5GTANGO V&V Curator Module

This is a 5GTANGO component to coordinate the verification and validation activities of 5G Network Services

The Curator acts as the intermediate module between the Planner and the Executor for all V&V tests activities. It is responsible for processing a Test Plan, preparing the SP environment for tests, processing instantiation parameters, triggering the execution and cleaning up the environment afterwards.

Installing / Getting started

Curator should run in coexistence with the rest of components inside the VnV to run properly, however, to execute it as a standalone component for debuging purposes, it can be ran as follows. It is recommended to use a virtual environment for this purpose.

It's important to use tests and network services compatible with each other. Test parameters which are relying on an instantiation, should be addressed in the test descriptor as follows:

$(<function name>/<path>/<object>

Where <function name> is the name of the VNF, <path> is how it is addressed in the instantiation parameters and <object> is the desired record useful for the test.

python -m pip install --upgrade pip setuptools wheel
python setup.py install

To execute it

tng-vnv-curator

It runs the python application, serving at port 6200 by default.

To run it integrated with the rest of SONATA as a docker container:

docker pull registry.sonata-nfv.eu:5000/tng-vnv-curator
docker run -d --name tng-vnv-curator -p 6200:6200 registry.sonata-nfv.eu:5000/tng-vnv-curator

It is recommended to use the quick guide to install the whole V&V platform.

Developing

Built with

Front end is developed in flask under python 3.6, and backend uses requests and docker api.

The whole list of python libraries uses is included in setup.py:

• docker>=3.7.0
• Flask>=1.0.0
• flask-log-request-id
• requests
• six
• urllib3
• psycopg2-binary
• coloredlogs

Prerequisites

It is needed python3.6 It is recommended to have virtualenv installed and setup a workspace separated from the whole system.

Setting up Dev

Setting up a development environment is easy

git clone https://github.com/sonata-nfv/tng-vnv-curator.git
cd tng-vnv-curator/

# Optionally setup a virtual environment
virtualenv -p python3 venv
source venv/bin/activate

python -m pip install --upgrade pip setuptools wheel

Building

To install the module (after seting up dev)

python setup.py develop
