<p>Then IMO, the global requirements process seems against the intention of requirement.txt file. Since requirement.txt is per-project, not global. It is (just for example) Zun that treat docker-py-1.8 as a must. As for Kolla, both 1.6 and 1.8 are OK. Then
there is no need to force Kolla to change its requirement from "docker-py <span style="font-family:Calibri">
＞</span>=1.6.0" to "docker-py <span style="font-family:Calibri">＞</span>=1.8.0" by the global requirements process, otherwise, user may think Kolla really need a newer version, kind of easy to be misread.<o:p></o:p></p>
<p><o:p> </o:p></p>
<p>We know it is valuable to upgrade requirements globally, as it is condusive to early bug detection of the co-installation circumstance. But can we not to do that detection in each project's CI by write it literally in each project's requirement.txt but just
upgrade required packages globally in a dedicated CI that tests the projects which really need to be co-installed? <o:p></o:p></p>

<p class="MsoNormal">Zun required docker-py to be 1.8 or higher because older version of docker-py didn't have the API we need. Sorry if it caused difficulties on your side but I don't think it is feasible to downgrade the version for now since it will affect
a ton of other projects.<o:p></o:p></p>

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