m8azn.3xlarge EKS max pods and allocatable memory — quick answers
- How many pods can a m8azn.3xlarge run as a node with EKS, VPC CNI default (ENI limit)? Up to 314; kubelet keeps 3809 MiB of memory and 100m CPU, leaving 44.28 GiB and 11.90 vCPU for pods.
- How many pods can a m8azn.3xlarge run as a node with EKS, prefix delegation? Up to 110; kubelet keeps 1565 MiB of memory and 100m CPU, leaving 46.47 GiB and 11.90 vCPU for pods.
- How many 500m / 1 GiB pods fit? 23 per node after DaemonSets; 1 nodes for 10 replicas, about $904.29/month on demand.
What kubelet reserves on m8azn.3xlarge
| Setup | Max pods | kube-reserved CPU | Memory reserved + eviction | Allocatable CPU | Allocatable memory | Memory usable |
|---|---|---|---|---|---|---|
| EKS, VPC CNI default (ENI limit) secondary IPs per ENI | 314 | 100m | 3709 Mi + 100 Mi | 11.90 | 44.28 GiB | 92.3% |
| EKS, prefix delegation ENABLE_PREFIX_DELEGATION=true | 110 | 100m | 1465 Mi + 100 Mi | 11.90 | 46.47 GiB | 96.8% |
How these numbers are computed: reservation formulas. How many subnet IPs a m8azn.3xlarge takes with the VPC CNI: EKS max pods and IP calculator. Check a live node with kubectl describe node → Allocatable.
