These are personal notes I used to install OSP (mostly versions 10 and OSP) many times along this year.
Please note I never wrote above notes for a wide audience. There could be something wrong on above document as in the last two months there could have been some changes in TripleO or Infrared that brokes it. I know what you are speaking about as I borrowed this document by reverse ingegnering a Jenkins CI job and putting toghether with info I received during my training.
I hope this could help somebody as it did for me.
Best regards
Federico Ressi
