features:
|
|
- Pass proxy information from agent driver to IPA ramdisk, so that images
|
|
can be cached on the proxy server.
|
|
issues:
|
|
- When using caching proxy with ``agent_*`` drivers, caching the image on the
|
|
proxy server might involve increasing [glance]swift_temp_url_duration
|
|
config option value. This way, the cached entry will be valid for a period
|
|
of time long enough to see the benefits of caching. Large temporary URL
|
|
duration might become a security issue in some cases.
|
|
upgrade:
|
|
- Adds a [glance]swift_temp_url_cache_enabled configuration option to enable
|
|
Swift temporary URL caching. It is only useful if the caching proxy is
|
|
used. Also adds [glance]swift_temp_url_expected_download_start_delay, which
|
|
is used to check if the Swift temporary URL duration is long enough to let
|
|
the image download to start, and, if temporary URL caching is enabled, to
|
|
determine if a cached entry will be still valid when download starts. The
|
|
value of [glance]swift_temp_url_expected_download_start_delay must be less
|
|
than the value for the [glance]swift_temp_url_duration configuration
|
|
option.
