What kubelet reserves on c3-standard-22
| Setup | Max pods | kube-reserved CPU | Memory reserved + eviction | Allocatable CPU | Allocatable memory | Memory usable |
|---|---|---|---|---|---|---|
| GKE ≤ 1.36 tiered memory reservation | 110 | 125m | 7086 Mi + 100 Mi | 21.88 | 80.98 GiB | 92.0% |
| GKE 1.37+ (Container-Optimized OS) 15 MiB × max pods + 500 MiB, CPU capped at 1 vCPU | 110 | 125m | 2150 Mi + 100 Mi | 21.88 | 85.80 GiB | 97.5% |
How these numbers are computed: reservation formulas. Check a live node with kubectl describe node → Allocatable.
