Public bug reported:
The GlanceMirror class has a hard-coded filter for items to be downloaded. Anyone using it directly or via the script in tools/sstream-mirror-glance to load images into an openstack cloud will end up with a large number of images, at least one for each of the available release series, and only x86_64 or amd64. It is likely that users will want to be able to limit the images they download to just one release, and may want to be able to download images for other architectures, such as arm*. The uploaded package simply exposes the existing filter mechanism as a config option, using the previous hardcoded values as defaults. This config option is used (currently it is just ignored by the published simplestreams code) in an charm that is released on the charm store for trusty, 'glance-simplestreams-sync'. Users of OpenStack on Trusty are likely to want the option to control image downloads via that charm. [Test Case] In an openstack cloud, with proper openstack env vars (OS_USERNAME, OS_PASSWORD, OS_REGION etc), run the sstream-mirror-glance tool to download images locally: from the source tree top directory, PYTHONPATH=. tools/sstream-mirror-glance --max=1 -v -v -v --output-dir \ images/ --cloud-name test_cloud --content-id test_content \ --keyring /usr/share/keyrings/ubuntu-cloudimage-keyring.gpg \ http://cloud-images.ubuntu.com/releases/ streams/v1/index.json verify that it downloads many images. This may take a while. If you like, you can just check that it will download an image for an old series like raring or quantal. Clean up after it by removing the images/ directory. Then with the update applied, from the source tree top dir: PYTHONPATH=. tools/sstream-mirror-glance --max=1 -v -v -v --output-dir \ images/ --cloud-name test_cloud --content-id test_content \ --keyring /usr/share/keyrings/ubuntu-cloudimage-keyring.gpg \ --item-filter="release=trusty" --item-filter="arch=arm64" \ http://cloud-images.ubuntu.com/releases/ streams/v1/index.json and verify that it downloads only one matching image, trusty on arm64. [Regression Potential] This has very limited regression potential, because anyone relying on the existing behavior will still get it because the previous behavior is retained via defaults. ** Affects: simplestreams Importance: Undecided Status: Fix Committed ** Affects: simplestreams (Ubuntu) Importance: High Status: Confirmed ** Tags: cloud-installer ** Also affects: simplestreams Importance: Undecided Status: New ** Changed in: simplestreams Status: New => Fix Committed ** Branch linked: lp:~mikemc/simplestreams/add-filters-glance -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to simplestreams in Ubuntu. https://bugs.launchpad.net/bugs/1339842 Title: GlanceMirror item filters are hardcoded To manage notifications about this bug go to: https://bugs.launchpad.net/simplestreams/+bug/1339842/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
