OVH Compute Driver Documentation¶
OVH is an Internet Service Provider providing dedicated servers, shared and cloud hosting, domain registration, and VOIP telephony services.
OVH driver uses a REST API, for more information about that, please refer to API console.
Instantiating a driver¶
When you instantiate a driver you need to pass the following arguments to the driver constructor:
key
- Application keysecret
- Application secretex_project_id
- Project IDex_consumer_key
- Consumer key
For get application key and secret, you must register an application at https://eu.api.ovh.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://ovh.com"
}' \
https://eu.api.ovh.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://eu.api.ovh.com/auth/?credentialToken=fIDK6KCVHfEMuSTP3LV84D3CsHTq4T3BhOrmEEdd2hQ0CNcfVgGVWZRqIlolDJ3W",
"consumerKey":"y7epYeHCIqoO17BzBgxluvB4XLedpba9",
"state":"pendingValidation"
}
Secondly, you must create a cloud project and retrieve its ID, from URL for example.
Now you have and can use you credentials with Libcloud.
Examples¶
Create node¶
from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver
Ovh = get_driver(Provider.OVH)
driver = Ovh('yourAppKey', 'yourAppSecret', 'yourProjectId', 'yourConsumerKey')
location = [l for l in driver.list_locations() if l.id == 'SBG1'][0]
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 == 'vps-ssd-1'][0]
node = driver.create_node(name='yournode', size=size, image=image,
location=location)
Create and attach a volume to a node¶
from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver
Ovh = get_driver(Provider.OVH)
driver = Ovh('yourAppKey', 'yourAppSecret', 'youProjectId', 'yourConsumerKey')
location = [l for l in driver.list_locations() if l.id == 'SBG1'][0]
node = driver.list_nodes()[0]
volume = driver.create_volume(size=10, location=location)
driver.attach_volume(node=node, volume=volume)

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
