Depuis la version 0.14 (encore en phase de bêta) il est possible d’utiliser Google Compute Engine. Il existe encore qq bugs que j’essaye d’aider a éliminer :
https://github.com/apache/libcloud/commit/7a04971288791a02c1c335f9d36da2f90d892b5b
Grace a libcloud il est tres facile de creer des machinnes virtuel dans les cloud public. Voila un petit exemple pour GCE, AWS et RackSpace :
def createNodeGce(iGceConex,iAmi, iInstance, iLocation):
#image = [i for i in iGceConex.list_images() if i.id == iAmi ][0]
size = [s for s in iGceConex.list_sizes() if s.name == iInstance][0]
alocation = [s for s in iGceConex.list_locations() if s.name == iLocation][0]
print("Create server with image : " + str(iAmi) + " and server type : " + str(size) + " and location : " + str(alocation))
node = iGceConex.create_node(name=GCE_INSTANCE_NAME, image=iAmi, size=size,location=alocation)
print(str(node))
return node
def createNodeAws(iAwsConex,iAmi, iInstance):
image = [i for i in iAwsConex.list_images() if i.id == iAmi ][0]
size = [s for s in iAwsConex.list_sizes() if s.id == iInstance][0]
print("Create server with image : " + str(image) + " and server type : " + str(size))
node = iAwsConex.create_node(name=EC2_INSTANCE_NAME, image=image, size=size,ex_securitygroup=EC2_SECURITY_GROUP,ex_keyname=EC2_KEY_NAME)
print(str(node))
def createNodeRackSpace(iRackConex,iAmi, iInstance):
image = [i for i in iRackConex.list_images() if i.name == iAmi ][0]
size = [s for s in iRackConex.list_sizes() if s.id == iInstance ][0]
aSshKeyFilePath = "SSH_KEY_PUBLIC"
print("Create server with image : " + str(image) + " and server type : " + str(size))
node = iRackConex.create_node(name=RACKSPACE_INSTANCE_NAME, image=image, size=size)
L’exemple complet est disponnible sur github ICI :

Tester sur une machinne Ubuntu 13 sur AWS avec l’instal suivante :
#Install setuptools. Necessaire pour pip
sudo apt-get -y install python-setuptools
#Install GIT. Necessaire pour libcloud DEV
sudo apt-get -y install git
#install PIP
curl -O https://pypi.python.org/packages/source/p/pip/pip-1.4.1.tar.gz
tar xvzf pip-1.4.1.tar.gz
cd pip-1.4.1
sudo python setup.py install
#install libcloud
sudo pip install git+https://git-wip-us.apache.org/repos/asf/libcloud.git@trunk#egg=apache-libcloud
Voila le resultat avec listing des VMs sur les 3 providers et puis creation d’une VM sur chaque provider avant de lister une nouvelle fois les VMs existente.
ubuntu@domU-12-31-39-09-54-77:~$ python test.py
Create libcloud conex obj
Then list the different provider object (to validate logins)
Listing GCE :
Listing EC2 :
Listing RackSpace :
Then list the different VMs (on each provider)
Listing GCE :
Vms :
[]
Listing EC2 :
Vms :

Then create nodes
Create server with image : <NodeImage: id=ami-ad184ac4, name=099720109477/ubuntu/images/ebs/ubuntu-saucy-13.10-amd64-server-20131015, driver=Amazon EC2 …> and server type : <NodeSize: id=t1.micro, name=Micro Instance, ram=613 disk=15 bandwidth=None price=0.02 driver=Amazon EC2 …>

Wait few seconds
Then list the different VMs again(on each provider)
