This cookbook provides common setup recipes, helper methods and attributes that describe an OpenStack deployment as part of the OpenStack reference deployment Chef for OpenStack.
- Chef 0.10.0 or higher required (for Chef environment use).
The following cookbooks are dependencies:
- apt
- database
- yum
- yum-epel
Please see the extensive inline documentation in attributes/*.rb
for descriptions
of all the settable attributes for this cookbook.
Note that all attributes are in the default["openstack"]
"namespace"
openstack['api']['auth']['version']
- Select v2.0 or v3.0. Default v2.0. The default auth API version used by other components to interact with identity service.
Support multiple network types. Default network type is "nova" with the other option supported being "neutron".
The attribute is in the default["openstack"]["compute"]["network"]["service_type"]
.

Iterates over the contents of the node['openstack']['endpoints']
hash and
finds any occurrence of bind_interface
to set the IP address
(node['openstack']['endpoints']['identity']['bind_interface'] = 'eth0'
for
example, overriding node['openstack']['endpoints']['identity']['host']
). If
bind_interface
isn't set, the value of host
is not modified.
"run_list": [
"recipe[openstack-common::set_endpoints_by_interface]"
]
Creates an /root/openrc file. This requires the identity attributes for admin_user and admin_tenant_name, or for the identity_service_chef_role to be used on the identity server node.
Iterates over the contents of the node['openstack']['sysctl']
hash and writes
the entries to /etc/sysctl.d/60-openstack.conf
.

This cookbook containes Libraries to work with passwords and secrets in databags. Databags can be unencrypted ( for dev ) or encrypted ( for prod ). In addition to traditionally encrypted data bags they can also be created as chef-vault items. To read more about chef-vault and how to use it, go to https://docs.getchef.com/chef_vault.html.
Documentation for Attributes for selecting databag format can be found in the attributes section of this cookbook.
Documentation for format of these Databags can be found in the Openstack Chef Repo repository.
This cookbook exposes a set of default library routines:
cli
-- Used to call openstack CLIsendpoint
-- Used to return a::URI
object representing the named OpenStack endpointendpoints
-- Useful for operating on all OpenStack endpointsdb
-- Returns a Hash of information about a named OpenStack databasedb_uri
-- Returns the SQLAlchemy RFC-1738 DB URI (see: http://rfc.net/rfc1738.html) for a named OpenStack databasedb_create_with_user
-- Creates a database and database user for a named OpenStack databasesecret
-- Returns the value of an encrypted data bag for a named OpenStack secret key and key-sectionget_password
-- Ease-of-use helper that returns the decrypted password for a named database, service or keystone user.
The following are code examples showing the above library routines in action.
Remember when using the library routines exposed by this library to include
the Openstack routines in your recipe's ::Chef::Recipe
namespace, like so:
class ::Chef::Recipe
include ::Openstack
end
Example of using the endpoint
routine:
nova_api_ep = endpoint "compute-api"
::Chef::Log.info("Using Openstack Compute API endpoint at #{nova_api_ep.to_s}")
# Note that endpoint URIs may contain variable interpolation markers such
# as `%(tenant_id)s`, so you may need to decode them. Do so like this:
require "uri"
puts ::URI.decode nova_api_ap.to_s
Example of using the get_password
and db_uri
routine:
db_pass = get_password "db" "cinder"
db_user = node["cinder"]["db"]["user"]
sql_connection = db_uri "volume", db_user, db_pass
template "/etc/cinder/cinder.conf" do
source "cinder.conf.erb"
owner node["cinder"]["user"]
group node["cinder"]["group"]
mode 00644
variables(
"sql_connection" => sql_connection
)
end
Use the Openstack::uri_from_hash
routine to helpfully return a ::URI::Generic
object for a hash that contains any of the following keys:
host
uri
port
path
scheme
If the uri
key is in the hash, that will be used as the URI, otherwise the URI will be
constructed from the various parts of the hash corresponding to the keys above.
# Suppose node hash contains the following subhash in the :identity_service key:
# {
# :host => 'identity.example.com',
# :port => 5000,
# :scheme => 'https'
# }
uri = ::Openstack::uri_from_hash(node[:identity_service])
# uri.to_s would == "https://identity.example.com:5000"
The routine will return nil if neither a uri
or host
key exists in the supplied hash.
Don't like prefixing calls to the library's routines with ::Openstack
? Do this:
class ::Chef::Recipe
include ::Openstack
end
in your recipe.
Please refer to the TESTING.md for instructions for testing the cookbook.
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.
