ManageIQ OpenStack Infrastructure Provider

The OpenStack infrastructure provider is designed to work with a TripleO-based OpenStack deployment. It provides visibility and management capabilities for the undercloud.

Features

• Scaling of the overcloud through ManageIQ
  • Function enabled through both the UI and Automate
• Host data collection
  • Base attributes through OpenStack APIs (Ironic, Heat, Tuskar)
  • Metrics through OpenStack Ceilometer
  • OpenStack component views, detailing the status and configuration of installed OpenStack services, through host fleecing
• Image data collection through the OpenStack Glance API

In Development

• Exposing additional management capabilities provided by OpenStack APIs

Installation

Install a TripleO-based OpenStack deployment

The recommended way to do this can be found here: https://www.rdoproject.org/tripleo/

Afterwards, you’ll need to expose the undercloud’s API endpoints: https://wiki.openstack.org/wiki/Tuskar/Instack#Connecting_to_Undercloud_from_external_place_.28e.g._your_laptop.29

Enable Events in the Undercloud

To enable events in the undercloud, update the following configuration files on the undercloud node:

• /etc/heat/heat.conf
  • notification_driver=messaging
  • notification_topics=notifications
• /etc/nova/nova.conf
  • notification_driver = messaging
  • notification_topics = notifications

Then, restart all Heat and Nova services.

Add the TripleO-based OpenStack deployment (undercloud) to ManageIQ

Follow these steps to add a TripleO-based OpenStack deployment (undercloud) to ManageIQ

• Go to Infrastructure -> Providers
• Under ‘Configuration’ select ‘Add a New Infrastructure Provider’
• In the resulting form, choose ‘OpenStack Infrastructure’ as the Type and fill in the ‘Basic Information’ and ‘Credentials’ form
  • Note that the IP Address must match the IP shown when running ‘keystone endpoint-list’ in the undercloud

Enable Host Fleecing (Optional)

Follow these steps to enable host fleecing. Note that the OpenStack infrastructure provider will still work if these steps are not run; there will simply be less information available through the ManageIQ UI.

• Enable the SmartProxy role:
  • Go to Configure -> Configuration
  • Select SmartProxy in Server Roles, Server Control section
  • Click Save
• Add configuration files to default host profile:
  • Go to Configure -> Configuration
  • Click on host default in Analysis profiles on the left side bar
  • Add configuration files that you want to analyze:
    • ex: /etc/*/*.conf, /etc/*/*.ini
• Enable host fleecing with the heat-admin user:
  • Go to undercloud node
  • Get the private key from /home/stack/.ssh/id_rsa
  • In the ‘RSA KEY pair tab’ of Infra provider add heat-admin User ID and the private file from step 2
• Enable host fleecing with the root user:
  • Go to undercloud node
  • Get the private key from /home/stack/.ssh/id_rsa
  • Switch to the stack user
    • su - stack
  • Get the IP addresses of overcloud nodes
    • . stackrc
    • nova list
  • Connect to each overcloud nodes by using heat-admin user
    • ex: ssh heat-admin@192.0.2.8
  • Switch to root user
    • sudo -i
  • Edit .ssh/authorized_keys to allow regular login
    • sed -i ‘s/no-port-forwarding.*10” //’ .ssh/authorized_keys
  • In the ‘RSA KEY pair tab’ of Infra provider add root User ID and the private file from step 2

Add Alert and Event for Auto-Acaling through Automate (Optional)

To enable auto-scaling, follow the instructions in the ManageIQ depot.
