Cloudwatt Compute Driver Documentation¶
RunAbove is a public cloud offer created by OVH Group with datacenters in North America and Europe.
RunAbove driver uses the OVH/RunAbove API so for more information about that, please refer to RunAbove knowledge base page and API console.
Instantiating a driver¶
When you instantiate a driver you need to pass the following arguments to the driver constructor:
user_id
- Application keysecret
- Application secretex_consumer_key
- Consumer key
For get application key and secret, you must first register an application at https://api.runabove.com/createApp/. Next step, create a consumer key with following command:
curl -X POST \
-H 'X-Ra-Application: youApplicationKey' \
-H 'Content-Type: application/json' \
-d '{
"accessRules":
[
{"method":"GET","path":"/*"},
{"method":"POST","path":"/*"},
{"method":"DELETE","path":"/*"},
{"method":"PUT","path":"/*"},
],
"redirection":"http://runabove.com"
}' \
"https://api.runabove.com/1.0/auth/credential"
This will answer a JSON like below with inside your Consumer Key and
validationUrl
. Follow this link for valid your key.
{
"validationUrl":"https://api.runabove.com/login/?credentialToken=fIDK6KCVHfEMuSTP3LV84D3CsHTq4T3BhOrmEEdd2hQ0CNcfVgGVWZRqIlolDJ3W",
"consumerKey":"y7epYeHCIqoO17BzBgxluvB4XLedpba9",
"state":"pendingValidation"
}
Now you have and can use you credentials with Libcloud.
Examples¶
Create instance¶
from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver
RunAbove = get_driver(Provider.RUNABOVE)
driver = RunAbove('yourAppKey', 'yourAppSecret', 'YourConsumerKey')
image = [i for i in driver.list_images() if 'Debian 8' == i.name][0]
size = [s for s in driver.list_sizes() if s.name == 'ra.s'][0]
location = [l for l in driver.list_locations() if l.id == 'SBG-1'][0]
node = driver.create_node(name='yournode', size=size, image=image,
location=location)

Parameters: - size (
int

-
delete_image
(node_image)¶ Deletes a node image from a provider.
Parameters: node_image ( NodeImage

if delete_image was successful,False
otherwise.Return type: bool
-
delete_key_pair
(name, location)[source]¶ Delete an existing key pair.
Parameters: key_pair (:class.KeyPair` or int
) – Key pair object or ID.Returns: True of False based on success of Keypair deletion Return type: bool
-
deploy_node
(**kwargs)¶ Create a new node, and start deployment.
In order to be able to SSH into a created node access credentials are required.
A user can pass either a
NodeAuthPassword
orNodeAuthSSHKey
to theauth
argument. If thecreate_node
implementation supports that kind if credential (as declared inself.features['create_node']
) then it is passed on tocreate_node
. Otherwise it is not passed on tocreate_node
and it is only used for authentication.If the
auth
parameter is not supplied but the driver declares it supportsgenerates_password
then the password returned bycreate_node
will be used to SSH into the server.Finally, if the
ssh_key_file
is supplied that key will be used to SSH into the server.This function may raise a
DeploymentException
, if a create_node call was successful, but there is a later error (like SSH failing or timing out). This exception includes a Node object which you may want to destroy if incomplete deployments are not desirable.>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> from libcloud.compute.deployment import ScriptDeployment >>> from libcloud.compute.deployment import MultiStepDeployment >>> from libcloud.compute.base import NodeAuthSSHKey >>> driver = DummyNodeDriver(0) >>> key = NodeAuthSSHKey('...') # read from file >>> script = ScriptDeployment("yum -y install emacs strace tcpdump") >>> msd = MultiStepDeployment([key, script]) >>> def d(): ... try: ... driver.deploy_node(deploy=msd) ... except NotImplementedError: ... print ("not implemented for dummy driver") >>> d() not implemented for dummy driver
Deploy node is typically not overridden in subclasses. The existing implementation should be able to handle most such.
