# azure\_virtual\_machine
|
||
|
||
Use the `azure_virtual_machine` InSpec audit resource to ensure that a Virtual Machine has been provisioned correctly.
|
||
|
||
## Syntax
|
||
|
||
The name of the machine and the resource group are required as properties to the resource.
|
||
|
||
describe azure_virtual_machine(group_name: 'MyResourceGroup', name: 'MyVM') do
|
||
its('property') { should eq 'value' }
|
||
end
|
||
|
||
where
|
||
|
||
* `MyVm` is the name of the virtual machine as seen in Azure; it is **not** the hostname of the machine
|
||
* `MyResourceGroup` is the name of the machine's resource group
|
||
* `property` is one of the resource properties
|
||
* `value` is the expected output from the matcher
|
||
|
||
## Examples
|
||
|
||
The following examples show to use this InSpec audit resource.
|
||
|
||
### Check that the first data disk is of the correct size
|
||
|
||
describe azure_virtual_machine_data_disk(group_name: 'InSpec-Azure', name: 'Linux-Internal-VM').where(number: 1) do
|
||
its('size') { should cmp >= 15 }
|
||
end
|
||
|
||
<br>
|
||
|
||
## Parameters
|
||
|
||
* `group_name`, `name`, `apiversion`
|
||
|
||
## Parameter Examples
|
||
|
||
The options that can be passed to the resource are as follows.
|
||
|
||
### group_name (required)
|
||
|
||
Use this parameter to define the Azure Resource Group to be tested.
|
||
|
||
describe azure_virtual_machine_data_disk(group_name: 'InSpec-Azure') do
|
||
...
|
||
end
|
||
|
||
### name
|
||
|
||
Use this parameter to define the name of the Azure resource to test.
|
||
|
||
describe azure_virtual_machine_data_disk(group_name: 'InSpec-Azure', name: 'Windows-Internal-VM') do

|
||
its('computer_name') { should cmp 'win-internal-1' }
|
||
|

### nic\_count

### connected\_nics
|

|
||
This returns an array of the NIC ids that are connected to the machine. This means that it possible to check that the machine has the correct NIC(s) attached and thus on the correct subnet.
|
||
|
||
its('connected_nics') { should include /Inspec-NIC-1/ }
|
||
|
||
Note the use of the regular expression here. This is because the NIC id is a long string that contains the subscription id, resource group, machine id as well as other things. By using the regular expression the NIC can be checked without breaking this string up. It also means that other tests can be performed.
|
||
|
||
An example of the id string is `/subscriptions/1e0b427a-d58b-494e-ae4f-ee558463ebbf/resourceGroups/Inspec-Azure/providers/Microsoft.Network/networkInterfaces/Inspec-NIC-1`

This only applies to Linux machines and will always return `true` on Windows.

||
its('ssh_key_count') { should eq '0' }
|
||
|
||
### ssh\_keys
|
||
|
||
Returns an array of the keys that are assigned to the machine. This is check if the correct keys are assigned.
|
||
|
||
Most SSH public keys have a signature at the end of them that can be tested. For example:
|
||
|
||
its('ssh_keys') { should include /azure@inspec.local/ }
|
||
|
||
### boot\_diagnostics\_storage\_uri

There are a number of built in comparison operators that are available to test the result with an expected value.
|
||
|
||
For information on all that are available please refer to the [Inspec Matchers Reference](https://www.inspec.io/docs/reference/matchers/) page.
|
||
|
||
### boot\_diagnostics?
|
||
|
||
Boolean test to see if boot diagnostics have been enabled on the machine

||
|
||

|
||
|
||

||
Denotes if the machine has data disks attached to it or not.
|
||
|
||
it { should have_data_disks }
|
||
|
||
### have\_managed\_osdisk
|
||
|
||
Determine if the operating system disk is a Managed Disks or not.
|
||
|
||
This test can be used in the following way:
|
||
|
||
it { should have_managed_osdisk }
|
||
|
||
### have\_nics
|
||
|
||
Returns a boolean to state if the machine has NICs connected or not.
|
||
|
||
This has can be used in the following way:
|
||
|
||
it { should have_nics }
|
||
|
||
### have\_password\_authentication
|
||
|
||

|
||
|
||
it { should have_password_authentication }
|
||
|
||
### have\_ssh\_keys
|
||
|
||
Boolean to state if the machine has SSH keys assigned to it
|
||
|
||
it { should have_ssh_keys }
|
||
|
||
For a Windows machine this will always be false.
|
||
|
||
<br>
|
||
|
||
## Tags
|
||
|
||
It is possible to test the tags that have been assigned to the resource. There are a number of properties that can be called to check that it has tags, that it has the correct number and that the correct ones are assigned.
|
||
|
||
### have\_tags
|
||
|
||
This is a simple test to see if the machine has tags assigned to it or not.
|
||
|
||
it { should have_tags }
|
||
|
||
### tag\_count
|
||
|
||
Returns the number of tags that are assigned to the resource
|
||
|
||
its ('tag_count') { should eq 2 }
|
||
|
||
### tags
|
||
|
||
It is possible to check if a specific tag has been set on the resource.
|
||
|
||
its('tags') { should include 'Owner' }
|
||
|
||
### xxx\_tag
|
||
|
||
To get the value of the tag, a number of tests have been created from the tags that are set.
|
||
|
||
For example, if the following tag is set on a resource:
|
||
|
||
* owner: J.G. Jingleheimerschmidt
|
||
|
||
Then a test is available called `Owner_tag`.
|
||
|
||
its('owner_tag') { should cmp 'J.G. Jingleheimerschmidt' }
|
||
|
||
Note: The tag name is case sensitive which makes the test case sensitive. E.g. `owner_tag` does not equal `Owner_tag`.
