1. Daisy4nfv: An Installer Based upon Open Source Project – Daisy & Kolla
Basic Architecture and Brief Background
contacts:

2. Daisy4nfv Project Description
An installer project based upon upstream installer -Daisy(
Daisy4nfv works as an installer for each OPNFV release. It will support deployment of OPNFV full stack, with different flavors of configuration.

3. Daisy4nfv Project Description
The unique values that Daisy4nfv will bring to the OPNFV community
Daisy provides facilitated features such as configuration template, auto deployment, multicast imaging, etc. which can improve the efficiency and quality of deployment for large data center.
Containerizing OpenStack services by introducing Kolla( to achieve fast deploying and atomic upgrading.
Abstracts and provides necessary information and API for escalator to perform upgrading efficiently and accordingly.

4. Project Scope
Absorbing OPNFV's release cadence features through the genesis project.
Working closely with genesis and escalator project together to provide a improved solution for both installation and upgrading.
Providing needed capabilities for the OPNFV CI pipeline, including:
Build
Deployment
Integration with test projects
Needed hooks for low-level verification (Functest)
Needed hooks for high-level verification (Scenario testing) – Yardstick
Integration with SDN controllers such as ONOS, ODL etc

5. Testability
Local lab resources are used for integration and testing for upstream Daisy project.
Collaborate with related OPNFV project (releng/functest) to provide testability for all Daisy4nfv based artifacts.

6. Dependencies Depends on open source upstream projects

Kolla(

11. The following slides previously were used for reviewing on TC meeting.

12. What is Daisy Installer for distributed systems
Deployment and management of OpenStack and other distributed systems.
An OpenStack-related project ( ).
Previously mainly developed by ZTE.

13. Daisy Highlights
Daisy’s highlights concentrates on the deployment of large data centers
Containerized OpenStack Services
Multicast
Automatic Deployment
Configuration Template

14. Daisy Highlights Containerized OpenStack Services
Use Kolla as underlying deployment module Fast deploying and atomic upgrading
Kolla is not a installer. Needs Installer such as Daisy to do node discovery and OS provisioning before hand.

16. Daisy Highlights Automatic Deployment

Auto assign role and start deploymemt for a new discovered node.
Currently only support automatic deployment for computer node in one cluster.

17. Daisy Highlights Configuration Template
Using precise configuration file to describe a big dynamic cluster is not applicable.
Precise configuration file is not able to be reused when moving to another approximate environment.
Configuration template only describes the common part of the cluster and the representative of the controller/compute nodes.
During deployment, users only have to evaluate few specific parameters to make the configuration template a final configuration file.

Using precise configuration file to describe a big dynamic cluster is not applicable, and it is not able to be reused when moving to another approximate environment either. Daisy’s configuration template only describes the common part of the cluster and the representative of the controller/compute nodes. It can be seen as a semi-finished configuration file which can be used in any approximate environments. During deployment, users only have to evaluate few specific parameters to make the configuration template a final configuration file.

Resp.
“Daisy API
extention” is a plug-in of Daisy, and it will be used as a bridge between installer and upgrader. Data changed in Daisy which related to upgrading will be passed based upon a publication to it. Later, upgrader can query such information from Information Provider.
Further, by generalizing “What to provide” and “How to provide”(API) to a more common layer, such as genesis, a loose coupling design of installer and upgrader can be achieved.
Yellow: to be implemented as part of Daisy4nfv Proposal
Blue: existing upstream installer -“Daisy”
Green: existing component in OPNFV project

20. What Daisy4nfv will do to extend Daisy+Kolla
Building artifact:
Extends Kolla to build OPNFV containers(such as ODL container, etc.).
Packaging containers’ images into Daisy artifact.
Functions provided by the artifact:
Extends Daisy Dashboad to let user to specify OPNFV scenarios.
Extends Daisy to generate Kolla config file for deploying OPNFV containers according to specified scenarios.
Extends Kolla to deploy OPNFV containers.
Extends Daisy API to provide information about component version etc. to other projects .
