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.
