Hi Team, As part of enhancing our OpenStack RBAC policy management, we are in the process of setting up custom roles for various admin-related activities. Custom Roles Used: admin_instance_read,admin_volume_read,admin_network_read,admin_glance_read Policy Customizations: # Compute - List all instances across tenants "os_compute_api:servers:index:get_all_tenants": "rule:context_is_admin or role:admin_instance_read" "os_compute_api:servers:detail:get_all_tenants": "rule:context_is_admin or role:admin_instance_read" # Network - Get networks (shared/external/own project) "get_network": "(rule:admin_only) or (role:reader and project_id:%(project_id)s) or rule:shared or rule:external or rule:context_is_advsvc or role:admin_network_read" # Volume - List all volumes and snapshots across projects "volume:get_all": "rule:xena_system_admin_or_project_reader or role:admin_volume_read" "volume:get_all_snapshots": "rule:xena_system_admin_or_project_reader or role:admin_volume_read" # Image - List all images including shared/community/public "get_image": "role:admin or (role:reader and project_id:%(project_id)s) or project_id:%(member_id)s or 'community':%(visibility)s or 'public':%(visibility)s or 'shared':%(visibility)s or role:admin_glance_read" "get_images": "role:admin or (role:reader and project_id:%(project_id)s) or role:admin_glance_read" Issue: Despite the above configurations, listing all instances, images, volumes, and networks across all projects still only works for the admin role. The custom roles (e.g., admin_instance_read, etc.) are not taking effect for cross-project visibility as expected. Request: I would appreciate any suggestions or insights on: Whether additional policy bindings or role scopes are required. If any service-specific constraints might be overriding the custom roles. Any known limitations regarding get_all_tenants behavior with custom roles.
