$ pip install cloudsigma $ wget http://goo.gl/fjdtQL -O ~/.cloudsigma.conf $ chmod 600 ~/.cloudsigma.conf $ vim ~/.cloudsigma.conf Add your credentials and the DC. Step 1: Installation 

Let’s make it easier to work with bytes $ pip install bitmath Step 1: Installation (cont’d) 

Import the library >>> import cloudsigma Import bitmath as well >>> import bitmath Access drive and server objects easier >>> drive = cloudsigma.resource.Drive() >>> server = cloudsigma.resource.Server() Step 2: The basics 

Let’s create a 10GiB drive template >>> disk_template = { 'name': ‘Test Drive', 'size': bitmath.GiB(10).bytes, 'media': 'disk' } And then create it… >>> my_disk = drive.create(disk_template) Step 2: Create a drive API section: https://cloudsigma-docs.readthedocs.org/en/latest/drives.html 

Let’s create a server template with the drive attached >>> server_template = { 'name': 'Test Server', 'cpu': 2000, 'mem': bitmath.GiB(2).bytes, 'vnc_password': 'test_server', 'drive': [{ 'boot_order': 1, 'dev_channel': '0:0', 'device': 'virtio', 'drive': my_disk['uuid'] }], 'nics': [{ 'ip_v4_conf': { 'conf': 'dhcp', 'ip': None }, 'model': 'virtio', 'vlan': None }] } Step 2: Create a server API section: https://cloudsigma-docs.readthedocs.org/en/latest/servers.html 

Now create the server >>> test_server = server.create(server_template) Step 2: Create a server (cont’d) API section: https://cloudsigma-docs.readthedocs.org/en/latest/servers.html 

Starting the server is a breeze >>> server.start(test_server[‘uuid’]) Please note that this server won’t get very far, since we’re booting off of an empty drive. You probably want to clone an existing marketplace drive (next slide) for your OS partition. Step 3: Start the server API section: https://cloudsigma-docs.readthedocs.org/en/latest/servers.html 

Clone a drive >>> my_clone = drive.clone(uuid {'name': ‘Foobar’}) Resize a the clone to 20GiB >>> my_clone[‘size’] = bitmath.GiB(20).bytes >>> drive.update(my_clone[‘uuid’], my_clone) What’s next?
