Openstack: login as admin and retrieve server data from different tenants via python -

i'm writing cron job in python openstack should read server ids database , servers api using python-novaclient.

in pseudo code things should work this:

session = login_to_keystone(user="admin", password="something") #or use token nova_client = get_nova_client(session)  #the servers array holds dictionaries server, user , tenant ids strings # e.g. {"server_id": "1-2-3", "tentant_id": "456", user_id: "11111-2222"} server in servers:    server_obj = nova_client.servers.get(server.server_id)    ...do stuff server_obj (read data it, delete,...)... 

what i've come following, it's not right endpointnotfound exception. i'm using devstack juno.

from keystoneclient.v2_0 import client keystone_client keystoneclient import session novaclient import client nova_client  #the url admin endpoint keystone = keystone_client.client(token="my-admin-token",             auth_url="http://192.168.1.1:35357/v2.0",             endpoint="http://192.168.1.1:35357/v2.0")  key_session = session.session(auth=keystone) nova = nova_client.client(2, session=key_session)  #let's assume servers array populated server in servers:     server_obj = nova.servers.get(server.server_id) #exception happens here 

i need run admin servers can belong tenant , might deleted cron job.

thanks help!

update: information need can use admin tenant retrieving servers (regardless of owner). allows me use publicurl.

my current solution looks this:

from keystoneclient.auth.identity import v2 keystoneclient import session novaclient import client nova_client  auth = v2.password(auth_url="http://192.168.1.1:5000/v2.0",                    username="admin",                    password="my_secrete",                    tenant_name="admin") # admin's tenant  auth_session = session.session(auth=auth) nova = nova_client.client(2, session=auth_session)  server in servers:     ... stuff nova.servers.get("some id") 

in order list of servers tenants, need perform 2 tasks:

1. log in user admin privileges, and
2. tell nova api want list of servers tenants.

logging in admin user

it looks you're trying use admin_token defined in keystone.conf authentication. may work, mechanism meant means of bootstrapping keystone. when interacting other services, meant log in using username/password pair has been defined in keystone admin credentials. think @anoop.babu has given work fine:

>>> nova = nova_client.client('2', username, password,                               project_id, auth_url) 

where:

• username = admin
• password = password_for_admin_user
• project_id = admin
• auth_url = http://your_api_server:5000/v2.0

we can test client out using like:

>>> nova.hypervisors.list() [<hypervisor: 2>] 

that tells we've authenticated successfully.

listing servers

if called nova.servers.list(), asking list of nova servers owned admin tenant, should empty:

>>> nova.servers.list() [] 

in order see servers other tenants, need pass all_tenants search option:

>>> nova.servers.list(search_opts={'all_tenants':1}) [<server: cirros0>] 

and should want be.
