[ovs-discuss] status of ovn-docker

[Gal Sagie]

Hi Mark,

If you are deploying this with OpenStack, it will be nice for you to be
familiar with project Kuryr.
I have written an introduction blog post about the project here:
http://galsagie.github.io/sdn/openstack/docker/kuryr/neutron/2015/08/24/kuryr-part1/

And an Integration of Kuryr and OVN blog post here:
http://galsagie.github.io/sdn/openstack/docker/kuryr/neutron/2015/10/10/kuryr-ovn/

In short Kuryr maps Docker APIs to Neutron API so you can use any Neutron
plugin for implementing
containers networking. (and OVN/OVS included)
We also plan to support special use cases for nested containers in VM (that
can expose OVN
feature of defining parent and child logical ports for this same use case)

We are now working as well on modifying all the changes needed due to
Docker 1.9 API changes.

Let me know if you have any questions.

Thanks
Gal.
