Hi Jay, I was asking because our discussions to contribute to nova-docker project ran across the discussions here to retire the project :) 

Hongbin, that is exactly what I meant. Using nova-docker it deploys containers to physical machines, not virtual machines. 
Using Ironic driver with Magnum is a solution, but I guess every time creating a cluster with Magnum it will redeploy the operating system for the selected physical machine, which is not necessary. 
I will investigate Zun project more, thank you very much. What would you say for its current maturity level?

Konu: Re: [openstack-dev] [nova][nova-docker] Time to retire nova-docker? 

I guess "extra virtualization layer" means Magnum provisions a Container Orchestration Engines (COE) on top of nova instances. If the nova instances are virtual machines, there is a "extra virtualization layer". 

I think you could consider using Magnum with Ironic driver. If the driver is Ironic, COEs are deployed to nova instances that are physical machines provided by Ironic. Zun project [1] could be another option for your use case. Zun is similar to nova-docker, which enables running containers on compute hosts. You could find a thoughtful introduction here [2].

Hi All, 

It is very sad to hear nova-docker's retirement. Me and my team (3) are 
working for a cloud computing laboratory and we were very keen on 
working with nova-docker. 
After some research about its current state I saw these mails. Will you 
actually propose another equivalent to nova-docker or is it just the 
lack of contributors to this project? 
Some of the contributors previously advised us the magnum project 
instead of nova-docker, however it does not satisfy our needs because of 
the additional virtualization layer it needs. 
If the main problem is the lack of contributors we may participate in 
this project. 


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. 

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? 

Best, 
-jay
