This plugin pre-mounts /var/cache/{yum,dnf} directories inside chroot, so the package manager’s metadata don’t have to be re-downloaded between subsequent mock commands (the caches survive mock --clean for example). This plugin is needed because dnf (or yum) --installroot DIRECTORY commands store caches below the DIRECTORY.

It mounts directories /var/cache/mock/<chroot>/{dnf,yum}_cache as /var/cache/{dnf,yum} in chroot.

You can explicitly clean the package manager caches by --scrub=dnf-cache option.

Configuration

This plugin is enabled by default and has the following values built-in:

config_opts['plugin_conf']['yum_cache_enable'] = True
config_opts['plugin_conf']['yum_cache_opts'] = {}
config_opts['plugin_conf']['yum_cache_opts']['max_age_days'] = 30
config_opts['plugin_conf']['yum_cache_opts']['max_metadata_age_days'] = 30
config_opts['plugin_conf']['yum_cache_opts']['online'] = True

• max_age_days - when files in cache directory is older than this number of days, then such files are removed
• max_metadata_age_days - when metadata (everything with suffix: “.sqlite”, “.xml”, “.bz2”, “.gz”) in cache directory is older than this number of days, then such files are removed.
• online - when False, mock doesn’t apply policies for max_*_age_days options (complements --offline option)
