# ======================== OpenStack DB Support ================================
|
|
#
|
|
# This section of node attributes stores information about the database hosts
|
|
# used in an OpenStack deployment.
|
|
#
|
|
# There is no 'scheme' key. Instead, there is a 'service_type' key that should
|
|
# contain one of 'sqlite', 'mysql', or 'postgresql'
|
|
#
|
|
# The ::Openstack::db(<SERVICE_NAME>) library routine allows a lookup from any recipe
|
|
# to this array, returning the host information for the server that contains
|
|
# the database for <SERVICE_NAME>, where <SERVICE_NAME> is one of 'compute' (Nova),
|
|
# 'image' (Glance), 'identity' (Keystone), 'network' (Neutron), or 'volume' (Cinder)
|
|
#
|
|
# The ::Openstack::db_connection(<SERVICE_NAME>, <USER>, <PASSWORD>) library routine
|
|
# returns the SQLAlchemy DB URI for <SERVICE_NAME>, with the supplied user and password
|
|
# that a calling service might be using when connecting to the database.
|
|
#
|
|
# For example, let's assume that the database that is used by the OpenStack Identity
|
|
# service (Keystone) is configured as follows:
|
|
#
|
|
# host: 192.168.0.3
|
|
# port: 3306
|
|
# service_type: mysql
|
|
# db_name: keystone
|
|
#
|
|
# Further suppose that a node running the OpenStack Identity API service needs to
|
|
# connect to the above identity database server. It has the following in it's node
|
|
# attributes:
|
|
#
|
|
# node['openstack']['db']['identity']['username'] = 'keystone'
|
|
#
|
|
# In a 'keystone' recipe, you might find the following code:
|
|
#
|
|
# user = node['openstack']['db']['identity']['username']
|
|
# pass = get_password 'db', 'keystone'
|
|
#
|
|
# sql_connection = ::Openstack::db_uri('identity', user, pass)
|
|
#
|
|
# The sql_connection variable would then be set to "mysql://keystone:password@192.168.0.3:keystone"
|
|
# and could then be written to the keystone.conf file in a template.
|
|
#
|
|
# Database Migrations:
|
|
#
|
|
# node['openstack']['db'][<SERVICE_NAME>]['migrate']
|
|
#
|
|
# The above attribute causes database migrations to be executed for the given
|
|
# service. There are cases where migrations should not be executed. For
|
|
# example when upgrading a zone, and the image or identity database are replicated
|
|
# across many zones.
|
|
