Cloudify clearwater Get Starting Installation
vIMS Clearwater deployment and lifecycle management with Cloudify Orchestrator
Introduction
This repo contains the TOSCA file and the scripts to deploy and manage a MetaSwitch/Clearwater vIMS on OpenStack platform.
It aims to propose a full life-cycle management of this vIMS.
The application description is done with TOSCA description file and the configuration is done with Bash scripts and Python scripts.
To deploy clearwater vIMS many solution already exist like :
- Use Chef with these recipes
- Use Juju with this charms
- Use Docker with these Dockerfiles
- Use OpenStack Heat with these templates
But some of these solutions don't manage full life-cycle management of this application. Life-cycle management this is the deployment of this application but also the monitoring, healing, scaling or again the software upgrade.
The Cloudify ochestrator can manage full application life-cycle. For the moment, only one open-source code exist to deploy Clearwater with Cloudify and Chef. But the best way to benefit fully features from cloudify is to use cloudify not with chef but with python and bash scripts to install and configure the application (VNF).
See Clearwater management part to deploy this vIMS !
Architecture
Clearwater management
Before deploy clearwater, you must have deployed cloudify manager server. To do this, follow this documentation.
Then, you can deploy, monitor, scale and test the clearwater vIMS by following this documentation.
OPNFV
This blueprint is used in OPNFV functest project. The goal of Functest consists in providing comprehensive testing methodology, test suites and test cases to test and verify OPNFV Platform functionality that covers the VIM and NFVI components. See for details on OPNFV/functest ! See for more details about VNF Testing on OPNFV !
In the first release (called Arno), first test suites were focused on the VIM, NFVI and SDN controller through the integration of existing upstream test suites (OpenStack and ODL). The vIMS testcase was also initially planned but finally not integrated. In the second and third release (called Brahmaputra and Collorado), vIMS was integrated as VNF for functional testing.
The goal of this test case consists in deploying and automatically testing a distributed vIMS based on clearwater solution within the OPNFV continuous integration. This test will provide interesting information on the deployment as well as KPI on the functional test suites. In a first step no performance tests are expected but they could be introduced later.
The different step for the continuous Integration can be summarized as follow :
- The preparation of the testing environement including the creation of a dedicated vIMS tenant
- The deployment of the cloudify manager on the target OPNFV platform ;
- The deployment of clearwater vIMS solution with cloudify manager;
- The launch of a function test suite;
- The test, log and monitoring information collection
- The cleaning ot the tenant
