implements 100% (or less ;) ) of the Reddwarf API.

Command-line API
----------------
TODO: Add docs
To use the command line API, first log in using your user name, api key,
tenant, and appropriate auth url.
Python API
----------
.. code-block:: bash
$ reddwarf-cli --username=jsmith --apikey=abcdefg --tenant=12345 --auth_url=http://reddwarf_auth:35357/v2.0/tokens auth login
At this point you will be authenticated and given a token, which is stored
at ~/.apitoken. From there you can make other calls to the CLI.

Using the Client Programmatically
=================================
.. testsetup::
# Creates some vars we don't show in the docs.
AUTH_URL="http://localhost:8779/v1.0/auth"
from reddwarfclient import Dbaas
from reddwarfclient import auth
class FakeAuth(auth.Authenticator):
def authenticate(self):
class FakeCatalog(object):
def __init__(self, auth):
self.auth = auth
def get_public_url(self):
return "%s/%s" % ('http://localhost:8779/v1.0',
self.auth.tenant)
def get_token(self):
return self.auth.tenant
return FakeCatalog(self)
from reddwarfclient import Dbaas
OLD_INIT = Dbaas.__init__
def new_init(*args, **kwargs):
kwargs['auth_strategy'] = FakeAuth
OLD_INIT(*args, **kwargs)
# Monkey patch init so it'll work with fake auth.
Dbaas.__init__ = new_init
client = Dbaas("jsmith", "abcdef", tenant="12345",
auth_url=AUTH_URL)
client.authenticate()
# Delete all instances.
instances = [1]
while len(instances) > 0:
instances = client.instances.list()
for instance in instances:
try:
instance.delete()
except:
pass
flavor_id = "1"
for i in range(30):
name = "Instance #%d" % i
client.instances.create(name, flavor_id, None)
Authentication
--------------
Authenticating is necessary to use every feature of the client (except to
discover available versions).
To create the client, create an instance of the Dbaas (Database as a Service)
class. The auth url, auth user, key, and tenant ID must be specified in the
call to the constructor.
.. testcode::
from reddwarfclient import Dbaas
global AUTH_URL
client = Dbaas("jsmith", "abcdef", tenant="12345",
auth_url=AUTH_URL)
client.authenticate()
The default authentication strategy assumes a Keystone complaint auth system.
For Rackspace auth, use the keyword argument "auth_strategy='rax'".
Versions
--------
You can discover the available versions by querying the versions property as
follows:
.. testcode::
versions = client.versions.index("http://localhost:8779")
The "index" method returns a list of Version objects which have the ID as well
as a list of links, each with a URL to use to reach that particular version.
.. testcode::
for version in versions:
print(version.id)
for link in version.links:
if link['rel'] == 'self':
print(" %s" % link['href'])
.. testoutput::
v1.0
http://localhost:8779/v1.0
Instances
---------
The following example creates a 512 MB instance with a 1 GB volume:
.. testcode::
client.authenticate()
flavor_id = "1"
volume = {'size':1}
databases = [{"name": "my_db",
"character_set": "latin2", # This and the next field are
"collate": "latin2_general_ci"}] # optional.
users = [{"name": "jsmith", "password": "12345",
"databases": [{"name": "my_db"}]
}]
instance = client.instances.create("My Instance", flavor_id, volume,
databases, users)
To retrieve the instance, use the "get" method of "instances":
.. testcode::
updated_instance = client.instances.get(instance.id)
print(updated_instance.name)
print(" Status=%s Flavor=%s" %
(updated_instance.status, updated_instance.flavor['id']))
.. testoutput::
My Instance
Status=BUILD Flavor=1
You can delete an instance by calling "delete" on the instance object itself,
or by using the delete method on "instances."
.. testcode::
# Wait for the instance to be ready before we delete it.
import time
from reddwarfclient.exceptions import NotFound
while instance.status == "BUILD":
instance.get()
time.sleep(1)
print("Ready in an %s state." % instance.status)
instance.delete()
# Delete and wait for the instance to go away.
while True:
try:
instance = client.instances.get(instance.id)
assert instance.status == "SHUTDOWN"
except NotFound:
break
.. testoutput::
Ready in an ACTIVE state.
Listing instances and Pagination
--------------------------------
To list all instances, use the list method of "instances":
.. testcode::
instances = client.instances.list()
Lists paginate after twenty items, meaning you'll only get twenty items back
even if there are more. To see the next set of items, send a marker. The marker
is a key value (in the case of instances, the ID) which is the non-inclusive
starting point for all returned items.
The lists returned by the client always include a "next" property. This
can be used as the "marker" argument to get the next section of the list
back from the server. If no more items are available, then the next property
is None.
.. testcode::
# There are currently 30 instances.
instances = client.instances.list()
print(len(instances))
print(instances.next is None)
instances2 = client.instances.list(marker=instances.next)
print(len(instances2))
print(instances2.next is None)
.. testoutput::
20
False
10
True
