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
