OAI VNF Packages and Image Generator scripts

This repo contains:

• VNF Packages
• Scripts for generating the disk image (LXD/KVM)

NFV

These are the files to create the VNF Packages.
To create the tar files:

cd nfv
make

The tar files can then be uploaded into Open Baton.

NOTE: The OAI SPGW requires kernel modifications and therefore cannot be run in a container, instead it must be run in a KVM.

Image Generation

KVM

Use diskimage-builder to create a qcow2 image. You will need access to a linux box (can be a kvm or virtual box).

Download and install diskimage-builder

cd /tmp
wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

sudo pip install --upgrade pip dib-utils networkx

sudo apt install -y curl kpartx python-yaml qemu-utils kpartx
cd ~/
git clone http://git.openstack.org/openstack/diskimage-builder.git

Upgrade setuptools to the latest version: (from setuptools-18.3.3 to setuptools-36.2.2 for example – python ./setup.py install may fail with the older version of setuptools)

sudo pip install -U pip setuptools

cd diskimage-builder
sudo python ./setup.py install

sudo pip install -r requirements.txt

Download the diskimage-builder element files for OAI SPGW

cd ~/
git clone https://github.com/RuthDevlaeminck/OAI_VNF.git

Tell the diskimage-builder where the elements are

export ELEMENTS_PATH=~/OAI_VNF/images/oai_kvm_files/dib_elements

Build the image

disk-image-create -o OpenAirInterfaceEPC -t qcow2 -a amd64 -x ubuntu vm OpenAirInterfaceEPC

Upload the image to openstack (use cli)

glance image-create --name oai-image-kvm --visibility private --container-format bare --disk-format qcow2 --file OpenAirInterfaceEPC.qcow2 --progress

LXD

Use custom built image generator located at https://github.com/corenetdynamics/image-generator.git

Create the tar file containing the OAI specific files

cd ~/OAI_VNF/images/oai_lxc_files
./compress.sh

Edit the image.yaml file to point at the generated tar file
