Usage

Enabling AutoVPA for all namespaces

To enable the AutoVPA controller for all namespaces in the cluster, set settings.autovpa.enabled to true without specifying additional filters:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: adaptive-resource-management
spec:
  version: 1
  enabled: true
  settings:
    autovpa:
      enabled: true

In this mode, AutoVPA creates VPA objects for workloads in every namespace.

Enabling AutoVPA for specific namespaces using a label selector

To limit AutoVPA to namespaces matching a label selector, use the namespaceLabelSelector parameter:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: adaptive-resource-management
spec:
  version: 1
  enabled: true
  settings:
    autovpa:
      enabled: true
      namespaceLabelSelector:
        matchLabels:
          env: prod

AutoVPA will only manage namespaces that have the env: prod label.

Enabling AutoVPA for namespaces with a special label

To manage only namespaces explicitly marked with the autovpa.deckhouse.io/enabled: "true" label, use the onlySpecialLabel parameter:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: adaptive-resource-management
spec:
  version: 1
  enabled: true
  settings:
    autovpa:
      enabled: true
      onlySpecialLabel: true

Then add the label to the desired namespaces:

d8 k label namespace my-namespace autovpa.deckhouse.io/enabled=true

Combining a label selector with the special label

When both onlySpecialLabel and namespaceLabelSelector are set, the resulting list of managed namespaces is the union of both sets:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: adaptive-resource-management
spec:
  version: 1
  enabled: true
  settings:
    autovpa:
      enabled: true
      onlySpecialLabel: true
      namespaceLabelSelector:
        matchLabels:
          team: backend

In this example, AutoVPA will manage namespaces that either have the team: backend label or the autovpa.deckhouse.io/enabled: "true" label (or both).
