<p class="MsoNormal">Hi team,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have recently finished the upgrade from ‘docker-py’ to ‘docker’. If your devstack environment run into errors due to the incompatibility between the old and new docker python package (such as [1]), you could try the commands below:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> $ sudo pip uninstall docker-py docker-pycreds<o:p></o:p></p>
<p class="MsoNormal"> $ sudo pip install -c /opt/stack/requirements/upper-constraints.txt \<o:p></o:p></p>
<p class="MsoNormal"> -e /opt/stack/zun<o:p></o:p></p>
<p class="MsoNormal"> $ sudo systemctl restart devstack@kuryr*<o:p></o:p></p>
<p class="MsoNormal"> $ sudo systemctl restart devstack@zun*<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For context, ‘docker-py’ is the old python-binding library for consuming docker REST API. It has been renamed to ‘docker’ and the old package will be dropped eventually. At the last a few days, there are several reports of errors due to
double installation of both ‘docker-py’ and ‘docker’ packages in the development environment, so we need to migrate from ‘docker-py’ to ‘docker’ to resolve the issue.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Right now, all Zun’s components and dependencies has finished the upgrade [2][3][4], and there is another proposed patch to drop ‘docker-py’ from global requirements [5]. The package conflict issue will be entirely resolved when the upgrade
is finished globally.<o:p></o:p></p>
