[BUG] Should adjust scanner CPU request in example yaml #1062

Open lzhecheng opened 3 months ago

lzhecheng commented 3 months ago

Version of Eraser

v1.4.0-beta.0

Expected Behavior

I deployed eraser on a standard CAPZ cluster with VM size: Standard B2s (2 vcpus, 4 GiB memory) Eraser Pod should start on all Nodes.

Actual Behavior

The eraser Pod on the control plane cannot start because of OutOfcpu:

Warning  OutOfcpu  20m   kubelet  Node didn't have enough resource: cpu, requested: 1007, used: 1100, capacity: 2000

The CPU request should be smaller: https://github.com/eraser-dev/eraser/blob/v1.4.0-beta.0/deploy/eraser.yaml#L431

Steps To Reproduce

  1. Deploy a CAPZ cluster
  2. Deploy eraser

@lzhecheng you can change the cpu via deploy.resources.requests.cpu https://github.com/eraser-dev/eraser/tree/v1.4.0-beta.0/charts/eraser
