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.
