(c) ruan.he@orange.com & thomas.duval@orange.com -============ Introduction ============ -This guide presents the use of the MoonClient script. -The MoonClient script allows the administrator/user to drive the Moon platform and some parts of the Keystone server itself. - -============= -Pre-requisite -============= - -Before using the MoonClient script, you must export some variables in your shell. -Those variables are the same as the variables used to execute the OpenStack client or the Nova/Swift/Neutron/... clients. -You can export directly in the shell like this: - -.. code-block:: bash - - export OS_USERNAME=admin - export OS_PASSWORD=password - export OS_REGION_NAME=What_ever_you_want - export OS_TENANT_NAME=admin - export OS_AUTH_URL=http://localhost:5000/v2.0 - -Or you can source a shell script: - -.. code-block:: bash - - cat << EOF | tee ~/set_openstack_auth.sh - #!/usr/bin/env bash - export OS_USERNAME=admin - export OS_PASSWORD=password - export OS_REGION_NAME=What_ever_you_want - export OS_TENANT_NAME=admin - export OS_AUTH_URL=http://localhost:5000/v2.0 - EOF - source ~/set_openstack_auth.sh - -It is important to notice that those variables are **exactly** the same you use for the OpenStack clients. - -===== -Usage -===== - -The main usage of the MoonClient is: - -.. code-block:: bash - - $ moon --help - usage: moon [--version] [-v | -q] [--log-file LOG_FILE] [-h] [--debug] - [--username ] [--tenant ] - [--password ] [--authurl ] - command - ... - -MoonClient ca be used interactively: - -.. code-block:: bash - - $ moon - -or by using a specific command, like: - -.. code-block:: bash - - $ moon tenant list - -Output formats -============== - -The default output is a tabular: - -.. code-block:: bash - - $ moon tenant list - +----------------------------------+-------+---------------+--------------------------+--------------------------+ - | id | name | description | intra_authz_extension_id | intra_admin_extension_id | - +----------------------------------+-------+---------------+--------------------------+--------------------------+ - | 9fb190ddb19a4a138837e2740daec3ae | admin | Admin Project | | None | - +----------------------------------+-------+---------------+--------------------------+--------------------------+ - -But you can have other output format, use the `-f bad_value` to see them all: - -.. code-block:: bash - - $ moon tenant list -f bad_value - usage: moon tenant list [-h] [-f {csv,json,table,value,yaml}] [-c COLUMN] - [--max-width ] [--noindent] - [--quote {all,minimal,none,nonnumeric}] - moon tenant list: error: argument -f/--format: invalid choice: 'bad_value' (choose from 'csv', 'json', 'table', 'value', 'yaml') - -For example, the same command with a JSON output format: - -.. code-block:: bash - - $ moon tenant list -f json - [ - { - "intra_authz_extension_id": "", - "description": "Admin Project", - "intra_admin_extension_id": null, - "id": "9fb190ddb19a4a138837e2740daec3ae", - "name": "admin" - } - ] - -You can also select one or more columns with the `-c` attribute: - -.. code-block:: bash - - $ moon tenant list -f value -c id -c name - 9fb190ddb19a4a138837e2740daec3ae admin - -Commands -======== - -All commands can be categorized like this: -* `tenant` command to get, put or delete tenants (projects in OpenStack) -* `intraextension` command to get, put or delete intra_extensions in Moon -* `subject` `object` and `action` commands to configure subject, object or action in intra_extensions in Moon -* `rule` command to set rules in an intra_extension -* some configuration commands (`template`, `submetarule`, `aggregation`) to configure Moon and the relation in and between intra_extensions -* `log` command to show events in the Moon logging system -* `test` command to run tests against the Moon platform - -All commands can be prefixed with the command `help` to have information about usage of that command. - -Basic example: -============== - -Here is a basic example of how you can use MoonClient: - -.. code-block:: bash - - $ moon tenant list - - $ openstack project list - +----------------------------------+-----------------+ - | ID | Name | - +----------------------------------+-----------------+ - | 06f2f729f5b041f290295d2d966aff00 | alt_demo | -

-* `add` sub-command add a new intraextension -** this sub-command needs the name of the policy template to use -** the list of all policy template can be retrieve with `moon template list` -* `delete` sub-command delete an intra_extension (the deletion is definitive) -* `init` sub-command must be **only** used if the root intra_extension was deleted -** the sub-command has no effect otherwise -* `list` sub-command list all intra_extensions -* `select` sub-commands select a specific tenant so the `--intraextension` attribute is not mandatory in other commands -* `show` sub-commands print a description of the tenant given in argument -** `selected` is a special argument of the `show` sub-commands which prints the current selected tenant - -There are 3 types of intra_extension: - -* authz intra_extensions which are used to configure rules for standard actions (for example Nova or Swift actions) -* admin intra_extensions which are used to configure rules for authz and admin intra_extensions -* root intra_extensions which are used to configure rules for admin intra_extensions - -When you start using Moon, we recommend that you only configure authz intra_extensions. -Admin and root intra_extensions are already configured for your needs. - -Here is an example of how to use intra_extension: -

-When a tenant **is not connected to** an intra_extension, this tenant acts as a standard Keystone project. -Authorization rules are evaluated by each component independently. For example, when a user ask to stop a Virtual Machine (VM), -Nova - -* retrieve the Keystone token and -* check its policy.json file to see if that user can stop this VM. - -When a tenant **is connected to** an intra_extension, the authorisation process is driven by Moon. -Authorization rules are evaluated by the Moon platform. For example, when a user ask to stop a Virtual Machine (VM), -Nova - -* retrieve the Keystone token -* check its policy.json file to see if that user can stop this VM and -* ask Moon if the user is authorized to do such action. - -When a tenant is connected to an intra_extension, the authorisation process is driven by the following configuration. - -Subject/Object/Action -===================== - -The configuration of an intra_extension is mainly divided into 3 elements. -

Such a user-centric aspect helps users to define their own manner in using +OpenStack’s resources. + +###Authorization enforcement in OpenStack +As the first step, the security policy in Moon is enforced by authorization mechanism in Keystone and Nova +and Swift. +All the operations in Keystone and Nova and Swift are controlled and validated by Moon. +In OpenStack, we implemented 3 hooks respectively for Keystone and Nova and Swift, the hooks will +redirect all authorization requests to Moon and return decision from Moon. + +###Log System +Traceability and accountability are also handled in Moon, all the operations and interactions +are logged and can be consulted for any purpose. + +###Separation of management layer from OpenStack +The separation of management layer from OpenStack makes the management system totally +independent from OpenStack. We can install Moon in client’s local so that Moon can be +locally administrated by clients and remotely project their data which are hosted in +Cloud Service Provider’s datacenter. + +Scenario usage overview +======================= + +The Moon platform is built on the OpenStack Keystone component. While Keystone manages the identification +and the authentication process, Moon manages the authorisation process for all actions that comes through it. +The current version of Moon can only manage a subset of actions: actions from Nova and Swift. +For example, when a user wanted to stop a virtual machine with Nova, the authorisation for that action of stopping +is delegated through KeystoneMiddleware to the Moon platform. + +The MoonClient script helps administrators to configure the Moon platform and the authorisation rules. +It can be used like the OpenStack client with the same environment variables. + +Each OpenStack project (or tenant) car be mapped to an intra-extension. +That intra-extension will contain the configuration for the authorisation process for that tenant. +Each intra-extension is configured with subjects, objects and actions. A subject makes an action on an object. +Those elements can be placed into categories, for example a subject can have a value on the role category. +Those values are saved into the scope element. +For example, the subject (which is also called user) "admin" can have the role "admin" and "dev" on the project "admin". +The same mapping applies to the object and the action element. +For example, the action "stop a VM" can be place in a particular category "access" with the scope "write". +The action "stop a VM" is considered as the user has a write access to the VM. + +In order to grant or not an action in the system, Moon uses rules built with the scope values. +If we consider that a rule is constituted with a role for the subject category, +an ID and a security level for the object category and an access value for the action category, we can built rules +with values like the following ones: + +- admin, id1, level_high, write +- admin, id1, level_low, read +- dev, id2, level_high, read + +All configuration can be done with the MoonClient script. +If a project is not mapped to a intra-extension, it can be used as if the Moon platform doesn't exist. + +Limitations, Issues and Workarounds +=================================== + +The Moon platform can only be used to authorize Nova and Swift actions. In future releases, it could manage +more OpenStack components like Neutron, Glance, ... + +References ========== -Logs can be obtain with the `log` command: - -.. code-block:: bash - - $ moon log --number 10 - +---------------------+---------------------------------------------------------------------------------------------------------+ - | Time | Message | - +---------------------+---------------------------------------------------------------------------------------------------------+ - | 2016-08-11-12:28:58 | No Intra_Admin_Extension found, authorization granted by default. | - | | | - | 2016-08-12-03:30:05 | /MoonError/AdminException/AdminMetaData/SubjectCategoryUnknown (The given subject category is unknown.) | - | | | - | 2016-08-12-03:38:11 | /MoonError/AdminException/AdminPerimeter/SubjectUnknown (The | - | | given subject is unknown.) | - | | | - | 2016-08-12-03:48:05 | /MoonError/AdminException/AdminMetaData/SubjectCategoryUnknown (The given subject category is unknown.) | - | | | - | 2016-08-12-03:48:22 | /MoonError/AdminException/AdminPerimeter/SubjectUnknown (The | - | | given subject is unknown.) | - | | | - | 2016-08-12-03:50:59 | No Intra_Admin_Extension found, authorization granted by default. | - | | | - | 2016-08-12-03:51:38 | No Intra_Admin_Extension found, authorization granted by default. | - | | | - | 2016-08-12-03:52:01 | No Intra_Admin_Extension found, authorization granted by default. | - | | | - | 2016-08-12-03:52:08 | No Intra_Admin_Extension found, authorization granted by default. | - | | | - | 2016-08-12-03:54:52 | No Intra_Admin_Extension found, authorization granted by default. | - | | | - +---------------------+---------------------------------------------------------------------------------------------------------+ - -In this example, we limit the number of events to 10. -You can filter with a particular string or search by date.
