Vertical Pod Autoscaling

Vertical Pod Autoscaling (VPA) automatically adjusts CPU and memory requests based on actual usage. This helps keep pods right-sized without manual tuning.

Cosmopilot can configure VPA for a ChainNode or the validator within a ChainNodeSet.

Example

spec:
  vpa:
    enabled: true
    cpu:
      cooldown: 30m
      min: 750m
      max: 8000m
      rules:
        - direction: up
          usagePercent: 90
          duration: 5m
          stepPercent: 50
        - direction: down
          usagePercent: 40
          duration: 30m
          stepPercent: 50
    memory:
      cooldown: 30m
      min: 4Gi
      max: 32Gi
      rules:
        - direction: up
          usagePercent: 90
          duration: 5m
          stepPercent: 75
        - direction: down
          usagePercent: 40
          duration: 30m
          stepPercent: 50

In this example the ChainNode defines CPU and memory scaling rules for its pods.

Notes

• VPA requires a Vertical Pod Autoscaler controller running in the cluster.
• If enabled is set to false, pods keep their configured CPU and memory requests without vertical autoscaling.
