[kolla][zun] Zun image source

Hi Kolla team, I was looking into the CentOS Zun image downloaded from DockerHub. It looks the source code is from stable/train branch: $ docker run kolla/centos-source-zun-compute:master cat zun/zun.egg-info/pbr.json {"git_version": "25e56636", "is_release": false} The git_version points to the stable/train branch, but I think it should point to the master branch. FWIW, I also checked the Ubuntu image and the git version in there looks correct: $ docker run kolla/ubuntu-source-zun-compute:master cat zun/zun.egg-info/pbr.json {"git_version": "6fbf52ae", "is_release": false} Any suggestion? Best regards, Hongbin
