Policy Guided Fulfillment Demo

This topic provides information on demo of Policy Guided Fulfillment .

Demo Scenario

• The cloud admin(s) sets 2 policy rules:
  • Tenant A can only use MySQL as a DB vendor
  • Tenant B can only use PostgreSQL as a DB vendor
• The admin wishes to model a Tomcat application that depends on a DB
  • Tenant A admin models it with a MySQL DB
  • Tenant B admin models it with a PostgreSQL DB
• Application developer want to add a workflow to the application deployment that will verify the Tomcat is up and running (by sending a GET request) and will send an email notifying whether the deployment has completed successfully or not.
• The admins deploy the application models to Murano. The package will also include the Mistral workflow (so we will not depend on it being pre-deployed to Mistral)
• End user of tenant A wishes to deploy the Tomcat application that relies on PostgreSQL
  • Deployment fails since the policy rules restrict this DB for tenant A
• End user of tenant A asks Murano to deploy tomcat with MySQL DB
  • Application is deployed
  • At the end of deployment phase, the workflow is deployed to Mistral (programmatically, by this specific application deployment logic)
  • The workflow is triggered by the application class
  • A mail will be sent to the end user indicating whether Tomcat has been deployed and whether it is responsive

Demo Setup Guide

Prerequisities

• OpenStack
  • enabled services Murano, Mistral, and Congress
  • configured networking
• VM images
  • Ubuntu based image
  • Centos (RedHat) based image
  • Each image
    • installed Murano Agent
    • if you are behind proxy, then image has to have proxy support enabled
• Networking
  • Access to internet is required
    • if you have proxy access to internet, you have to configured it in our lab, and VM images
