Kuryr - Container networking¶
“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. Kuryr requires at least Keystone and neutron. Kolla makes kuryr deployment faster and accessible.
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
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
By default etcd and kuryr are disabled in the
In order to enable them, you need to edit the file globals.yml and set the
enable_etcd: "yes" enable_kuryr: "yes"
Deploy the OpenStack cloud and kuryr network plugin
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
