HorizontalPodAutoscaler

This declares one HorizontalPodAutoscaler to be managed by Inrun.

Example:

onReconcile:
  hpa:
    - name: "{{ .metadata.name }}-hpa"
      deploymentRef: "{{ .metadata.name }}"
      minReplicas: "{{ .spec.minReplicas }}"
      maxReplicas: "{{ .spec.maxReplicas }}"
      targetCPUUtilizationPercentage: "80"
      forEach:
        field: spec.services
        as: item

Lifecycle

Declare this resource under onCreate for an idempotent, one-time create: Inrun creates it on the first reconcile and leaves it untouched afterward. Set reconcile: true on the same entry to also apply it as drift correction on every subsequent reconcile. This is a shorthand for declaring the identical entry under onReconcile as well — there’s no need to do both.

Declare a resource under onDelete to run explicit cleanup before the CR’s finalizer is removed. Most resources need no onDelete entry — they are garbage-collected automatically through owner references when the CR itself is deleted.

Fields

name

Type: string

Name — HPA resource name. Default: “{{ .metadata.name }}-hpa”

namespace

Type: string

Namespace — target namespace. Default: CR namespace.

scaleTargetRef

Type: object

ScaleTargetRef — the target workload this HPA scales. Supports Deployment, ReplicaSet, StatefulSet, or any scalable resource. Supports template expressions: “{{ .metadata.name }}”

scaleTargetRef:
  apiVersion: apps/v1
  kind: Deployment
  name: "{{ .metadata.name }}-deployment"

minReplicas

Type: string

MinReplicas — minimum replica count as a string. Supports template expressions.

maxReplicas

Type: string

MaxReplicas — maximum replica count as a string. Supports template expressions.

targetCPUUtilizationPercentage

Type: string

TargetCPUUtilizationPercentage — CPU utilization target (0-100). Supports templates. When behavior.preset is set and this field is empty, the preset provides the default.

behavior

Type: object

Behavior — scale-up and scale-down behavior configuration. Set preset for a complete preset, or configure scaleUp/scaleDown explicitly. Preset and explicit fields are mutually exclusive.

behavior:
  preset: web

behavior:
  scaleUp:
    stabilizationWindowSeconds: 0
  scaleDown:
    stabilizationWindowSeconds: 300

labels

Type: map

Labels applied to HPA metadata. Values support template expressions.

reconcile

Type: boolean

Reconcile: true — also apply this declaration as drift correction on every reconcile. Equivalent to declaring the same entry under both onCreate and onReconcile. When false (default), only runs on onCreate (idempotent create).

when

Type: list

When lists conditions that must all pass for this entry to be written; see Condition. When an entry kept in sync (onReconcile, or reconcile: true) stops passing, the object it wrote is removed.

or

Type: list

Or lists conditions of which at least one must pass, alongside When.

forEach

Type: object

ForEach declares dynamic expansion over a list field. When set, one source declaration becomes N declarations — one per list element. .item and .<as> are available in template expressions within this declaration.

forEach:
  field: spec.services
  as: item

forceConflict

Type: boolean

ForceConflict, when true, sets Force: true when applying this resource, taking ownership of conflicting fields instead of returning a conflict error. Overrides the CRD-level ForceConflict setting.
