cloudstack / saltstack lightning talk at devops amsterdam
DESCRIPTION
This is my lightning talk from DevOps days Amsterdam on June 14th. I present a quick hack I did during LinuxTag berlin. Saltstack is an alternative to Puppet and Chef, written in Python it has an active community and is easy to use. Saltstack has a cloud client called salt-cloud which can use apache libcloud to interact with Cloud providers. I created a coudstack driver in saltstack and patched libcloud to be able to use salt on a CloudStack cloud. This talk lasted 5 minutes as per the rules of DevOps Lightning talk.TRANSCRIPT

Salt Cloud
libcloud
• Python module that provides a Cloud Provider API abstraction
• Ability to write apps using multiple providers
• Now with an improved CloudStack driver
libcloud
conn=Driver(key=apikey,secret=secretkey,secure=True,host=host,path=path)
conn.list_locations()
conn.list_images()
conn.list_sizes()
conn.create_node(name=’foobar',image=images[0],size=offerings[0])
