Hi everybody,
As a bit of a novice, I'm trying to use OpenStack SDK 0.13 in an OPNFV/ONAP project (Auto).
I'm able to use the compute and network proxies, but have problems with the identity proxy,
so I can't create projects and users.
With network, I can create a network, a router, router interfaces, but can't add a gateway to a router. Also, deleting a router fails.
With compute, I can't create flavors, and not sure if there is a "create_image" method ?
Specific issues are listed below with more details.
Any pointers (configuration, installation, usage, ...) and URLs to examples and documentation would be welcome.
For documentation, I've been looking mostly at:
https://docs.openstack.org/openstacksdk/latest/user/proxies/network.html
https://docs.openstack.org/openstacksdk/latest/user/proxies/compute.html
https://docs.openstack.org/openstacksdk/latest/user/proxies/identity_v3.html
Thanks in advance,
Gerard
For all code, import statement and Connection creation is as follows (constants defined before):
import openstack
conn = openstack.connect(cloud=OPENSTACK_CLOUD_NAME, region_name=OPENSTACK_REGION_NAME)
1) problem adding a gateway (external network) to a router:
not sure how to build a dictionary body (couldn't find examples online)
tried this:
network_dict_body = {'network_id': public_network.id}
and this (from looking at a router printout):
network_dict_body = {
'external_fixed_ips': [{'subnet_id' : public_subnet.id}],
'network_id': public_network.id
}
in both cases, tried this command:
conn.network.add_gateway_to_router(onap_router,network_dict_body)
getting the error:
Exception: <class 'TypeError'> add_gateway_to_router() takes 2 positional arguments but 3 were given
printing the router gave this:
openstack.network.v2.router.Router(distributed=False, tenant_id=03aa47d3bcfd48199e0470b1c86a7f5b, created_at=2018-05-01T01:16:08Z, external_gateway_info=None, status=ACTIVE, availability_zone_hints=[], ha=False, tags=[], description=Router created for ONAP, admin_state_up=True, revision=1, flavor_id=None, id=b923fba5-5027-47b6-b679-29c331ac1aba, updated_at=2018-05-01T01:16:08Z, routes=[], name=onap_router, availability_zones=[])
2) problem deleting routers:
onap_router = conn.network.find_router(ONAP_ROUTER_NAME)
conn.network.delete_router(onap_router.id)
(same if conn.network.delete_router(onap_router))
getting the error:
Exception: <class 'AttributeError'> 'NoneType' object has no attribute '_body'
printing the router that had been created gave this:
openstack.network.v2.router.Router(description=Router created for ONAP, status=ACTIVE, routes=[], updated_at=2018-05-01T01:16:11Z, ha=False, id=b923fba5-5027-47b6-b679-29c331ac1aba, external_gateway_info=None, admin_state_up=True, availability_zone_hints=[], tenant_id=03aa47d3bcfd48199e0470b1c86a7f5b, name=onap_router, availability_zones=['nova'], tags=[], revision=3, distributed=False, flavor_id=None, created_at=2018-05-01T01:16:08Z)
3) problem reaching the identity service:
(although I can reach compute and network services, and although there are users and projects in the Openstack instance: "admin" and "service" projects, "ceilometer", "nova", etc. (and "admin") users)
print("\nList Users:")
i=1
for user in conn.identity.users():
print('User',str(i),'\n',user,'\n')
i+=1
getting the error:
List Users:
Exception: <class 'openstack.exceptions.NotFoundException'> NotFoundException: 404
print("\nList Projects:")
i=1
for project in conn.identity.projects():
print('Project',str(i),'\n',project,'\n')
i+=1
also getting an error, but not the same as users:
List Projects:
Exception: <class 'AttributeError'> 'Proxy' object has no attribute 'projects'
if trying to create a project:
onap_project = conn.identity.find_project(ONAP_TENANT_NAME)
if onap_project != None:
print('ONAP project/tenant already exists')
else:
print('Creating ONAP project/tenant...')
onap_project = conn.identity.create_project(
name = ONAP_TENANT_NAME,
description = ONAP_TENANT_DESC,
is_enabled = True)
getting the error:
Exception: <class 'AttributeError'> 'Proxy' object has no attribute 'find_project'
4) problem creating flavors:
tiny_flavor = conn.compute.find_flavor("m1.tiny")
if tiny_flavor != None:
print('m1.tiny Flavor already exists')
else:
print('Creating m1.tiny Flavor...')
tiny_flavor = conn.compute.create_flavor(
name = 'm1.tiny',
vcpus = 1,
disk = 1,
ram = 512,
ephemeral = 0,
#swap = 0,
#rxtx_factor = 1.0,
is_public = True)
(by the way, maybe swap and rxtx are not supposed to be set ?)
getting the error:
Exception: <class 'AttributeError'> 'NoneType' object has no attribute '_body'
5) how to create images ?
there is a compute proxy method: find_image()
but it looks like there is no create_image() ?
say you wanted to add this image: Ubuntu Server 16.04 LTS (Xenial Xerus)
https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-disk1.img
how would you do it ?
