r9gd.48xlarge EKS max pods and allocatable memory — quick answers
- How many pods can a r9gd.48xlarge run as a node with EKS, prefix delegation? Up to 250; kubelet keeps 3105 MiB of memory and 550m CPU, leaving 1,532.97 GiB and 191.45 vCPU for pods.
- How many 500m / 1 GiB pods fit? 247 per node after DaemonSets; 1 nodes for 10 replicas, about $11,225.41/month on demand.
What kubelet reserves on r9gd.48xlarge
