Wonder if some old netbooks could be used for this purpose. Doubt I am the only one with a small pile of them laying around.

- ricardbejarano 7y agoFrom experience, anything with 2GB or more RAM can be a master node. Workers can even have 1GB and work just fine. Be warned, though, in my experience etcd requires a somewhat decent read/write latency, or else it's going to fail, and when etcd fails everything fails. Your changes don't apply, etc.
- geerlingguy 7y ago_Technically_ 1GB is the limit, but yeah, at 1GB I was hitting OOM errors every day or so (this was on the Pi 3 B+). I was very happy when I found out the Pi 4 had 2 or 4GB models! No matter what, you should also make sure to not schedule Pods on the master node(s) when you have limited memory (or in most cases, really...).
- ricardbejarano 7y agoOr set tight resource limits. Setting resource requests also enables the use of HorizontalPodAutoscalers.
- geerlingguy 7y agoVery true. The Pi Dramble's web pods are set to scale using the HPA.
