READ THIS

This cookbook is used to track the upstream cookbook at stackforge/cookbook-openstack-identity (which it is a fork of). We need to port everything to ruby-1.8.7 for SUSE Cloud. The intent is to constantly rebase the few fix-commits on top of new upstream changes.

Please don't push any functional changes to this cookbook and also beware that this repository's git history WILL be overwritten.

Description

This cookbook installs the OpenStack Identity Service Keystone as part of the OpenStack reference deployment Chef for OpenStack. The https://github.com/stackforge/openstack-chef-repo contains documentation for using this cookbook in the context of a full OpenStack deployment. Keystone is installed from packages, creating the default user, tenant, and roles. It also registers the identity service and identity endpoint.

http://keystone.openstack.org/

Requirements

Chef 0.10.0 or higher required (for Chef environment use)

Cookbooks

The following cookbooks are dependencies:

Attributes

Please refer to the Common cookbook for more attributes.

• openstack['identity']['db_server_chef_role'] - The name of the Chef role that knows about the db server
• openstack['identity']['user'] - User keystone runs as
• openstack['identity']['group'] - Group keystone runs as
• openstack['identity']['db'] - Name of keystone database
• openstack['identity']['db_user'] - Username for keystone database access
• openstack['identity']['db_passwd'] - Password for keystone database access
• openstack['identity']['db_ipaddress'] - IP address of the keystone database
• openstack['identity']['api_ipaddress'] - IP address for the keystone API to bind to. TODO: Rename to bind_address
• openstack['identity']['verbose'] - Enables/disables verbose output for keystone API server
• openstack['identity']['debug'] - Enables/disables debug output for keystone API server
• openstack['identity']['admin_token'] - Admin token for bootstraping keystone server
• openstack['identity']['roles'] - Array of roles to create in the keystone server
• openstack['identity']['users'] - Array of users to create in the keystone server
• openstack['identity']['pastefile_url'] - Specify the URL for a keystone-paste.ini file that will override the default packaged file
• openstack['identity']['token']['expiration'] - Token validity time in seconds
• openstack['identity']['catalog']['backend'] - Storage mechanism for the keystone service catalog
• openstack['identity']["control_exchange"] - The AMQP exchange to connect to if using RabbitMQ or Qpid, defaults to openstack
• openstack['identity']['rpc_backend'] - The messaging module to use
• openstack['identity']['rpc_thread_pool_size'] - Size of RPC thread pool
• openstack['identity']['rpc_conn_pool_size'] - Size of RPC connection pool
• openstack['identity']['rpc_response_timeout'] - Seconds to wait for a response from call or multicall
• openstack['identity']['ldap']['url'] - LDAP host URL (default: 'ldap://localhost')
• openstack['identity']['ldap']['user'] - LDAP bind DN (default: 'dc=Manager,dc=example,dc=com')
• openstack['identity']['ldap']['password'] - LDAP bind password (default: nil)
• openstack['identity']['ldap']['use_tls'] - Use TLS for LDAP (default: false)
• openstack['identity']['ldap']['tls_cacertfile'] - Path to CA cert file (default: nil)
• openstack['identity']['ldap']['tls_cacertdir'] - Path to CA cert directory (default: nil)
• openstack['identity']['ldap']['tls_req_cert'] - CA cert check ('demand', 'allow' or 'never', default: 'demand')
• openstack['identity']['misc_keystone'] - Array of strings to be added to keystone.conf

Most openstack['identity']['ldap'] attributes map directly to the corresponding config options in keystone.conf's [ldap] backend. They are primarily used when configuring openstack['identity']['identity']['backend'] and/or openstack["identity"]["assignment"]["backend"] as ldap (both default to sql).

The openstack['identity']['ldap']['use_tls'] option should not be used in conjunction with an ldaps:// url. When the latter is used (and openstack['identity']['ldap']['use_tls'] = false), the certificate path and validation will instead be subject to the OS's LDAP config.

If openstack['identity']['ldap']['tls_cacertfile'] is set, openstack['identity']['ldap']['tls_cacertdir'] will be ignored. Set openstack['identity']['ldap']['tls_cacertfile'] to nil if openstack['identity']['ldap']['tls_cacertdir'] is desired. Values of openstack['identity']['ldap']['tls_req_cert'] correspond to the standard options permitted by the TLS_REQCERT TLS option (never performs no validation of certs, allow performs some basic name checks but no thorough CA validation, demand requires the certificate chain to be valid for the connection to succeed).

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

• openstack['endpoints']['identity-bind']['host'] - The IP address to bind the identity services to
• openstack['endpoints']['identity-bind']['scheme'] - Unused
• openstack['endpoints']['identity-bind']['port'] - Unused
• openstack['endpoints']['identity-bind']['path'] - Unused
• openstack['endpoints']['identity-bind']['bind_interface'] - The interface name to bind the identity services to

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

Token flushing

When managing tokens with an SQL backend the token database may grow unboundedly as new tokens are issued and expired tokens are not disposed of. Expired tokens may need to be kept around in order to allow for auditability.

It is up to deployers to define when their tokens can be safely deleted. Keystone provides a tool to purge expired tokens, and the server recipe can create a cronjob to run that tool. By default the cronjob will be configured to run hourly.

The flush tokens cronjob configuration parameters are listed below:

• openstack['identity']['token_flush_cron']['enabled'] - Boolean indicating whether the flush tokens cronjob is enabled. It is by default enabled if the token backend is 'sql'.
• openstack['identity']['token_flush_cron']['log_file'] - The log file for the flush tokens tool.
• openstack['identity']['token_flush_cron']['hour'] - The hour at which the flush tokens cronjob should run (values 0 - 23).
• openstack['identity']['token_flush_cron']['minute'] - The minute at which the flush tokens cronjob should run (values 0 - 59).
• openstack']['identity']['token_flush_cron']['day'] - The day of the month when the flush tokens cronjob should run (values 1 - 31).
• openstack['identity']['token_flush_cron']['weekday'] = The day of the week at which the flush tokens cronjob should run (values 0 - 6, where Sunday is 0).

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.
