kuryr-libnetwork
Docker for OpenStack Neutron
Kuryr-libnetwork is Kuryr's Docker libnetwork driver that uses Neutron to provide networking services. It provides containerised images for the common Neutron plugins.
This repo provides libnetwork specific functionalities such as handler methods for libnetwork apis. All the logic/utilities that can be shared among different container networking frameworks such as Docker's libnetwork, K8s's CNI and so on, is maintained in separate Kuryr repo as a common library.

Features

Prerequisites
$ sudo pip install -r requirements.txt
Installing Kuryr's libnetwork driver
Running the following will grab the requirements and install kuryr:
$ sudo pip install .
Configuring Kuryr
Generate sample config, etc/kuryr.conf.sample, running the following:
$ tox -e genconfig
Rename and copy config file at required path:
$ cp etc/kuryr.conf.sample /etc/kuryr/kuryr.conf
Edit keystone section in /etc/kuryr/kuryr.conf, replace ADMIN_PASSWORD:
auth_uri = http://127.0.0.1:35357/v2.0
admin_user = admin
admin_tenant_name = service
admin_password = ADMIN_PASSWORD
In the same file uncomment the bindir parameter with the path for the Kuryr vif binding executables:
bindir = /usr/local/libexec/kuryr
Running Kuryr
Currently, Kuryr utilizes a bash script to start the service. Make sure that you have installed tox before the execution of the command below:
$ sudo ./scripts/run_kuryr.sh
After Kuryr starts, please restart your Docker service, e.g.:
$ sudo service docker restart
The bash script creates the following file if it is missing:
/usr/lib/docker/plugins/kuryr/kuryr.json
: Json spec file for libnetwork.
Note the root privilege is required for creating and deleting the veth pairs with pyroute2 to run.
Testing Kuryr
For a quick check that Kuryr is working, create a network:
$ docker network create --driver kuryr test_net
785f8c1b5ae480c4ebcb54c1c48ab875754e4680d915b270279e4f6a1aa52283
$ docker network ls
NETWORK ID NAME DRIVER
785f8c1b5ae4 test_net kuryr
To test it with tox:
$ tox
You can also run specific test cases using the -e
flag,
e.g., to only run the fullstack test case:
$ tox -e fullstack
Generating Documentation
We use Sphinx to maintain the documentation. You can install Sphinx using pip:
$ pip install -U Sphinx
In addition to Sphinx you will also need the following requirements (not covered by requirements.txt):
$ pip install oslosphinx reno 'reno[sphinx]'
The source code of the documentation are under doc, you can generate the html files using the following command. If the generation succeeds,a build/html dir will be created under doc:
$ cd doc
$ make html
Now you can serve the documentation at http://localhost:8080 as a simple website:
$ cd build/html
$ python -m SimpleHTTPServer 8080
Limitations
To create Docker networks with subnets having same/overlapping cidr, it is expected to pass unique pool name for each such network creation Docker command. Docker cli options -o and --ipam-opt should be used to pass pool names as shown below:
$ sudo docker network create --driver=kuryr --ipam-driver=kuryr \
--subnet 10.0.0.0/16 --ip-range 10.0.0.0/24 \
-o neutron.pool.name=neutron_pool1 \
--ipam-opt=neutron.pool.name=neutron_pool1 \
foo
eddb51ebca09339cb17aaec05e48ffe60659ced6f3fc41b020b0eb506d364
Now Docker user creates another network with same cidr as the previous one, i.e 10.0.0.0/16, but with different pool name, neutron_pool2:
$ sudo docker network create --driver=kuryr --ipam-driver=kuryr \
--subnet 10.0.0.0/16 --ip-range 10.0.0.0/24 \
-o neutron.pool.name=neutron_pool2 \
--ipam-opt=neutron.pool.name=neutron_pool2 \
