Parameter examples and reference

resources and resourcesPreset

resources sets explicit CPU and memory configurations for each replica. When left empty, the preset defined in resourcesPreset is applied.

resources:
  cpu: 4000m
  memory: 4Gi

resourcesPreset sets named CPU and memory configurations for each replica. This setting is ignored if the corresponding resources value is set.

Preset name	CPU	memory
`nano`	`100m`	`128Mi`
`micro`	`250m`	`256Mi`
`small`	`500m`	`512Mi`
