Kuryr in Kolla

"Kuryr is a Docker network plugin that uses Neutron to provide networking services to Docker containers. It provides containerized images for the common Neutron plugins" [1]. Kuryr requires at least Keystone and neutron. Kolla makes kuryr deployment faster and accessible.

Requirements

  • A minimum of 3 hosts for a vanilla deploy

Preparation and Deployment

To allow Docker daemon connect to the etcd, add the following in the docker.service file.

ExecStart= -H tcp://172.16.1.13:2375 -H unix:///var/run/docker.sock --cluster-store=etcd://172.16.1.13:2379 --cluster-advertise=172.16.1.13:2375

The IP address is host running the etcd service. `2375 is port that allows Docker daemon to be accessed remotely. 2379` is the etcd listening port.

By default etcd and kuryr are disabled in the group_vars/all.yml. In order to enable them, you need to edit the file globals.yml and set the following variables

enable_etcd: "yes"
enable_kuryr: "yes"

Deploy the OpenStack cloud and kuryr network plugin

kolla-ansible deploy

Create a Virtual Network

docker network create -d kuryr --ipam-driver=kuryr --subnet=10.1.0.0/24 --gateway=10.1.0.1 docker-net1

To list the created network:

docker network ls

The created network is also available from OpenStack CLI:

openstack network list
