Re: [openstack-dev] [sdk] issues with using OpenStack SDK Python client
Many thanks !
Adding a gateway to a router: it looks like it works in the router creation
method, but not in the router update method.
(i.e., passing a external_gateway_info dictionary in
conn.network.create_router() worked,
but doing the same with conn.network.add_gateway_to_router() did not work)
the (verbose) code snippet is:
external_network = conn.network.find_network(EXTERNAL_NETWORK_NAME)
onap_gateway_external_subnets = []
for ext_subn_id in external_network.subnet_ids:
onap_gateway_external_subnets.append({'subnet_id':ext_subn_id})
network_dict_body = {
'network_id': external_network.id,
'enable_snat': True,
'external_fixed_ips': onap_gateway_external_subnets}
onap_router = conn.network.create_router(
name = ONAP_ROUTER_NAME,
description = ONAP_ROUTER_DESC,
external_gateway_info = network_dict_body,
is_admin_state_up = True)
I got the idea of trying at creation time, from the create_router API
(external_gateway_info entry) at
https://developer.openstack.org/api-ref/network/v2/#layer-3-networking
(thanks for the tip!)
So there might be a difference between how network.create_router() handles this
external_gateway_info,
versus how network.add_gateway_to_router() handles it.
About identity_api_version in clouds.yaml:
yep, that works !
About the "!=None" comparison problem: OK, thanks for the fixing effort in
progress !

[openstack-dev] [sdk] identity proxy: users, groups, projects, membership, roles
Hi, I'm wondering if there are (or should be) operations in the Connection.identity proxy to manage user and group membership to projects, and to manage user and group role assignments (there are role management methods in the Project class, but I couldn't find them in the identity proxy): The 8 operations could be something like that: add|remove user|group to|from project (i.e., manage 'Member' role for projects) assign|unassign role to|from user|role (any role) Project operations: Connection.identity.add_user_to_project(user, project, ) user: instance or id project: project or id Connection.identity.remove_user_from_project(user, project, ) Connection.identity.add_group_to_project(group, project, ) group: instance or id Connection.identity.remove_group_from_project(group, project, ) Role operations: Connection.identity.assign_role_to_user(role, user, ) Connection.identity.unassign_role_from_user(role, user, ) Connection.identity.assign_role_to_group(role, group, ) Connection.identity.unassign_role_from_group(role, group, ) Cheers, Gerard The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain proprietary, confidential or privileged information.

Re: [openstack-dev] [sdk] issues with using OpenStack SDK Python client
Many thanks for the welcome ;)
And many thanks for the speedy and very useful response !
Details below.
Best regards,
Gerard
For add_gateway_to_router():
So I tried this:
external_network = conn.network.find_network(EXTERNAL_NETWORK_NAME)
network_dict_body = {'network_id' : external_network.id}
conn.network.add_gateway_to_router(onap_router, **network_dict_body)
==> no errors, but the router is not updated (no gateway is set)
(external_gateway_info is still None)
(same with conn.network.add_gateway_to_router(onap_router,
network_id=external_network.id) )
Is the body parameter for add_gateway_to_router() expected to correspond to a
Network ?
(from a router point of view, a "gateway" is an external network)
Should the network's subnet(s) be also specified in the dictionary ? Maybe only
if certain specific subnets are desired for the gateway role. Otherwise,
the default would apply: there is usually only 1 subnet, and that's the one
to be used. So network_id would be enough to specify a gateway used in a
standard way.
Maybe more details about what is expected in this body dictionary should be
documented
in the add_gateway_to_router() section?
In Horizon, when selecting a router, and selecting "Set Gateway", the user is
only
asked to pick an external network from a dropdown list. Then, a router
interface is
implicitly created, with an IP@ picked from the subnet of that network.
For router deletion: it looks like it's the "!= None" test on the returned
object that has an issue
onap_router = conn.network.find_router(ONAP_ROUTER_NAME)
if onap_router != None:
print('Deleting ONAP router...')
conn.network.delete_router(onap_router.id)
else:
print('No ONAP router found...')
I added traceback printouts in the code.
printing the router before trying to delete it:
onap_router:

For identity_api_version=3 :
yes, that worked !
Could that identity_api_version parameter also/instead be specified in the
clouds.yaml file ?

For the image creation:
ah, OK, indeed, there is an image proxy (even 2: v1, v2),
and maybe the compute / image operations are redundant (or maybe not, for
convenience) ?
and yes, it worked ! There was no need for additional parameters.

[openstack-dev] [sdk] issues with using OpenStack SDK Python client
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: 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: '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: 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: '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: '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: '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_ima
