<p>Hello,<u></u><u></u></p>
<p><u></u> <u></u></p>
<p>As global requirements changed in Ocata, Kolla upgrads pbr<span style="font-family:Calibri">＞</span>=1.8 [1] , <u></u><u></u></p>
<p>docker-py<span style="font-family:Calibri">＞</span>=1.8.1[2] . Besides, Kolla also starts depending on <u></u><u></u></p>
<p>oslo.utils<span style="font-family:Calibri">＞</span>=3.18.0 to use uuidutils.generate_uuid() instead of uuid.uuid4() to<u></u><u></u></p>
<p>generate UUID.<u></u><u></u></p>
<p><u></u> <u></u></p>
<p>IMHO, Upgrading of [1] and [2] are actually not what Kolla really need to,<u></u><u></u></p>
<p>and uuidutils.generate_uuid() is also supported by oslo.utils-3.16. I mean<u></u><u></u></p>
<p>If we keep Kolla's requirement in Ocata as what it was in Newton, upper layer<u></u><u></u></p>
<p>user of Kolla like daisycloud-core project can still keep other things unchanged <u></u><u></u></p>
<p>to upgrade Kolla from stable/newton to stable/ocata. Otherwise, we have to <u></u><u></u></p>
<p>upgrade from centos-release-openstack-<wbr>newton to <u></u><u></u></p>
<p>centos-release-openstack-<wbr>ocata(we do not use pip since it conflicts with yum <u></u><u></u></p>
<p>on files installed by same packages). But this kind of upgrade may be too <u></u><u></u></p>
<p>invasive that may impacts other applications. <u></u><u></u></p>
<p><u></u> <u></u></p>
<p>I know that there were some discusstions about global requirements update<u></u><u></u></p>
<p>these days. So if not really need to do these upgrades by Kolla itself, can<u></u><u></u></p>
<p>we just keep the requirement unchanged as long as possible?<u></u><u></u></p>
