tng-sdk-package

This repository contains the tng-sdk-package component that is part of the European H2020 project 5GTANGO NFV SDK. This component is responsible to create and unpack 5GTANGO service, VNF, and test packages. The seed code of this component is based on the son-cli toolbox that was developed as part of the European H2020 project SONATA.

To simplify the creation and extraction of 5GTANGO packages, we develop this packager tool as part of 5GTANGO's SDK. This tool is a complete rewrite of the SONATA packaging tool. The reason for this rewrite is that the 5GANGO packaging tool does not only support and simplifies the package creation but can also be used to unpack packages. For this, the packaging tool can be deployed as a micro service and used, e.g., by the service platform to unpack packages. The clear benefit of this design, compared to the SONATA design in which we used different tools for this, is that only one common codebase needs to be maintained that deals with packages. Thus, code changes, which may be a result of a change in the package format, need only be done in a single component of 5GTANGO. The architecture and design of the packaging tools is described in 5GTANGO D4.1 First open-source release of the SDK toolset in more detail.

Documentation

• 5GTANGO D4.1 First open-source release of the SDK toolset

Installation and Dependencies

This component is implemented in Python3. Its requirements are specified here.

Automated:

The automated installation requires pip (more specifically pip3).

# install official release from PyPi
$ pip install tngsdk.package

# install latest version from GitHub master
$ pip install git+https://github.com/sonata-nfv/tng-sdk-package

Manual:

$ git clone git@github.com:sonata-nfv/tng-sdk-package.git
$ cd tng-sdk-package
$ python setup.py install

Hint:

It is a good practice to first create a new virtual environment in which all 5GTANGO SDK tools can be installed. You can do this as follows:

# get the path to your Python3 installation
which python3

# create a new virtualenv
virtualenv -p <path/to/python3> venv

# activate the virtualenv
source venv/bin/activate

Usage

The packager can either be used as command line tool (CLI mode) or deployed as a micro service which offers a REST API.

CLI mode

Runs the packager locally from the command line. Details about all possible parameters can be shown using:

tng-pkg -h

Packaging

# package a 5GTANGO SDK project
tng-pkg -p misc/5gtango_ns_project_example1

Unpackaging

# unpack a 5GTANGO package to a local 5GTANGO SDK project
tng-pkg -u misc/5gtango-ns-package-example.tgo

Service mode

Runs the packager as a micro service that exposes a REST API.

• Note: Currently only unpackaging is supported in this mode.

Run tng-sdk-package as a service:

Bare metal

tng-pkg -s

Docker-based

# build Docker container
pipeline/build/build.sh

# run Docker container
docker run --rm -d -p 5099:5099 --name tng-sdk-package registry.sonata-nfv.eu:5000/tng-sdk-package

Unpackaging

# terminal 1 (run tng-sdk-package service)
tng-pkg -s

# terminal 2 (client that sends a package to be unpacked using REST API)
curl -X POST -v -H "Content-Type: multipart/form-data" \
    -F package="@misc/5gtango-ns-package-example.tgo" \
    http://127.0.0.1:5099/api/v1/packages
    
# get status of all known packageing processes
curl -X GET http://127.0.0.1:5099/api/v1/packages/status

Development

To contribute to the development of this 5GTANGO component, you may use the very same development workflow as for any other 5GTANGO Github project. That is, you have to fork the repository and create pull requests.

Setup development environment

$ python setup.py develop

CI Integration

All pull requests are automatically tested by Jenkins and will only be accepted if no test is broken.

Run tests manually

You can also run the test manually on your local machine. To do so, you need to do:

$ pytest -v

Execute full CI pipeline locally:

$ ./pipeline_local.sh
