Overview

Class: nova::compute::image_cache

Configures image caching in nova

Parameters:

manager_interval

(optional) Number of seconds to wait between runs of the image cache manager. Defaults to $::os_service_default

subdirectory_name

(optional) Location of cached images. Defaults to $::os_service_default

remove_unused_base_images

(optional) Should unused base images be removed? Defaults to $::os_service_default

remove_unused_original_minimum_age_seconds

(optional) Unused unresized base images younger than this will not be removed. Defaults to $::os_service_default

remove_unused_resized_minimum_age_seconds

(optional) Unused resized base images younger than this will not be removed. Defaults to $::os_service_default

precache_concurrency

(optional) Maximum number of compute hosts to trigger image precaching in parallel. Defaults to $::os_service_default

Parameters:

  • manager_interval (Any) (defaults to: $::os_service_default)
  • subdirectory_name (Any) (defaults to: $::os_service_default)
  • remove_unused_base_images (Any) (defaults to: $::os_service_default)
