c6g.4xlarge EKS max pods and allocatable memory — quick answers
- How many pods can a c6g.4xlarge run as a node with EKS, VPC CNI default (ENI limit)? Up to 234; kubelet keeps 2929 MiB of memory and 110m CPU, leaving 29.14 GiB and 15.89 vCPU for pods.
- How many pods can a c6g.4xlarge run as a node with EKS, prefix delegation? Up to 110; kubelet keeps 1565 MiB of memory and 110m CPU, leaving 30.47 GiB and 15.89 vCPU for pods.
- How many 500m / 1 GiB pods fit? 28 per node after DaemonSets; 1 nodes for 10 replicas, about $397.12/month on demand.
What kubelet reserves on c6g.4xlarge
| 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 | 234 | 110m | 2829 Mi + 100 Mi | 15.89 | 29.14 GiB | 91.1% |
| EKS, prefix delegation ENABLE_PREFIX_DELEGATION=true | 110 | 110m | 1465 Mi + 100 Mi | 15.89 | 30.47 GiB | 95.2% |
How these numbers are computed: reservation formulas. How many subnet IPs a c6g.4xlarge takes with the VPC CNI: EKS max pods and IP calculator. Check a live node with kubectl describe node → Allocatable.
