openSUSE - the most tested linux distribution

Transcript

1. Martin Pluskal Maintenance QA martin@pluskal.org openSUSE the most tested linux distribution
2. openSUSE project • Community project sponsored by SUSE • Its aim being usage of opensource and free technologies • Responsible for (among others) openSUSE distribution • Founded on August 9 2005
3. SUSE • Company founded in Germany (1992) • Linux distributions (SLES, SLED a derivatives) • SUSE Cloud (OpenStack + HPE Hellion) • SUSE Enterprise Storage (Ceph) • CaaSP/Kubic (Kubernetes) • OBS a more
4. Why openSUSE • Simple installation and configuration • Support from community and SUSE people • Community and conferences
5. Which openSUSE? Tumbleweed
6. Leap • Versions 15.0 and 15.1, 15.2 in development • Derived from SLE(S|D) • SLE-15-SP0 matches 15.0 • SLE-15-SP1 matches 15.1
7. Leap • Core of system (kernel, glibc etc) same as in SLES • Leap users will get same updates as SLE customers • Rest (ie graphical environment) is inherited from Tumbleweed • “Hybrid distribution” • Supports x86_64 a unoficially arm6/7 and aarch64
8. Tumbleweed • Rolling release distribution • Released as snapshots (usually multiple per week) • Supports x86_64, i586, unofficial support for arm6/7 aarch64 ppc/ppc64/ppc64le and s390x
9. Linux distribution • Compilation of thousands of packages • Have to be usable together • 30000 Debian • 49000 openSUSE • 47000 arch (including aur repository)
10. Classic releases • Stable release every couple of months/years • Same package version during whole life or release • Fixes are backported
11. What is rolling release? • Allways updated (and tested) • There is no stable release • Only release that is stable is the last snapshot • No roadmap of releases • Updates/new stuff is released when it passes QA (if there is QA)
12. Why rolling release? • Software projects are developed at faster pace than most regular distributions • Linux kernel (3 months) • GNOME (6 months) • KDE Plasma (3 months) • Docker (3 months) • SaltStack (3-6 months)
13. Why rolling release • Maintaining old versions of SW is diffucult/time consuming/costly • Users want new functionality • Support for latest hardware
14. Common issues/concerns • Its not really stable/its broken • Its not really usable in real life • Behavior changes too often
15. Stability/functionality/QA ? • How to make sure that it all works together? • Testing by users/community? • Specialised/professionall testers? • Automation?
16. Testing • Does the component work as expected? • Does the whole system behave as expected after the component got updated? • Is there a change in behavior from point of view of users?
17. OBS and openQA • OBS = Open Build Service • openQA = openQA
18. OBS • Building packages (not just openSUSE/rpm) • Can create iso image, qcow2, oci • Used by Dell, Intel, Cray, ownCloud, vlc, Linux Foundation and more https://openqa.opensuse.org/
19. openQA • Testing simulates user sitting in front of computer • Focused on scenarios – from installation to shutdown • Not only graphical testing • Multi machine jobs https://open.qa
20. Staging • Staging projects for Factory • Integration tests • Multiple reviews
