## DLRN

DLRN is a Continuous Delivery platform that take every upstream commit and build it as a
consumable package for CI purpose.

```bash

## DLRN CI

* master: every commit or almost is built
* consistent: set of packages without build failures
* current-passed-ci: snapshot that passed CI
* stable releases: packages from upstream tagged tarballs + sanity checks

* RDO CI targets consistent snapshots
* Upstream CI projects targets current-passed-ci (e.g. packstack, tripleO, kolla, puppet)
