According to the docs, k8s can support systems of up to 150000 pods.
(See https://kubernetes.io/docs/admin/cluster-large/) But given k8s'
networking model, I'm a bit puzzled on how that would work.
It seems like a typical setup is to assign a service-cluster-ip-range
with a /16 CIDR. (Say 10.254.0.0/16) However, I notice that my cluster
assigns a full /24 IP range to each pod that it creates. (E.g., pod1
gets 10.254.1.*, pod2 gets 10.254.2.*, etc.) Given this networking
setup, it would seem that Kubernetes would only be capable of launching
a maximum of 256 pods.
Am I misunderstanding how k8s works in this r? Or is it that the
networking would need to be configured differently to support more than
256 pods?
Thanks,
DR
