Version 2.12.0-applier

Added

• In-Place-Pod-Resize Support

  • To enable, set the workload’s apply.method setting to WebhookImmediateRollout or WebhookHybridRollout.
    • WebhookImmediateRollout - Use a mutating webhook to modify Pods at admission. Existing pods will be resized in place when a new recommendation is applied. If Pods cannot be resized in place, a rollout/restart will be triggered.
    • WebhookHybridRollout - Use a mutating webhook to modify Pods at admission. Existing pods will be resized in place when a new recommendation is applied. If Pods cannot be resized in place, changes will be deferred until the next rollout.

• HPA Reconciliation - Applier will watch, detect, and reconcile any drift in HPA TargetUtilization setting.

  • To enable this via helm:

reconciliation:
  mode: EventBased
  controllers:
  - resource: hpa
    enabled: true

• Restart of the Applier when the ConfigMap changes.
