From 7e79a933dbe9d22dcfd9069742fcf66923d4a641 Mon Sep 17 00:00:00 2001 From: Michael Johnson Date: Tue, 17 Apr 2018 14:20:41 -0700 Subject: [PATCH] Add pip cache cleanup to pip-and-virtualenv The pip-and-virtualenv element provides pip inside the created images. When this pip is used inside the chroot of the image it, by default, creates a cache directory with the http packages and the resulting wheels. In the case of the octavia ubuntu-minimal image this cache is using ~50MB of cache that is not needed after the image finished building. This package creates a finalise.d task that removes the cache from the default location.
