The run.py script in this repository runs within Jenkins any time Jenkins sees a new ceph-ansible Git tag. It creates a new SRPM and builds that in the CentOS Build System (aka Koji, "CBS").

Detailed steps:

• Jenkins listens for new ceph-ansible tags in GitHub. (This is an internal Jenkins system, and the JJB configuration currently lives outside this repository, so just imagine this part).

• Ensure the prerequisites tools are installed on the slave system, eg the "centos-packager" package must be installed.

• make srpm

• Map ceph-ansible versions to CBS build targets. For example, ceph-ansible "v3" should be built in the "mimic" CBS build target (We will need to tweak these mappings over time as upstream ceph-ansible and ceph evolve.)

• Authenticate Jenkins user for CBS.

• cbs build this ceph-ansible .src.rpm file for the appropriate CBS target.

• Tag the build into any additional -candidate tags. For example, new ceph-ansible v3 builds should be immediately tagged into "-luminous-candidate" after they are built in the -mimic build target.

When this is complete, a new ceph-ansible RPM is available in the CBS -candidate tag for the Storage SIG.

Jenkins uses the Credentials Binding plugin to copy a CentOS FAS certificate to the Jenkins slave. The path to the certificate is stored in a CENTOS_CERT environment variable, and this script will symlink ~/.centos.cert to that location.

• Upload source to dist-git

• Figure out what to do for building directly from ceph-ansible master, so TripleO can consume the latest ceph-ansible bits even sooner.

• Expand this for more packages (eg. ceph and nfs-ganesha)
