<div dir="ltr"><div>OK, so the bottleneck is in "INSTALL / TEST (IMPORT IMAGES)" stage with 2 Triple-O scenario, 3 Packstack and 3 OpenStack-Puppet test jobs.

<br>
First, the job "rdo-promote-get-hash-master" will run. If it is<br>
successful, it triggers the next "stage" of the pipeline.<br>
Then, the job "tripleo-quickstart-promote-<wbr>master-delorean-build-images"<br>
will run. If it is successfull, it triggers the next "stage" of the<br>
pipeline.<br>
After that you have 8 jobs that, if capacity allows (usually the<br>
case), will all run simultaneously. Otherwise, builds can be queued<br>
until a slave can process them.<br>
... and so on.<br>
<br>
We can't realistically run all these jobs in a sequence.<br>
Considering they complete in 45 minutes (or more), we'd be looking at<br>
a pipeline of over 6 hours of builds.<br>
