Chris Dearborn 0db09aba5d Add ability to specify IP for service 
The problem that this change addresses is that the address_for method
will not work correctly if there are multiple IP address associated
with the specified interface.

The approach to solving this problem and moving towards the overall
goal of having one place where service networking information is
stored is to convert address_for calls into endpoints, and add a
address() method to the endpoints interface for IP address resolution.

The address() method has the following behavior: if the
bind_interface of an endpoint is set, then the IP is looked up on
the interface.  Otherwise, the IP specified in the host attribute is
returned.  This allows the caller to choose either method of
determining what IP a service will be bound to.

This initial change switches both the openstack-ops-database and
openstack-ops-messaging cookbooks over to use endpoints instead of
address_for.  The other cookbooks will be switched over time.

README.md

Description

This cookbook provides shared message queue configuration for the OpenStack Havana reference deployment provided by Chef for OpenStack. The http://github.com/mattray/chef-openstack-repo contains documentation for using this cookbook in the context of a full OpenStack deployment. It currently supports RabbitMQ and will soon other queues.

Requirements

Chef 11 with Ruby 1.9.x required.

Platforms

  • Ubuntu-12.04

Cookbooks

The following cookbooks are dependencies:

  • openstack-common
  • rabbitmq

Usage

The usage of this cookbook is optional, you may choose to set up your own messaging service without using this cookbook. If you choose to do so, you will need to provide all of the attributes listed under the Attributes.

Resources/Providers

None

Templates

None

Recipes

server

  • message queue server configuration, selected by attributes

rabbitmq-server

  • configures the RabbitMQ server for OpenStack

Attributes

  • openstack["mq"]["cluster"] - whether or not to cluster rabbit, defaults to 'false'

The following attributes are defined in attributes/messaging.rb of the common cookbook, but are documented here due to their relevance:

  • openstack["endpoints"]["mq"]["host"] - The IP address to bind the rabbit service to
  • openstack["endpoints"]["mq"]["scheme"] - Unused at this time
  • openstack["endpoints"]["mq"]["port"] - The port to bind the rabbit service to
  • openstack["endpoints"]["mq"]["path"] - Unused at this time
  • openstack["endpoints"]["mq"]["bind_interface"] - The interface name to bind the rabbit service to

If the value of the "bind_interface" attribute is non-nil, then the rabbit service will be bound to the first IP address on that interface. If the value of the "bind_interface" attribute is nil, then the rabbit service will be bound to the IP address specified in the host attribute.

Testing

Please refer to the TESTING.md for instructions for testing the cookbook.

Berkshelf

Berks will resolve version requirements and dependencies on first run and store these in Berksfile.lock. If new cookbooks become available you can run berks update to update the references in Berksfile.lock. Berksfile.lock will be included in stable branches to provide a known good set of dependencies. Berksfile.lock will not be included in development branches to encourage development against the latest cookbooks.
