Selects the objects affected by this rule using a matchLabels label selector.

selector:
  matchLabels:
    <selector-key>: <selector-value>

Selects the namespaces affected by this rule using a matchLabels label selector.

namespaceSelector:
  matchLabels:
    <selector-key>:<selector-value>

Defines the metrics that need to be for the rule’s actions to trigger.

conditions:
  - key: "<condition-formula>"
    operator: <logical-operator>
    values:
    - "<comparator>"

Conditions compare the key field with the values field using the operator field. Condition keys can contain logic and use monitoring values.

Multiple conditions are combined using a logical AND.

Defines what action to take when the conditions are met. See Supported Actions for all actions that you can specify here.

action:
  name: <operation>
  params:
    <operation-specific-parameter>: <value>

This action is to perform resize on Kubernetes PersistentVolumeClaims (PVCs).

scalepercentage: Specifies the percentage of current PVC size by which Autopilot should resize the PVC. If not specified, the default is 50%.
maxsize: Specifies the maximum threshold size in bytes after which Autopilot should stop resizing the PVCs. Note that you can specify the unit of measurement as part of the value. For example, if you want to use GiB, you can specify the unit of measurement like this: maxsize: "400Gi". If not specified, the default value is unlimited.

Resize the PVC by 100% of current size

  actions:
  - name: openstorage.io.action.volume/resize
    params:
      scalepercentage: "100"

This action is to perform expansion on Portworx Storage Pools.

scalepercentage: Specifies the percentage of current Pool size by which Autopilot should resize it. If not specified, the default is 50%.
scaletype: Specifies the type of operation to be performed to expand the pool. Supported values are:
- add-disk: Portworx will add new disk(s) to the existing storage pool
- resize-disk: Portworx will resize existing disks in the storage pool

Expand the pool by 50% of current size by adding disks

  actions:
  - name: openstorage.io.action.storagepool/expand
    params:
      scalepercentage: "50"
      scaletype: "add-disk"
