The Python version of the Open Baton vnfm-sdk
Python version of the vnfm-sdk
This project contains a vnfm sdk for python projects.
This section covers the requirements that must be met by the python-vnfm-sdk in order to satisfy the demands for such a component:
- python 2.7 or 3.5
How to install python-vfnm-sdk
The safer way to start is to use a virtal environment. Once activated, just run
pip install python-vnfm-sdk
How to configure your vnfm
The sdk runs a certain number of instances of the vnfm by invoking the method:
def start_vnfm_instances(vnfm_klass, config_file_path, instances=1, **kwargs): # .... pass
where the parameters are the Vnfm class that implements AbstractVnfm, the config file path for the vnfm, the number of instances and the instantiation arguments for the vnfm class.
The ini config file looks like
[vnfm] endpoint_type=RABBIT type=python endpoint=python-endpoint log_path=/var/log/openbaton/ broker_ip=127.0.0.1 autodelete=true heartbeat=60 exchange=openbaton-exchange
|type||The type of the vnfm|
|endpoint_type||must be RABBIT|
|broker_ip||Ip of the rabbitmq broker used by the nfvo|
|username||username for the rabbitmq broker used to connect to the manager queue of the nfvo|
|password||password for the rabbitmq broker used to connect to the manager queue of the nfvo|
|exchange||exchange name used in the rabbitmq broker by the nfvo|
|autodelete||true or false in case you want the endpoint queue to have the autodelete property (usually true)|
|heartbeat||heartbeat for the rabbitmq connection|
|log_path||path where the logfile will be written|
see the python dummy vnfm as example
Issues and bug reports should be posted to the GitHub Issue Tracker of this project
What is Open Baton?
OpenBaton is an open source project providing a comprehensive implementation of the ETSI Management and Orchestration (MANO) specification.
Open Baton is a ETSI NFV MANO compliant framework. Open Baton was part of the OpenSDNCore (www.opensdncore.org) project started almost three years ago by Fraunhofer FOKUS with the objective of providing a compliant implementation of the ETSI NFV specification.
Open Baton is easily extensible. It integrates with OpenStack, and provides a plugin mechanism for supporting additional VIM types. It supports Network Service management either using a generic VNFM or interoperating with VNF-specific VNFM. It uses different mechanisms (REST or PUB/SUB) for interoperating with the VNFMs. It integrates with additional components for the runtime management of a Network Service. For instance, it provides autoscaling and fault management based on monitoring information coming from the the monitoring system available at the NFVI level.
