Creating a Loadbalancer with the admin tenant without a explicit tenant_id failing community BVT test

[jgruber]

Agent Version

9.2.0

Operating System

RHEL 7.3

OpenStack Release

Mitaka

Bug Severity

Severity: 5

Description

According to community BVT

  neutron_lbaas.tests.tempest.v2.api.test_load_balancers_admin.LoadBalancersTestJSON.test_create_load_balancer_missing_tenant_id_field_for_admin

when a loadbalacner is created by the admin tenant and no tenant_id is explicitly specified in the loadbalancer create call, the subnet_id should be interrogated and the tenant for the neutron subnet should be used for the loadblancer.

Deployment

Run
neutron_lbaas.tests.tempest.v2.api.test_load_balancers_admin.LoadBalancersTestJSON.test_create_load_balancer_missing_tenant_id_field_for_admin

[jgruber]

Just a note.. I'm not sure the BVT test should work.

The use case to me that is important is the admin tenant can create a loadbalancer for a non-admin tenant with the loadbalancing subnet_id on a non-shared network owned by admin. This is the use case for letting a third party orchestration create a loadbalancer for a non-admin tenant with a loadbalancer on a public facing network.

This scenario results in a loadbalancer in 'ERROR' state using the Octavia loadbalancer. Our driver should pass when the admin user creates a loadbalancer for a particular tenant provided the --tenant-id parameter matches the subnet ID.

[richbrowne]

Ok, this does work on the Octavia driver. I was hitting an error in the number of loadbalancers I could create. On Octavia, I see a loadbalancer with the tenant id of the admin and a subnet tenant id of the tenant.

We need to be able to check that the user that is creating the loadbalancer is 'admin' or has admin privileges. I am not sure how the driver does this.

@dflanigan @mattgreene Could you take a look this issue? If this is supported, then I can work on it next sprint, otherwise can we close it?

[mattgreene]

This is a known limitation with the F5 product and will be addressed in a future release. Exclude from automated regression.
