Answer 1

Easiest is to use a Rest client to login and just take the token from the response. I like the Firefox RESTClient add-on but you can use any client you want.

• Post a request to the Openstack Identity URL:

  POST keystone_ip:port/version/tokens
  

  (e.g. 127.0.0.1:5000/v2.0/tokens)

  with header:

  Content-Type: application/json
  

  and body:

  {
      "auth": {
          "tenantName": "enter_your_tenantname",
          "passwordCredentials": {
              "username": "enter_your_username",
              "password": "enter_your_password"
          }
      }
  }
  

  Note: If you're not sure what is the correct identity (keystone) URL you can log in manually to Horizon and look for a list of API endpoints.

• The response body will include something like this:

  {
      "token": {
          "issued_at": "2014-02-25T08:34:56.068363",
          "expires": "2014-02-26T08:34:55Z",
          "id": "529e3a0e1c375j498315c71d08134837"
      }
  }
  

• Use the returned token id as a header in new rest calls. For example, to get a list of servers use request:

  GET compute_endpoint_ip:port/v2/tenant_id/servers
  

  with Headers:

  X-Auth-Token: 529e3a0e1c375j498315c71d08134837
  Content-Type: application/json

As an example of how to get at it:

import keystoneclient.v2_0.client as ksclient
# authenticate with keystone to get a token

keystone = ksclient.Client(auth_url="http://192.168.10.5:35357/v2.0",
                           username="admin",
                           password="admin",
                           tenant_name="admin")


token = keystone.auth_ref['token']['id']

# use this token for whatever other services you are accessing.
print token
