Ok perfect, I’ll have a look at the whole process and try to cleanup all my note and make a clear documentation of them.
For the image I just choose to goes the CICD way with DIB and successfully get a centos working image. I’m now facing a SSL handshake issue, but I’ll try to fix it as I suspect my certificates to be incorrect and then create a new discussion feed if I don’t found out what’s going on. Thanks a lot for your help and kuddos to the Octavia team that build a rock solid solution and provide an awesome work. I especially love the healthManager/Housekeeper duo as I wished for nova and other OS Services to get some (Tempest I’m looking at you) in order to make my life easier by properly managing resources waist.
