Open Stack

Red Hat did really good documentation on security (and policies) which can be easily used with kolla - thanks to that my policies now work: 

https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/13/pdf/security_and_hardening_guide/Red_Hat_OpenStack_Platform-13-Security_and_Hardening_Guide-en-US.pdf <https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/13/pdf/security_and_hardening_guide/Red_Hat_OpenStack_Platform-13-Security_and_Hardening_Guide-en-US.pdf>

Best regards,

If I override (for example keystone_policy.json) with  a file placed in /etc/kolla/config/horizon which contains only 3 rules, then after kolla-ansible reconfigure inside horizon container there is of course keystone_police.json file, but only with my 3 rules - should I assume, that previously seen default rules (other than the ones overridden by my rules) still works, whether I see them in the file or not?

So I create „project_admin” role and assign it to this user. Then I found /etc/kolla/keystone/policy.json.test file, which I use as template. There is rule „identity:create_credential” : „(role:admin and system_scope:all)” so I add „or role:project_admin” and put file in /etc/kolla/config/keystone/ and reconfigure kolla. And now few questions:
