Multi-Interface for C-VNF
=========================
To use multi-interface for C-VNF, User should follow below procedure.
1. Checking kuryr.conf
~~~~~~~~~~~~~~~~~~~~~~
After installation, user should check kuryr.conf configuration.
.. code-block:: console
$ sudo cat /etc/kuryr/kuryr.conf | grep multi_vif_drivers
multi_vif_drivers = npwg_multiple_interfaces
2. Adding K8s CustomResourceDefinition
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To use CustomResourceDefinition, user needs to add CRD.
User can make a additional network using yaml file like below.
Create yaml file like below and register it.
.. code-block:: console
$ cat ./crdnetwork.yaml
.. code-block:: yaml
apiVersion: apiextensions.k8s.io/v1beta1
kind: CustomResourceDefinition
metadata:
name: network-attachment-definitions.k8s.cni.cncf.io
spec:
group: k8s.cni.cncf.io
version: v1
scope: Namespaced
names:
plural: network-attachment-definitions
singular: network-attachment-definition
kind: NetworkAttachmentDefinition
shortNames:
- net-attach-def
validation:

Register crdnetwork.yaml
.. code-block:: console
$ kubectl create -f ~/crdnetwork.yaml
Get crd list
.. code-block:: console
$ kubectl get crd

3. Adding neutron subnet id information to k8s CRD
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To use neutron subnet in kubernetes, user should register neutron
subnet to CRD. At first, user should create subnet.yaml file.
.. code-block:: console
$ cat ./kuryr-subnetname1.yaml
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
name: subnetname1
annotations:
openstack.org/kuryr-config: '{"subnetId": "$subnet_id"}'
After making a yaml file, user should create subnet with yaml file.
.. code-block:: console
$ kubectl create -f ~/kuryr-subnetname1.yaml
After created, user can check subnet info like below.
.. code-block:: console
$ kubectl get net-attach-def
