The main objective is to use Neutron as a networking backend option for Docker. The original proposal was to do so in the context of using containers (for different Neutron backends or vif types).

It is as you say, the goal of Kuryr to provide Docker with a new libnetwork remote<br>driver that is powered by Neutron, not a containerization of Neutron. Kuryr deployments as you point out,<br>may opt to point to a Neutron that is containerized, and for that I was looking at using Kolla. However,<br>that is just deployment and I consider it to be something up to the deployer (of course, we'll make Kuryr<br></div><div>containerizable and part of Kolla :-) ).<br></div><div><br>The design for interaction/configuration is not yet final, as I still have to push drafts for the blueprints and<br>get comments, but my initial idea is that you will configure docker to pass the configuration of which<br>device to take hold of for the overlay and where the neutron api are in the following way.<br><br><pre><code>$ docker -d --kv-store=consul:localhost:8500 --label=com.docker.network.driver.kuryr.bind_interface=eth0 </code><code>--label=com.docker.network.driver.kuryr.neutron_api=10.10.10.10 </code><br><code><code>--label=com.docker.network.driver.kuryr.token=</code></code><code><code></code><code>AUTH_tk713d067336d21348bcea1ab220965485</code><br><br></code></pre><pre><code><span style="font-family:arial,helvetica,sans-serif">Another possibility is that those values were passed as env variables or plain old configuration files.</span><br></code></pre> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><p><br>Now, there is another aspect of using containers in the context of this project that is more interesting at least to me (and I do not know if others share this view or not) and that is the use of containers for providing network services that are not available through libnetwork as of now or in near future or ever. From the talks I have had with libnetwork developers the plan is to stay with the basic networking infrastructure and leave additional features to be developed by the community and to do so possibly by using what else, containers. <br></p></div></blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><p><br>So take the current features available in libnetwork. You mainly get support for connectivity/isolation for multiple networks across multiple hosts. Now if you want to route between these networks, you have to devise a solution yourself. One possible solution would be having a router service in a container that gets connected to say two Docker networks. Whether the router service is implemented with the use of the current Neutron router services or by some other solutions is something to look into and discuss but this is a direction where I think Kuryr (did I spell it right? ;)) can and should contribute to.<br></p></div></blockquote><div><br></div><div>You got that right. The idea is indeed to get the containers networked via libnetwork that, as you point out,<br>was left intentionally simple to be developed by the community; then we want to make make:<br><br></div><div>a) Kuryr get the containers to networks that have been pre-configured with advanced networking (lb, sec groups, etc).<br>Being able to perform changes on those networks via neutron after the fact as well. For example the container<br>orchestration software could create a Neutron network with a load balancer and a FIP, start containers on that network<br>and add them to the load balancer.<br>b) Via the usage of either docker labels on `docker run` make Kuryr implicitly set up Neutron networks/topologies.<br><br></div><div>Yup, you spelled it well.
