Abstract

This document describes the stoney cloud (OpenStack) relevant OpenLDAP directory data organisation.

Introduction

This document describes the OpenLDAP directory data organisation for the stoney cloud service.

Data Organisation

The following chapters explain the data organisation of the stoney cloud OpenLDAP directory, in this case we looking at the stoney cloud service.

IaaS (Infrastructure as a Service)

The subtree ou=openstack,ou=service,dc=stoney-cloud,dc=org contains all the OpenStack based stoney cloud service data. The following LDIF shows the iaas entry for the stoney cloud service: 

dn: ou=openstack,ou=services,dc=stoney-cloud,dc=org
objectclass: top
objectclass: organizationalUnit
ou: openstack

Configuration

dn: ou=configuration,ou=openstack,ou=services,dc=stoney-cloud,dc=org 
objectclass: top
objectclass: organizationalUnit
ou: configuration
description: The sub tree for the configuration of the OpenStack based stoney cloud service.

Configuration (resellers)

dn: ou=reseller,ou=configuration,ou=openstack,ou=services,dc=stoney-cloud,dc=org
objectclass: top
objectclass: organizationalUnit
ou: reseller

Domains (resellers)

dn: ou=domains,ou=openstack,ou=services,dc=stoney-cloud,dc=org 
objectclass: top
objectclass: organizationalUnit
ou: domains
description: The sub tree for the domains (resellers) of the OpenStack based stoney cloud service.

Domain (OpenStack Default Domain) example

This is a very special domain and is created during the bootstrapping phase of the OpenStack installation. Therefore we never provision this domain and we don't add the objectclass: sstProvisioning to this domain. 

dn: uid=3999998,ou=domains,ou=openstack,ou=services,dc=stoney-cloud,dc=org
objectclass: top
objectclass: sstOpenStackDomain
objectclass: sstRelationship
uid: 3999999
sstOpenStackId: default
sstOpenStackName: Default
description: The default domain
sstIsActive: TRUE
sstBillable: FALSE
sstBelongsToResellerUID: 4000000

Domain (OpenStack Service Provider Domain) example

This is also quite a special domain, as it collects the cloud administrators of the OpenStack based stoney cloud. It is added manually just after the bootstrapping phase. Therefore we never provision this domain and we do not add the objectclass: sstProvisioning to this domain. 

dn: uid=3999999,ou=domains,ou=openstack,ou=services,dc=stoney-cloud,dc=org
objectclass: top
objectclass: sstOpenStackDomain
objectclass: sstRelationship
uid: 3999999
sstOpenStackId: abcdef2477be64c099500224864999998
sstOpenStackName: Service Provider
description: Service Provider stepping stone GmbH
sstIsActive: TRUE
sstBillable: FALSE
sstBelongsToResellerUID: 4000000

Domain (reseller) example

dn: uid=4000000,ou=domains,ou=openstack,ou=services,dc=stoney-cloud,dc=org
objectclass: top
objectclass: sstOpenStackDomain
objectclass: sstProvisioning
objectclass: sstRelationship
uid: 4000000
sstOpenStackId: b01822477be64c09950022486300c59c
sstOpenStackName: Reseller Ltd.
description: 4000000 - Reseller Ltd.
sstIsActive: TRUE
sstBillable: TRUE
sstProvisioningMode: added
sstProvisioningExecutionDate: 0
sstProvisioningState: 20180819T083208Z
sstBelongsToResellerUID: 4000000
sstBelongsToCustomerUID: 4000001

Notes

  • sstBillable: FALSE If the attribute doesn't exist, it will take the value from the reseller ou=billing sub tree.
  • sstBelongsToCustomerUID: 4000001 Not necessary.
  • sstBelongsToPersonUID: 4000002 Not necessary.
  • Use date --utc "+%Y%m%dT%H%M%SZ" to set the attribute sstProvisioningState manually.
  • The uid normally has the same value as the sstBelongsToResellerUID attribute.

The following table describes the different attributes:

Attribute
Existence
Mandatory
 Description
uid
MUST
x
 A unique integer value with 7 digits or more. In the case of OpenStack Domains (resellers), the value of uid corresponds with the value of sstBelongsToResellerUID. For example: uid: 4000000 corresponds with sstBelongsToResellerUID: 4000000.
sstOpenStackId
MAY<center>
<center>x The OpenStack Domain id as returned from the OpenStack API. For example: "id" : "b01822477be64c09950022486300c59c". This gives us the LDAP entry: sstOpenStackId: b01822477be64c09950022486300c59c.
sstOpenStackName
MAY
x
 The OpenStack Domain name as returned from the OpenStack API. For example: "name" : "Reseller Ltd.",. This gives us the LDAP entry: sstOpenStackName: Reseller Ltd..
description
MAY
x
 The description is built up as follows: <sstBelongsToResellerUID> - <sstOpenStackName>. For example: description: 4000000 - Reseller Ltd..
sstIsActive
MUST
x
 Is the entry active? Either TRUE (yes) or FALSE (no). The default value is TRUE.
sstBillable
MAY
x
 It the entry billable? Either TRUE (yes) or FALSE (no). All hierarchical levels must have sstBillable: TRUE to actually have an invoice generated and sent. If the attribute sstBillable doesn't exist, the default is TRUE. This way, we are forced to set a reseller, customer or product manually to sstBillable: FALSE if we want to avoid sending them an invoice.
sstProvisioningMode
MUST
x
 The provisioning mode, either add, modify or delete. For a new account, this attribute must be set to add. See the stoney core: OpenLDAP provisioning page for details. If the entry was successfully added, modified or deleted, the provisioning mode is changed to added, modified or deleted.
sstProvisioningExecutionDate
MUST
x
 The date the provisioning shall occur in the form of [YYYY][MM][DD] (ISO 8601). For a new account, this attribute must be set to 0. See the stoney core: OpenLDAP provisioning page for details.
sstProvisioningState
MUST
x
 The provisioning state, either 0 or in the form of [YYYY][MM][DD]T[hh][mm][ss]Z (ISO 8601). Z is the zone designator for the zero UTC offset. For a new OpenStack Domain, this attribute must be set to 0. After the successful provisioning, the value is set to the time of the provisioning. For example: sstProvisioningState: 20180819T083208Z. See the stoney core: OpenLDAP provisioning page for details.
sstBelongsToResellerUID
MAY
x
 Stores the reseller UID the leaf belongs to. A unique value with 7 digits or more. For example: 4000000.

A unique integer value with 7 digits or more. In the case of OpenStack Domains (resellers), the value of sstBelongsToResellerUID corresponds with the value of uid . For example: sstBelongsToResellerUID: 4000000 corresponds with uid: 4000000.

sstBelongsToCustomerUID
MAY
x
 Stores the customer UID the leaf belongs to. A unique value with 7 digits or more, must correspond with the uid entry. This value is required, as the all products must belong to a customer. For example: sstBelongsToCustomerUID: 4000001.

Legend:

  • x: Mandatory in all cases.
  • x1: If sstIsCompany is set to TRUE, the organizationName must be set. Otherwise givenName and surname must be set.

Project (tenant) examples

Due to the OpenStack project (tenant) organisation, we can have multiple tenants per domain (reseller) and customers. The following LDIF example show the first project of the customer Customer Ltd. with the sstBelongsToCustomerUID: 4000001 belonging to the reseller Reseller Ltd. with the sstBelongsToResellerUID: 4000000:

sstBelongsToServiceUID <- What value? Will this cause a ldap search over all the services?

Questions

  • We need a mechanism to make sure, that the internal OpenStack domain(s) and the corresponding project(s) don't get provisioned!
  • Should we have a configuraton sub tree with sane default values?
  • Should we store the current values in the LDAP (CPU, RAM, ...)?
  • Will we store the network configuraton in the LDAP?
    • If yes, how will we store the additional networks in the LDAP (shared network)?
  • How will we make sure, not to bill the IPv4 netwoks, belonging to a reseller and/or customer?
    • For example Fence IT AG?
  • Will we have both sstBelongsToDomainID and sstBelongsToDomainUID or just one or the other?
