c4a-highcpu-1 GKE max pods and allocatable memory — quick answers
- How many pods can a c4a-highcpu-1 run as a node with GKE ≤ 1.36? Up to 110; kubelet keeps 612 MiB of memory and 60m CPU, leaving 1.40 GiB and 0.94 vCPU for pods.
- How many pods can a c4a-highcpu-1 run as a node with GKE 1.37+ (Container-Optimized OS)? Up to 110; kubelet keeps 612 MiB of memory and 60m CPU, leaving 1.40 GiB and 0.94 vCPU for pods.
- How many 500m / 1 GiB pods fit? 1 per node after DaemonSets; 10 nodes for 10 replicas, about $276.52/month on demand.
What kubelet reserves on c4a-highcpu-1
| Setup | Max pods | kube-reserved CPU | Memory reserved + eviction | Allocatable CPU | Allocatable memory | Memory usable |
|---|---|---|---|---|---|---|
| GKE ≤ 1.36 tiered memory reservation | 110 | 60m | 512 Mi + 100 Mi | 0.94 | 1.40 GiB | 70.1% |
| GKE 1.37+ (Container-Optimized OS) 15 MiB × max pods + 500 MiB, CPU capped at 1 vCPU | 110 | 60m | 512 Mi + 100 Mi | 0.94 | 1.40 GiB | 70.1% |
How these numbers are computed: reservation formulas. Check a live node with kubectl describe node → Allocatable.
