Kubernetes Pod Resource Request vs Limit Calculator
Estimate node packing density and CPU/memory headroom from pod resource requests, limits and node capacity.
Your inputs
Change any value to update the result instantly.
Max pods per node
32 pods
Max pods by CPU
32
Max pods by memory
128
Binding constraint
1
Node CPU (millicores)
16,000 m
The CPU request is the binding constraint on this node.
Formula and working
Pods per node = floor(node capacity ÷ pod request), for each of CPU and memory (binding constraint wins)
- 1
Collect the inputs
Node allocatable CPU (cores) = 16 cores; Node allocatable memory (GB) = 64 GB; Pod CPU request (millicores) = 500 mCPU; Pod memory request (MB) = 512 MB
- 2
Apply the formula
Pods per node = floor(node capacity ÷ pod request), for each of CPU and memory (binding constraint wins)
- 3
Result
Max pods per node = 32 pods
