 The easiest way to get a properly constructed nova Client is with
 os-client-config:

 import os_client_config

 OS_PROJECT_NAME="d8af8a8f-a573-48e6-898a-af333b970a2d"
 OS_USERNAME="0b8c435b-cc4d-4e05-8a47-a2ada0539af1"
 OS_PASSWORD="REDACTED"
 OS_AUTH_URL="http://auth.vexxhost.net;
 OS_REGION_NAME="ca-ymq-1"

 client = os_client_config.make_client(
  'compute',
  auth_url=OS_AUTH_URL, username=OS_USERNAME,
  password=OS_PASSWORD, project_name=OS_PROJECT_NAME,
  region_name=OS_REGION_NAME)

 The upside is that the constructor interface is the same for all of the
 rest of the client libs too (just change the first argument) - and it
 will also read in OS_ env vars or named clouds from clouds.yaml if you
 have them set.

 (The 'simplest' way is to put your auth and region information into a
 clouds.yaml file like this:


 http://docs.openstack.org/developer/os-client-config/#site-specific-file-locations


 Such as:

 # ~/.config/openstack/clouds.yaml
 clouds:
vexxhost:
   profile: vexxhost
   auth:
 project_name: d8af8a8f-a573-48e6-898a-af333b970a2d
 username: 0b8c435b-cc4d-4e05-8a47-a2ada0539af1
 password: REDACTED
   region_name: ca-ymq-1


 And do:

 client = os_client_config.make_client('compute', cloud='vexxhost')


 If you don't want to do that for some reason but you'd like to construct
 a novaclient Client object by hand:


 from keystoneauth1 import loading
 from keystoneauth1 import session as ksa_session
 from novaclient import client as nova_client

 OS_PROJECT_NAME="d8af8a8f-a573-48e6-898a-af333b970a2d"
 OS_USERNAME="0b8c435b-cc4d-4e05-8a47-a2ada0539af1"
 OS_PASSWORD="REDACTED"
 OS_AUTH_URL="http://auth.vexxhost.net;
 OS_REGION_NAME="ca-ymq-1"

 # Get the auth loader for the password auth plugin
 loader = loading.get_plugin_loader('password')
 # Construct the auth plugin
 auth_plugin = loader.load_from_options(
  auth_url=OS_AUTH_URL, username=OS_USERNAME, password=OS_PASSWORD,
  project_name=OS_PROJECT_NAME)

 # Construct a keystone session
 # Other arguments that are potentially useful here are:
 #  verify - bool, whether or not to verify SSL connection validity
 #  cert - SSL cert information
 #  timout - time in seconds to use for connection level TCP timeouts
 session = ksa_session.Session(auth_plugin)

 # Now make the client
 # Other arguments you may be interested in:
 #  service_name - if you need to specify a service name for finding the
 # right service in the catalog
 #  service_type - if the cloud in question has given a different
 # service type (should be 'compute' for nova - but
 # novaclient sets it, so it's safe to omit in most cases
 #  endpoint_override - if you want to tell it to use a different URL

 #  endpoint_type - if you need to specify admin or internal

note that loaders here are generally things like load from config file, or
load from argparse arguments. If you are doing everything in a script like
this you would probably just use the keystoneauth1.identity.Password like

from keystoneauth1 import identity

auth_plugin = identity.Password(auth_url=)

 Hi!
 `novaclient.client.Client` entry-point supports almost the same
 arguments as `novaclient.v2.client.Client`. The difference is only in
 api_version, so you can set up region via `novaclient.client.Client` in
 the same way as `novaclient.v2.client.Client`.

fwiw, the second part of Monty's message is in the docs, sans region - it
would be a fairly swift change to add that and I'll probably submit a
gerrit for it soon.

Regards os_client_config,
http://docs.openstack.org/developer/os-client-config/ is great.
Unfortunately it didn't work for me in this particular case because of a
bug in novaclient, but that's beside the point - os_client_config is doing
exactly the right thing and I'm really happy with that approach in most
cases (and am changing some of our tooling to reflect that).

In http://docs.openstack.org/developer/python-novaclient/api.html
it's got some pretty clear instructions not to
use novaclient.v2.client.Client but I can't see another way to
specify the region - there's more than one in my installation, and
no param for region in novaclient.client.Client

Shall I hunt down/write a blueprint for that?

Hi!
`novaclient.client.Client` entry-point supports almost the same
arguments as `novaclient.v2.client.Client`. The difference is only in
api_version, so you can set up region via `novaclient.client.Client` in
the same way as `novaclient.v2.client.Client`.


The easiest way to get a properly constructed nova Client is with 
os-client-config:


import os_client_config

OS_PROJECT_NAME="d8af8a8f-a573-48e6-898a-af333b970a2d"
OS_USERNAME="0b8c435b-cc4d-4e05-8a47-a2ada0539af1"
OS_PASSWORD="REDACTED"
OS_AUTH_URL="http://auth.vexxhost.net;
OS_REGION_NAME="ca-ymq-1"

client = os_client_config.make_client(
'compute',
auth_url=OS_AUTH_URL, username=OS_USERNAME,
password=OS_PASSWORD, project_name=OS_PROJECT_NAME,
region_name=OS_REGION_NAME)

The upside is that the constructor interface is the same for all of the 
rest of the client libs too (just change the first argument) - and it 
will also read in OS_ env vars or named clouds from clouds.yaml if you 
have them set.


(The 'simplest' way is to put your auth and region information into a 
clouds.yaml file like this:


http://docs.openstack.org/developer/os-client-config/#site-specific-file-locations

Such as:

# ~/.config/openstack/clouds.yaml
clouds:
  vexxhost:
 profile: vexxhost
 auth:
   project_name: d8af8a8f-a573-48e6-898a-af333b970a2d
   username: 0b8c435b-cc4d-4e05-8a47-a2ada0539af1
   password: REDACTED
 region_name: ca-ymq-1


And do:

client = os_client_config.make_client('compute', cloud='vexxhost')


If you don't want to do that for some reason but you'd like to construct 
a novaclient Client object by hand:



from keystoneauth1 import loading
from keystoneauth1 import session as ksa_session
from novaclient import client as nova_client

OS_PROJECT_NAME="d8af8a8f-a573-48e6-898a-af333b970a2d"
OS_USERNAME="0b8c435b-cc4d-4e05-8a47-a2ada0539af1"
OS_PASSWORD="REDACTED"
OS_AUTH_URL="http://auth.vexxhost.net;
OS_REGION_NAME="ca-ymq-1"

# Get the auth loader for the password auth plugin
loader = loading.get_plugin_loader('password')
# Construct the auth plugin
auth_plugin = loader.load_from_options(
auth_url=OS_AUTH_URL, username=OS_USERNAME, password=OS_PASSWORD,
project_name=OS_PROJECT_NAME)

# Construct a keystone session
# Other arguments that are potentially useful here are:
#  verify - bool, whether or not to verify SSL connection validity
#  cert - SSL cert information
#  timout - time in seconds to use for connection level TCP timeouts
session = ksa_session.Session(auth_plugin)

# Now make the client
# Other arguments you may be interested in:
#  service_name - if you need to specify a service name for finding the
# right service in the catalog
#  service_type - if the cloud in question has given a different
# service type (should be 'compute' for nova - but
# novaclient sets it, so it's safe to omit in most cases
#  endpoint_override - if you want to tell it to use a different URL
#  than what the keystone catalog returns
#  endpoint_type - if you need to specify admin or internal
#  endpoints rather than the default 'public'
#  Note that in glance and barbican, this key is called
#  'interface'
client = nova_client.Client(
version='2.0', # or set the specific microversion you want
session=session, region_name=OS_REGION_NAME)

It might be clear why I prefer the os_client_config factory function 
instead - but what I prefer and what you prefer might not be the same 
thing. :)

Re: [openstack-dev] [nova] python-novaclient region setting

2016-02-21 Thread Andrey Kurilin 
Hi!
`novaclient.client.Client` entry-point supports almost the same arguments
as `novaclient.v2.client.Client`. The difference is only in api_version, so
you can set up region via `novaclient.client.Client` in the same way as
`novaclient.v2.client.Client`.
