AI Analysis

●●SolidNiche GemBig Brain

Read-only rebalance advisor with constraint-aware planning beats manual kubectl debugging.

Strengths

•Full constraint awareness handles affinity, anti-affinity, taints, and DaemonSets correctly
•Node failure simulation shows which pods become homeless before disasters happen
•Move explanations detail why each suggestion was chosen and which nodes were rejected

Weaknesses

•K8s optimization tools like Goldilocks and VPA already exist in this space
•Zero stars at time of posting suggests very early stage with limited real-world testing

Post Description

Hi HN,

I built hanoi-cli, a small CLI tool that analyzes how pods are distributed across Kubernetes nodes and suggests a better placement.

The idea came from a recurring issue: clusters often end up imbalanced even when requests/limits are set properly. Some nodes get overloaded while others stay underutilized.

Would love feedback.
