@ -34,6 +34,23 @@ requests to ``GET /images/<IMAGE_ID>``, the image cache is not automatically
managed. Here, we describe the basics of how to manage the local image cache
on Glance API servers and how to automate this cache management.
Configuration options for the Image Cache
-----------------------------------------
The cache has a number of configuration options that are in the
configuration files.
- ``image_cache_dir`` This is the base directory where Glance stores
the cache data.
- ``image_cache_sqlite_db`` Path to the sqlite file database that will
be used for cache manangement.
- ``image_cache_driver`` The driver used for cache management. (Likely
sqlite.)
- ``image_cache_max_size`` The size when the glance-cache-pruner will
remove the oldest images, to reduce the bytes until under this value.
- ``image_cache_stall_time`` The amount of time an incomplete image will
stay in the cache, after this the incomplete image will be deleted.
