<div style="font-size: 14px; font-family: Calibri, sans-serif;">You have to extend the kolla_docker module. An example is here:</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;"><a href="https://github.com/openstack/kolla/blob/master/ansible/library/kolla_docker.py#L597">https://github.com/openstack/kolla/blob/master/ansible/library/kolla_docker.py#L597</a></div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;"><br>
</div>
<div>Search the file for the word host – you will probably need stuff wherever that is except with pid duplicated with ipc. I recommend a patch prior to your current patch to introduce the feature to kolla_docker.</div>
