About

Ionosphere - library to create Azure Resource Manager Templates descriptions (Ionosphere is porting of troposphere)

The Ionosphere library allows for easier creation of the Azure Resource Manager templates JSON by writing Python code to describe the Azure resources.

To facilitate catching ARM templates or JSON errors early the library has property and type checking built into the classes.

Currently supported Azure resource types

  • Virtual Machine
  • Virtual Machine Extension
  • Virtual Machine Scale Sets
  • Virtual Machine Scale Set Extension
  • Virtual Network
  • Public IP Address
  • Network Interface
  • Network SecurityGroup
  • Application Security Group
  • Load Balancer
  • Dns Zone
  • Application Gateway
  • Storage Account

Example

The following example will generate an ARM Template that creates a VNet and an Ubuntu VM with a public IP. The template also exposes port 22 on the VM to the internet.

# Create the object
template = ARMTemplate()

# Create VNET object
vnet = VirtualNetwork("myvnet",
                      addressSpace=AddressSpace(addressPrefixes=['10.0.0.0/24']),
                      subnets=[Subnet('main_subnet', addressPrefix='10.0.0.0/24')],
                      tags={'key1': 'tag-key1', 'key2': 'tag-key2'})

# Create Network Security Group object with "Allow SSH" rule
nsg = NetworkSecurityGroup("myNsg",
                           securityRules=[
                               SecurityRule('ssh',
                                            description='public ssh access',
                                            protocol='Tcp',
                                            destinationPortRange="22",
                                            destinationAddressPrefix="*",

                                            sourcePortRange='*',

                                            direction='Inbound',
                                            priority=200

# Create Public IP Address object
publicIp = PublicIPAddress('my_vm_nic1_pubip', publicIPAllocationMethod='dynamic')

# Create Network Interface object
networkInterface = NetworkInterface('myvm_nic1',
