This adds a granular policy checking framework for
placement based on nova.policy but with a lot of
the legacy cruft removed, like the is_admin and
context_is_admin rules.
A new PlacementPolicyFixture is added along with
a new configuration option, [placement]/policy_file,
which is needed because the default policy file
that gets used in config is from [oslo_policy]/policy_file
which is being used as the nova policy file. As
far as I can tell, oslo.policy doesn't allow for
multiple policy files with different names unless
I'm misunderstanding how the policy_dirs option works.
With these changes, we can have something like:
/etc/nova/policy.json - for nova policy rules
/etc/nova/placement-policy.yaml - for placement rules
The docs are also updated to include the placement
policy sample along with a tox builder for the sample.
This starts by adding granular rules for CRUD operations
on the /resource_providers and /resource_providers/{uuid}
routes which use the same descriptions from the placement
API reference. Subsequent patches will add new granular
rules for the other routes.

features:
|
|
- |
|
|
It is now possible to configure granular policy rules for placement
|
|
REST API operations.
|
|
|
|
By default, all operations continue to use the ``role:admin`` check string
|
|
so there is no upgrade impact.
|
|
|
|
A new configuration option is introduced, ``[placement]/policy_file``,
|
|
which is used to configure the location of the placement policy file.
|
|
By default, the ``placement-policy.yaml`` file may live alongside the
|
|
nova policy file, e.g.:
|
|
|
|
* /etc/nova/policy.yaml
|
|
* /etc/nova/placement-policy.yaml
|
|
|
|
However, if desired, ``[placement]/policy_file`` makes it possible to
|
|
package and deploy the placement policy file separately to make the future
|
|
split of placement and nova packages easier, e.g.:
|
|
|
|
* /etc/placement/policy.yaml
|
|
|
|
All placement policy rules are defined in code so by default no extra
|
|
configuration is required and the default rules will be used on start of
|
|
the placement service.
