module: neutron_rbac_policies_info
short_description: Fetch Neutron policies.
author: OpenStack Ansible SIG
description:
- Get RBAC policies against a network, security group or a QoS Policy for one or more projects.
- If a C(policy_id) was not provided, this module will attempt to fetch all available policies.
- Accepts same arguments as OpenStackSDK network proxy C(find_rbac_policy) and C(rbac_policies) functions which are ultimately passed over to C(RBACPolicy)
- All parameters passed in to this module act as a filter for when no C(policy_id) was provided, otherwise they're ignored.
- Returns None if no matching policy was found as opposed to failing.
options:
policy_id:
description:
- The RBAC policy ID
- If provided, all other filters are ignored
type: str
object_id:
description:
- The object ID (the subject of the policy) to which the RBAC rules applies
- This would be the ID of a network, security group or a qos policy
- Mutually exclusive with the C(object_type)
type: str
object_type:
description:
- Can be one of the following object types C(network), C(security_group) or C(qos_policy)
- Mutually exclusive with the C(object_id)

type: str
target_project_id:
description:
- Filters the RBAC rules based on the target project id
- Logically AND'ed with other filters
- Mutually exclusive with C(project_id)
type: str
project_id:
description:
- Filters the RBAC rules based on the project id to which the object belongs to
