move content from configuringservices to configuration
The content from configuringservices belongs in the general configuration guide. This results in one less file that can branch off and overlap. Change-Id: I0490818f862d982072c0adfaa1f02d7ac9c8abe3

Bootstrapping Keystone with ``keystone-manage bootstrap``
|
||||
=========================================================
|
||||
|
||||
Setting up projects, users, and roles
|
||||
-------------------------------------
|
||||
|
||||
The ``keystone-manage bootstrap`` command will create a user, project and role,
|
||||
and will assign the newly created role to the newly created user on the newly
|
||||
created project. By default, the names of these new resources will be called
|
||||
``admin``.
|
||||
|
||||
The defaults may be overridden by calling ``--bootstrap-username``,
|
||||
``--bootstrap-project-name`` and ``--bootstrap-role-name``. Each of these have
|
||||
an environment variable equivalent: ``OS_BOOTSTRAP_USERNAME``,
|
||||
``OS_BOOTSTRAP_PROJECT_NAME`` and ``OS_BOOTSTRAP_ROLE_NAME``.
|
||||
|
||||
A user password must also be supplied. This can be passed in as either
|
||||
``--bootstrap-password``, or set as an environment variable using
|
||||
``OS_BOOTSTRAP_PASSWORD``.
|
||||
|
||||
Optionally, if specified by ``--bootstrap-public-url``,
|
||||
``--bootstrap-admin-url`` and/or ``--bootstrap-internal-url`` or the equivalent
|
||||
environment variables, the command will create an identity service with the
|
||||
specified endpoint information. You may also configure the
|
||||
``--bootstrap-region-id`` and ``--bootstrap-service-name`` for the endpoints to
|
||||
your deployment's requirements.
|
||||
|
||||
.. NOTE::
|
||||
|
||||
It is strongly encouraged to configure the identity service and its
|
||||
endpoints while bootstrapping keystone.
|
||||
|
||||
Minimally, keystone can be bootstrapped with:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ keystone-manage bootstrap --bootstrap-password s3cr3t
|
||||
|
||||
Verbosely, keystone can be bootstrapped with:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ keystone-manage bootstrap \
|
||||
--bootstrap-password s3cr3t \
|
||||
--bootstrap-username admin \
|
||||
--bootstrap-project-name admin \
|
||||
--bootstrap-role-name admin \
|
||||
--bootstrap-service-name keystone \
|
||||
--bootstrap-region-id RegionOne \
|
||||
--bootstrap-admin-url http://localhost:35357 \
|
||||
--bootstrap-public-url http://localhost:5000 \
|
||||
--bootstrap-internal-url http://localhost:5000
|
||||
|
||||
This will create an ``admin`` user with the ``admin`` role on the ``admin``
|
||||
project. The user will have the password specified in the command. Note that
|
||||
both the user and the project will be created in the ``default`` domain. By not
|
||||
creating an endpoint in the catalog users will need to provide endpoint
|
||||
overrides to perform additional identity operations.
|
||||
|
||||
By creating an ``admin`` user and an identity endpoint deployers may
|
||||
authenticate to keystone and perform identity operations like creating
|
||||
additional services and endpoints using that ``admin`` user. This will preclude
|
||||
the need to ever use or configure the ``admin_token`` (described below).
|
||||
|
||||
To test a proper configuration, a user can use OpenStackClient CLI:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack project list --os-username admin --os-project-name admin \
|
||||
--os-user-domain-id default --os-project-domain-id default \
|
||||
--os-identity-api-version 3 --os-auth-url http://localhost:5000 \
|
||||
--os-password s3cr3t
|
||||
|
||||
Bootstrapping Keystone with ``ADMIN_TOKEN``
|
||||
===========================================
|
||||
|
||||
.. NOTE::
|
||||
|
||||
It is strongly recommended to configure the identity service with the
|
||||
``keystone-manage bootstrap`` command and not the ``ADMIN_TOKEN``.
|
||||
|
||||
|
||||
Admin Token
|
||||
-----------
|
||||
|
||||
For a default installation of Keystone, before you can use the REST API, you
|
||||
need to define an authorization token. This is configured in ``keystone.conf``
|
||||
file under the section ``[DEFAULT]``. In the sample file provided with the
|
||||
Keystone project, the line defining this token is::
|
||||
|
||||
[DEFAULT]
|
||||
admin_token = ADMIN
|
||||
|
||||
A "shared secret" that can be used to bootstrap Keystone. This token does not
|
||||
represent a user, and carries no explicit authorization.
|
||||
To disable in production (highly recommended), remove
|
||||
``AdminTokenAuthMiddleware`` from your paste application pipelines (for example,
|
||||
in ``keystone-paste.ini``)
|
||||
|
||||
Setting up projects, users, and roles
|
||||
-------------------------------------
|
||||
|
||||
You need to minimally define a project, user, and role to link the project and
|
||||
user as the most basic set of details to get other services authenticating
|
||||
and authorizing with Keystone.
|
||||
|
||||
You will also want to create service users for nova, glance, swift, etc. to
|
||||
be able to use to authenticate users against Keystone. The ``auth_token``
|
||||
middleware supports using either the shared secret described above as
|
||||
`admin_token` or users for each service.
|
||||
|
||||
Setting up other OpenStack Services
|
||||
===================================
|
||||
|
||||
Creating Service Users
|
||||
----------------------
|
||||
|
||||
To configure the OpenStack services with service users, we need to create
|
||||
a project for all the services, and then users for each of the services. We
|
||||
then assign those service users an ``admin`` role on the service project. This
|
||||
allows them to validate tokens - and to authenticate and authorize other user
|
||||
requests.
|
||||
|
||||
Create a project for the services, typically named ``service`` (however, the
|
||||
name can be whatever you choose):
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack project create service
|
||||
|
||||
Create service users for ``nova``, ``glance``, ``swift``, and ``neutron``
|
||||
(or whatever subset is relevant to your deployment):
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack user create nova --password Sekr3tPass --project service
|
||||
|
||||
Repeat this for each service you want to enable.
|
||||
|
||||
Create an administrative role for the service accounts, typically named
|
||||
``admin`` (however the name can be whatever you choose). For adding the
|
||||
administrative role to the service accounts, you'll need to know the
|
||||
name of the role you want to add. If you don't have it handy, you can look it
|
||||
up quickly with:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack role list
|
||||
|
||||
Once you have it, grant the administrative role to the service users.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack role add admin --project service --user nova
|
||||
|
||||
Defining Services
|
||||
-----------------
|
||||
|
||||
Keystone also acts as a service catalog to let other OpenStack systems know
|
||||
where relevant API endpoints exist for OpenStack Services. The OpenStack
|
||||
Dashboard, in particular, uses this heavily - and this **must** be configured
|
||||
for the OpenStack Dashboard to properly function.
|
||||
|
||||
The endpoints for these services are defined in a template, an example of
|
||||
which is in the project as the file ``etc/default_catalog.templates``.
|
||||
|
||||
Keystone supports two means of defining the services, one is the catalog
|
||||
template, as described above - in which case everything is detailed in that
|
||||
template.
|
||||
|
||||
The other is a SQL backend for the catalog service, in which case after
|
||||
Keystone is online, you need to add the services to the catalog:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ openstack service create compute --name nova \
|
||||
--description "Nova Compute Service"
|
||||
$ openstack service create ec2 --name ec2 \
|
||||
--description "EC2 Compatibility Layer"
|
||||
$ openstack service create image --name glance \
|
||||
--description "Glance Image Service"
|
||||
$ openstack service create identity --name keystone \
|
||||
--description "Keystone Identity Service"
|
||||
$ openstack service create object-store --name swift \
|
||||
--description "Swift Service"
|
||||
|
||||

||||

Configuring Services to work with Keystone
|
||||
==========================================
|
||||
|
||||
.. toctree::
|
||||
:maxdepth: 1
|
||||
|
||||
Once Keystone is installed and running (see :doc:`configuration`), services
|
||||
need to be configured to work with it. To do this, we primarily install and
|
||||
configure middleware for the OpenStack service to handle authentication tasks
|
||||
or otherwise interact with Keystone.
|
||||
|
||||
In general:
|
||||
|
||||
* Clients making calls to the service will pass in an authentication token.
|
||||
* The Keystone middleware will look for and validate that token, taking the
|
||||
appropriate action.
|
||||
* It will also retrieve additional information from the token such as user
|
||||
name, user id, project name, project id, roles, etc...
|
||||
|
||||
The middleware will pass those data down to the service as headers. More
|
||||
details on the architecture of that setup is described in the
|
||||
`authentication middleware documentation`_.
|
||||
|
||||
Setting up credentials with ``keystone-manage bootstrap``
|
||||
=========================================================
|
||||
|
||||
Setting up projects, users, and roles
|
||||
-------------------------------------
|
||||
|
||||
The ``keystone-manage bootstrap`` command will create a user, project and role,
|
||||
and will assign the newly created role to the newly created user on the newly
|
||||
created project. By default, the names of these new resources will be called
|
||||
``admin``.
|
||||
|
||||
The defaults may be overridden by calling ``--bootstrap-username``,
|
||||
``--bootstrap-project-name`` and ``--bootstrap-role-name``. Each of these have
|
||||
an environment variable equivalent: ``OS_BOOTSTRAP_USERNAME``,
|
||||
``OS_BOOTSTRAP_PROJECT_NAME`` and ``OS_BOOTSTRAP_ROLE_NAME``.
|
||||
|
||||
A user password must also be supplied. This can be passed in as either
|
||||
``--bootstrap-password``, or set as an environment variable using
|
||||
``OS_BOOTSTRAP_PASSWORD``.
|
||||
|
||||
Optionally, if specified by ``--bootstrap-public-url``,
|
||||
``--bootstrap-admin-url`` and/or ``--bootstrap-internal-url`` or the equivalent
|
||||
environment variables, the command will create an identity service with the
|
||||
specified endpoint information. You may also configure the
|
||||
``--bootstrap-region-id`` and ``--bootstrap-service-name`` for the endpoints to
|
||||
your deployment's requirements.
|
||||
|
||||
.. NOTE::
|
||||
|
||||
It is strongly encouraged to configure the identity service and its
|
||||
endpoints while bootstrapping keystone.
|
||||
|
||||

|
||||
|

This will create an ``admin`` user with the ``admin`` role on the ``admin``
|

|

|

|

Once you have it, grant the administrative role to the service users. This is
|
||||
all assuming that you've already created the basic roles and settings as
|
||||
described in :doc:`configuration`:
|
||||
|

Setting Up Auth-Token Middleware
|
||||
================================
|
||||
|
||||
The Keystone project provides the auth-token middleware which validates that
|
||||
the request is valid before passing it on to the application. This must be
|
||||
installed and configured in the applications (such as Nova, Glance, Swift,
|
||||
etc.). The `authentication middleware documentation`_ describes how to install
|
||||
and configure this middleware.
