We would like to announce that OKD v3.11 rpms been officially released and are available at http://mirror.centos.org/centos/7/paas/x86_64/openshift-origin311/. 
OKD is the Origin community distribution of Kubernetes.
In order to use the released repo  we have created and published the rpm (contains the yum configuration file)  which is in the main CentOS extra repository. The rpm itself has a dependency on the centos-release-ansible26  which is the ansbile 2.6 version rpm built by CentOS Infra team.
Should you decide not to use the centos-release-openshift-origin3* rpm then will be your responsibility to get ansible 2.6 required to by openshift-ansible installer.
Please note that due to ongoing work on releasing CentOS 7.6, the mirror.centos.org repo is in freeze mode - see https://lists.centos.org/pipermail/centos-devel/2018-November/017033.html  and as such we have not published the rpms to http://mirror.centos.org/centos/7/paas/x86_64/openshift-origin/ . Once the freeze mode will end, we'll publish the rpms.
Kudos goes to CentOS Infra team for being very kind in giving us a waiver to make the current release possible.
