Explain the difference between quantum quota-list and quota-show commands

Help page for quantum quota-list says:

ubuntu@devstack1:~/sneha/tempest/tempest/api/network$ quantum help quota-list

[--request-format {json,xml}]

List defined quotas of all tenants.

ubuntu@devstack1:~/sneha/tempest/tempest/api/network$

The description of quota-list command says that "List defined quotas of all tenants"
but the output is of only the admin tenant whose credentials are used for listing

Accidentally marked the status as "solved". Apologies for the spam.

$ quantum quota-show -h
usage: quantum quota-show [-h] [-f {shell,table}] [-c COLUMN]
                          [--variable VARIABLE] [--prefix PREFIX]
                          [--request-format {json,xml}]
                          [--tenant-id tenant-id]

Show quotas of a given tenant

quota-show is used to show the 'quotas' of a given tenant, the quota-list is used to show the 'defined quotas' of tenants.

so quota-list will be empty if there are no tenants have defined quotas. i.e. quota-list does not list the quotas of tenants who does not have defined quotas.

quota-update is used to define quotas of a tenant if u want the tenant not to use default quotas.

Using Keystone, I am able to get list of all the tenants present.

ubuntu@devstack1:~/raj/wed/tempest/tempest/api$ keystone tenant-list
+----------------------------------+--------------------+---------+
| id | name | enabled |
+----------------------------------+--------------------+---------+
| 70e75c24bd8b4f7884f073dd4510a9fa | admin | True |
| 538c09d56f0d4e22827b5da671f5dc99 | alt_demo | True |
| 6b7d64126a3c4b019cf35b8f8418b818 | demo | True |
| 33de0602d49440c7a5e8739b02b5558c | invisible_to_admin | True |
| 05b202439e334aaab73250ae393dff88 | service | True |
+----------------------------------+--------------------+---------+

Now when I request for quota-show of tenant "demo"(6b7d64126a3c4b019cf35b8f8418b818), I am able to view the defined quotas.

ubuntu@devstack1:~/raj/wed/tempest/tempest/api$ quantum quota-show --tenant-id 6b7d64126a3c4b019cf35b8f8418b818
+---------------------+-------+
| Field | Value |
+---------------------+-------+
| floatingip | 50 |
| network | 10 |
| port | 50 |
| router | 10 |
| security_group | 10 |
| security_group_rule | 100 |
| subnet | 10 |
+---------------------+-------+

But the quota values for the same tenant "demo" i.e 6b7d64126a3c4b019cf35b8f8418b818 thought they are defined, they are not appearing in the response of quota-list:

ubuntu@devstack1:~/raj/wed/tempest/tempest/api$ quantum quota-list
+------------+---------+------+--------+----------------+---------------------+--------+----------------------------------+
| floatingip | network | port | router | security_group | security_group_rule | subnet | tenant_id |
+------------+---------+------+--------+----------------+---------------------+--------+----------------------------------+
| 50 | 10 | 70 | 10 | 10 | 100 | 10 | 70e75c24bd8b4f7884f073dd4510a9fa |
+------------+---------+------+--------+----------------+---------------------+--------+----------------------------------+
ubuntu@devstack1:~/raj/wed/tempest/tempest/api$

Only the values of admin tenant user appear.
