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,
