Nested virtualization in centos-ci?
by Honza Horak 17 Feb '16

17 Feb '16

Hi, I'm wondering if something like nested virtualization is possible/available/recommended in centos ci. My use case is that we would like to have a test for mariadb galera and this test is hard to be written on one machine + ideally we'd like to test real machine to machine workflow. Is it something we can do in the jenkins? Honza

Internal mirror for content you (ab)use within the CI env (aka adding cloud.centos.org)
by Fabian Arrotin 17 Feb '16

17 Feb '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In the last days, I had to grow the number of nodes behind cloud.centos.org in the centos.org infra, and when I added two more nodes, I saw that there were requests coming from the CI env to those cloud.centos.org nodes : "GET │ │/centos/7/devel/CentOS-7-x86_64-GenericCloud-GA-7.0.1406_01.qcow2 HTTP/1.1" 200 343368704 "-" "ansible-httpget" So, to speed up all those requests, I've created yesterday an internal mirror for cloud.centos.org, so that such requests will not go "outside" and use Internet bandwidth. If you have a need for an internal mirror for content you have to download for each of your tests, feel free to ask on this list, and we'll add it. That will mean faster download speed for your test[s] (internal to the DC) and also more internet bandwidth available for other tasks in that DC (so win/win) Kind Regards, - -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iEYEARECAAYFAlbEGKAACgkQnVkHo1a+xU7AjQCdG/7pEM3GuUv5YOKFqmujRIkH 8I8AoIxdkbljxdFjG+eRXdIkHFLEXkWI =Uz+G -----END PGP SIGNATURE-----

Need few packages to be installed in centos jenkins slave
by Vishwanath Bhat 16 Feb '16

16 Feb '16

Hi, I am trying to run gluster tests from the Jenkins slave setup provided by centos infra. So in our case Jenkins slave also acts as a management node for the test framework. That node orchestrates the tests in each of the test machines. So in order to run the tests from the framework, I need few packages to be present in the slave machine and have passwordless ssh setup between the jenkins slave to all test machines. The second part it already taken care by the infra. We just need few packages to be installed on the slave. The slave is "slave01.ci.centos.org". And the packages required are plumbum, rpyc and unittest-xml-reporting. Since all of the above are python modules, I probably can use virtualenv and run the tests. I am going to try that tomorrow and update here. But in the meantime, if someone has access can install those packages, it would be of great help. Best Regards, Vishwanath

Add more executors for atomicapp-shared
by Dusty Mabe 16 Feb '16

16 Feb '16

Right now I can only execute two tests at a time. Would be nice to be able to do more tests at a time but if this is expensive it might not be worth it since we don't constantly run tests. Is it possible to add more executors for atomicapp-shared ? - Dusty

CI job Trigger and Feedback for Github
by Praveen Kumar 16 Feb '16

16 Feb '16

Hi, So currently we have provision to add our Github project to CentOS CI but it lack on feedback[0] like travis do. I searched available plugin to do that for Jenkins and looks like github[1] is promising. Can we enable it to CI or we have other plan to resolve it?

Emergency Maintenance Period: 11-Feb-2016 01:00 UTC (10-Feb-2016 20:00 Eastern)
by Brian Stinson 11 Feb '16

11 Feb '16

Hi Folks, We need to do an emergency maintenance period in CI overnight tonight to reconfigure some of the duffy database parameters. We will pause new jobs in Jenkins 1 hour beforehand and re-queue them after we are finished. Services affected: - Duffy API We expect this outage to be very short while we restart the database. I'll send updates here to the list, and hang out in #centos-devel during that time. Cheers! -- Brian Stinson CentOS CI Infrastructure Team

Mirror images on artifacts.ci.centos.org
by John Trowbridge 02 Feb '16

02 Feb '16

Hello, I brought this up on IRC before the holidays, but it was suggested to bring it to this list. We have some images that get created during CI of RDO-Manager[1], and a project that lets people consume these images to get a fully operational deathst^w TripleO cloud using them.[2] I have had reports from users though that the download speed outside of the Red Hat RDU VPN is quite bad. Do we have anywhere we can mirror these images? [1] https://ci.centos.org/artifacts/rdo/images/ [2] https://github.com/redhat-openstack/tripleo-quickstart

Disk space on ci nodes
by Dusty Mabe 30 Jan '16

30 Jan '16

Hi, Is it possible to get raw block device storage on nodes in the CI? Right now from what I can tell the nodes come up with LVM set up and no space free in the volume group. There is a root/home/swap LV and we can't really reclaim any space because xfs doesn't support shrinking the FS. Can we have some free space left in the VG? Is there some other way to get this to happen? Thanks, Dusty

How do you transform the config.xml into a job builder yaml file?
by James 27 Jan '16

27 Jan '16

Has anyone done the work of automating the translation, or does anyone have a script? Here's a script to download the config.xml: https://github.com/purpleidea/oh-my-vagrant/blob/master/extras/get-xml-jenk… If someone has the translate part that would be pretty useful. Cheers, James

Reaping at 12 hrs instead of 2 days
by Karanbir Singh 22 Jan '16

22 Jan '16

hi, In the coming days, we are going to start moving towards reaping orphaned machines every 12 hrs. At the moment, machines are reclaimed on the second date change ( ie. if you provisioned at 00:01 on anyday, you get 48 hrs before the machine is reclaimed, or if you provisioned at 23:59, you get 24 hrs ). Going forward, this will reduce to 12 hrs. Looking through the last month worth of reclaimed nodes, it looks like the longest running roles typically finish in under 2 hrs or thereabouts - so 12 hrs should still be plenty of head room. Machines that dont usually returned within 3 hrs + are the ones we almost exclusively end up reclaiming on the timeout. Therefore, this 12 hr timeout should not impact anyone / any jobs. Let me know if thats not the case. Regards -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc
