What kubelet reserves on a2-ultragpu-2g
| Setup | Max pods | kube-reserved CPU | Memory reserved + eviction | Allocatable CPU | Allocatable memory | Memory usable |
|---|---|---|---|---|---|---|
| GKE ≤ 1.36 tiered memory reservation | 110 | 130m | 13885 Mi + 100 Mi | 23.87 | 326.34 GiB | 96.0% |
| GKE 1.37+ (Container-Optimized OS) 15 MiB × max pods + 500 MiB, CPU capped at 1 vCPU | 110 | 130m | 2150 Mi + 100 Mi | 23.87 | 337.80 GiB | 99.4% |
How these numbers are computed: reservation formulas. Check a live node with kubectl describe node → Allocatable.
