CloudStack is an open source cloud computing platform that allows management of virtual servers and storage. SaltStack allows configuration management of those servers. Libcloud provides a Python API to interface with multiple cloud providers including CloudStack. The Salt Cloud module uses libcloud to provision nodes on CloudStack and configure them using SaltStack. This allows defining profiles for nodes to deploy on CloudStack and provisioning them using Salt Cloud commands.

6. Salt Cloud

7. libcloud
• Python module that
provides a Cloud
Provider API abstraction
• Ability to write apps
using multiple providers
• Now with an improved
CloudStack driver

8. libcloud
conn=Driver(key=apikey,secret=sec
retkey,secure=True,host=host,path
=path)
conn.list_locations()
conn.list_images()
conn.list_sizes()
conn.create_node(name=’foobar',im
age=images[0],size=offerings[0])

11. Defining
a Provider
providers:
exoscale:
apikey: <api key>
secretkey: <secret key>
host: api.exoscale.ch
path: /compute
securitygroup: default
user: root
private_key: /path/to/private/key
provider: cloudstack

12. Node Profiles
ubuntu-exoscale-master:
provider: exoscale
image: 1d16c78d-268f-47d0-be0c-b80d31e765d2
size: b6cd1ff5-3a2f-4e9d-a4d1-8988c1191fe8
ssh_interface: public
ssh_username: root
keypair: exoscale
make_master: True
master:
user: root
interface: 0.0.0.0
ubuntu-exoscale-minion:
provider: exoscale
image: 1d16c78d-268f-47d0-be0c-b80d31e765d2
…

13. Using it
$salt-cloud –list-locations exoscale
$salt-cloud –list-images exoscale
$salt-cloud –list-sizes exoscale
$salt-cloud –p ubuntu-exoscale-master mymaster
$salt-cloud –p ubuntu-exoscale-minion myminion
