c4n-highmem-2 GKE max pods and allocatable memory — quick answers
- How many pods can a c4n-highmem-2 run as a node with GKE ≤ 1.36? Up to 110; kubelet keeps 2660 MiB of memory and 70m CPU, leaving 12.40 GiB and 1.93 vCPU for pods.
- How many pods can a c4n-highmem-2 run as a node with GKE 1.37+ (Container-Optimized OS)? Up to 110; kubelet keeps 2250 MiB of memory and 70m CPU, leaving 12.80 GiB and 1.93 vCPU for pods.
- How many 500m / 1 GiB pods fit? 3 per node after DaemonSets; 4 nodes for 10 replicas, about $599.75/month on demand.
What kubelet reserves on c4n-highmem-2
| Setup | Max pods | kube-reserved CPU | Memory reserved + eviction | Allocatable CPU | Allocatable memory | Memory usable |
|---|---|---|---|---|---|---|
| GKE ≤ 1.36 tiered memory reservation | 110 | 70m | 2560 Mi + 100 Mi | 1.93 | 12.40 GiB | 82.7% |
| GKE 1.37+ (Container-Optimized OS) 15 MiB × max pods + 500 MiB, CPU capped at 1 vCPU | 110 | 70m | 2150 Mi + 100 Mi | 1.93 | 12.80 GiB | 85.4% |
How these numbers are computed: reservation formulas. Check a live node with kubectl describe node → Allocatable.
