Azure Redis Cache Plugin

Overview

The Azure Redis Cache Plugin integrates RightScale Self-Service with the basic functionality of the Azure Redis Cache service.

Requirements

• A general understanding CAT development and definitions
  • Refer to the guide documentation for details SS Guides
• The admin, ss_designer & ss_end_user roles, in a RightScale account with SelfService enabled. admin is needed to retrieved the RightScale Credential values identified below.
• Azure Service Principal (AKA Azure Active Directory Application) with the appropriate permissions to manage resources in the target subscription
• The following RightScale Credentials
  • AZURE_APPLICATION_ID
  • AZURE_APPLICATION_KEY
• The following packages are also required (See the Installation section for details):
  • sys_log

Installation

1. Be sure your RightScale account has Self-Service enabled
2. Connect AzureRM Cloud credentials to your RightScale account (if not already completed)
3. Follow steps to Create an Azure Active Directory Application
4. Grant the Azure AD Application access to the necessary subscription(s)
5. Retrieve the Application ID & Authentication Key
6. Create RightScale Credentials with values that match the Application ID (Credential name: AZURE_APPLICATION_ID) & Authentication Key (Credential name: AZURE_APPLICATION_KEY)
7. Retrieve your Tenant ID
8. Update azure_mysql_plugin.rb Plugin with your Tenant ID.
   • Replace "TENANT_ID" in token_url "https://login.microsoftonline.com/TENANT_ID/oauth2/token" with your Tenant ID
9. Navigate to the appropriate Self-Service portal
   • For more details on using the portal review the SS User Interface Guide
10. In the Design section, use the Upload CAT interface to complete the following:
    1. Upload each of packages listed in the Requirements Section
    2. Upload the azure_mysql_plugin.rb file located in this repository

How to Use

The Azure Redis Cache Plugin has been packaged as plugins/rs_azure_redis. In order to use this plugin you must import this plugin into a CAT.

import "plugins/rs_azure_redis"

For more information on using packages, please refer to the RightScale online documentation. Importing a Package

Azure Redis Cache resources can now be created by specifying a resource declaration with the desired fields. See the Supported Actions section for a full list of supported actions. The resulting resource can be manipulated just like the native RightScale resources in RCL and CAT. See the Examples Section for more examples and complete CAT's.

Supported Resources

• cache
• firewall_rule
• patch_schedule

Examples

Please review redis_test_cat.rb for a basic example implementation.
