I'm trying to run some tests with libcloud for OpenStack, but getting stuck on Could not find specified endpoint issue. When I run this code:
from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver
import libcloud.security
libcloud.security.VERIFY_SSL_CERT = False
OpenStack = get_driver(Provider.OPENSTACK)
driver = OpenStack(
'admin', 'password',
ex_force_auth_url='http://controller:5000',
ex_force_auth_version='2.0_password'
)
driver.list_images()
I get this error:
Traceback (most recent call last):
File "my_script.py", line 25, in <module>

raise LibcloudError('Could not find specified endpoint')
libcloud.common.types.LibcloudError: <LibcloudError in None 'Could not find specified endpoint'>
According to the docs https://libcloud.readthedocs.org/en/latest/compute/drivers/openstack.html#i-get-could-not-find-specified-endpoint-error it seems the service catalog from OpenStack is not being filled. And that seems to be true, because this is the answer I get from the server. You can see the serviceCatalog is empty.
{
"access": {
"metadata": {
"is_admin": 0,
"roles": []
},
"serviceCatalog": [],
"token": {
"audit_ids": [
"bH-SKGBdRCWlZTtB8LcDIg"
],
"expires": "2016-04-18T20:41:38Z",
"id": "3298b08a96284dfd9473881afce659c9",
"issued_at": "2016-04-18T19:41:38.277756"
},
"user": {
"id": "74767f37d3ee4e3d92a1d0fe6d7da82f",
"name": "admin",
"roles": [],
"roles_links": [],
"username": "admin"
}
}
}
but when I run openstack catalog list command, I get this result:
+------------+----------+------------------------------------------------------------------------+
| Name | Type | Endpoints |
+------------+----------+------------------------------------------------------------------------+
| keystone | identity | RegionOne |
| | | public: http://controller:5000/v2.0 |

How do I make libcloud identify my service catalog from openstack, as it does seems to be OK, but not being fetched? Already tried using the ex_force_service_type, ex_force_service_name, ex_force_service_region with the same result. Using ex_force_auth_token and ex_force_base_url results on a 404 error.
Thanks!
Turns out it was a problem with keystone (authentication) version. It is necessary to use
ex_force_auth_version='3.x_password'
instead of
ex_force_auth_version='2.0_password'
which is not documented in the libcloud docs for OpenStack: https://libcloud.readthedocs.org/en/latest/compute/drivers/openstack.html#connecting-to-the-openstack-installation
Also had to include
ex_tenant_name='admin'
in my case to get it working. Weird part is that doing auth with v2 actually runs auth fine (I was able to get a wrong credentials message), but do not return the catalog list. Only v3 does that. Anybody can explain why that happens?
