<p class="MsoNormal"><span style="font-family:"Helvetica",sans-serif;color:black">Hi All,<br>
<br>
It is very sad to hear nova-docker's retirement. Me and my team (3) are<br>
working for a cloud computing laboratory and we were very keen on<br>
working with nova-docker.<br>
After some research about its current state I saw these mails. Will you<br>
actually propose another equivalent to nova-docker or is it just the<br>
lack of contributors to this project?<br>
Some of the contributors previously advised us the magnum project<br>
instead of nova-docker, however it does not satisfy our needs because of<br>
the additional virtualization layer it needs.<br>
If the main problem is the lack of contributors we may participate in<br>
this project.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Helvetica",sans-serif;color:black">There's never any need to ask permission to contribute to a project :) If nova-docker driver is something you cannot do without, feel free to contribute to it.<br>
<br>
That said, Magnum does seem to be where most of the docker-related contributions to the compute landscape have moved. So, it's more likely you will find company in that project and perhaps be able to make more effective contributions there. Can I ask what is
the "extra virtualization layer" that you are referring to in Magnum?<br>
