versions of the CM4, each with a 500gb Samsung PM9A1 running Talos to save a bit on that precious RAM.
Got Talos up and running with some help from Onedr0p's cluster template which saved me a lot of time on the learning curve.
Ooh, Onedr0p's cluster template looks great so tried it but getting stuck on RPI_EFI.fd
The notes say: create RPI_EFI.fd like here https://www.sidero.dev/v0.6/guides/rpi4-as-servers/#persisting-changes
But that requires setting up sidero which is discontinued and looks like it needs a working talos cluster to get it working anyway, so is there an easier way to generate RPI_EFI.fd ?
I’m also hitting other issues so going to have to wipe the pi I have for PXE anyway so maybe it’ll play nice after a reset. 🤔
I initially generated the talos config with the template script, but using talhelper directly offers a bit more flexibility. The first four nodes in this list are the cm4's

I also wrote down my setup steps, check here:
