Garbage Collector

K10 provides a way to collect and clean up the resources that are either orphaned or their expiration period has passed.

The following Helm options can be used to tune Garbage Collector behavior:

  • garbagecollector.daemonPeriod - the length of time between two consecutive garbage collection events (in seconds)

  • garbagecollector.keepMaxActions - how many finished actions to keep (if value is less than or equal to 0, no actions will be deleted)

  • garbagecollector.importRunActions.enabled - enables importRunActions collector (boolean)

  • garbagecollector.retireActions.enabled - enables retireActions collector (boolean)

Supported Resource Types

Garbage Collector daemon can currently clean up the following resource types:

  • RetireActions - when the limit is exceeded, as defined by garbagecollector.keepMaxActions, the oldest retire actions will be removed until the limit is reached.

  • ImportRunActions - when the limit is exceeded, as defined by garbagecollector.keepMaxActions, the oldest import run actions will be removed until the limit is reached.

  • RestorePointContents - expired manual backups will be removed as determined by spec.expiresAt. This can be set via kubectl or on the manual snapshot page in the UI.

  • CSISnapshot - temporary CSI snapshots created during restore operations.

  • PersistentVolumes - temporary volumes created during restore operations.
