What do you think? > I think you may want to change ovirt-appliance to build from ovirt-release-master-tested instead of from ovirt-release-master. This way appliance is going to consume the repos as fresh as they passes OST chain. I think you may also want to trigger appliance build 4 times a day (it takes a couple of hours for a build so probably no big advantage doing it more often. The appliance is going to be sent to tested repo right after build. OST image should then get it from master-tested repo instead of master-nightly. This way you should get OST images updated 4 times a day. > > Thanks and best regards, > > [1] https://jenkins.ovirt.org/job/ovirt_master_publish-rpms_nightly/ > [2] > https://jenkins.ovirt.org/job/ovirt-appliance_master_build-artifacts-el8-x86_64/ > [3] > https://jenkins.ovirt.org/job/ost-images_master_standard-poll-upstream-sources/ > [4] > https://jenkins.ovirt.org/job/ovirt-system-tests_he-basic-suite-master/ > -- > Didi > _______________________________________________ > Devel mailing list -- [email protected] > To unsubscribe send an email to [email protected] > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/[email protected]/message/EY4V5JLE7MWN5L3NZMHYTJ2B3W3HAGEV/ > -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> [email protected] <https://www.redhat.com/> *Red Hat respects your work life balance.
