        - Query VM details from Azure Resource Manager
        - Requires a YAML configuration file whose name ends with 'azure_rm.(yml|yaml)'
        - By default, sets C(ansible_host) to the first public IP address found (preferring the primary NIC). If no
          public IPs are found, the first private IP (also preferring the primary NIC). The default may be overridden
          via C(hostvar_expressions); see examples.

EXAMPLES = '''
# The following host variables are always available:
# public_ipv4_addresses: all public IP addresses, with the primary IP config from the primary NIC first
# public_dns_hostnames: all public DNS hostnames, with the primary IP config from the primary NIC first
# private_ipv4_addresses: all private IP addressses, with the primary IP config from the primary NIC first
# id: the VM's Azure resource ID, eg /subscriptions/00000000-0000-0000-1111-1111aaaabb/resourceGroups/my_rg/providers/Microsoft.Compute/virtualMachines/my_vm
# location: the VM's Azure location, eg 'westus', 'eastus'
# name: the VM's resource name, eg 'myvm'
# os_profile: The VM OS properties, a dictionary, only system is currently available, eg 'os_profile.system not in ['linux']'
# powerstate: the VM's current power state, eg: 'running', 'stopped', 'deallocated'
# provisioning_state: the VM's current provisioning state, eg: 'succeeded'
# tags: dictionary of the VM's defined tag values
# resource_type: the VM's resource type, eg: 'Microsoft.Compute/virtualMachine', 'Microsoft.Compute/virtualMachineScaleSets/virtualMachines'
# vmid: the VM's internal SMBIOS ID, eg: '36bca69d-c365-4584-8c06-a62f4a1dc5d2'
# vmss: if the VM is a member of a scaleset (vmss), a dictionary including the id and name of the parent scaleset
# availability_zone: availability zone in which VM is deployed, eg '1','2','3'
#
# The following host variables are sometimes availble:
# computer_name: the Operating System's hostname. Will not be available if azure agent is not available and picking it up.


# sample 'myazuresub.azure_rm.yaml'

# required for all azure_rm inventory plugin configs
plugin: azure.azcollection.azure_rm

# forces this plugin to use a CLI auth session instead of the automatic auth source selection (eg, prevents the
# presence of 'ANSIBLE_AZURE_RM_X' environment variables from overriding CLI auth)
auth_source: cli

# fetches VMs from an explicit list of resource groups instead of default all (- '*')
include_vm_resource_groups:
- myrg1
- myrg2

# fetches VMs from VMSSs in all resource groups (defaults to no VMSS fetch)
include_vmss_resource_groups:
- '*'

# places a host in the named group if the associated condition evaluates to true
conditional_groups:
  # since this will be true for every host, every host sourced from this inventory plugin config will be in the
  # group 'all_the_hosts'
  all_the_hosts: true
  # if the VM's "name" variable contains "dbserver", it will be placed in the 'db_hosts' group
  db_hosts: "'dbserver' in name"

# adds variables to each host found by this inventory plugin, whose values are the result of the associated expression
hostvar_expressions:
  my_host_var:
  # A statically-valued expression has to be both single and double-quoted, or use escaped quotes, since the outer
  # layer of quotes will be consumed by YAML. Without the second set of quotes, it interprets 'staticvalue' as a
  # variable instead of a string literal.
  some_statically_valued_var: "'staticvalue'"
  # overrides the default ansible_host value with a custom Jinja2 expression, in this case, the first DNS hostname, or
  # if none are found, the first public IP address.
  ansible_host: (public_dns_hostnames + public_ipv4_addresses) | first

# change how inventory_hostname is generated. Each item is a jinja2 expression similar to hostvar_expressions.
hostnames:
  - tags.vm_name
  - default  # special var that uses the default hashed name

# places hosts in dynamically-created groups based on a variable value.
keyed_groups:
# places each host in a group named 'tag_(tag name)_(tag value)' for each tag on a VM.
- prefix: tag
  key: tags
# places each host in a group named 'azure_loc_(location name)', depending on the VM's location
- prefix: azure_loc
  key: location
# places host in a group named 'some_tag_X' using the value of the 'sometag' tag on a VM as X, and defaulting to the
# value 'none' (eg, the group 'some_tag_none') if the 'sometag' tag is not defined for a VM.
- prefix: some_tag
  key: tags.sometag | default('none')

# excludes a host from the inventory when any of these expressions is true, can refer to any vars defined on the host
exclude_host_filters:
# excludes hosts in the eastus region
- location in ['eastus']
- tags['tagkey'] is defined and tags['tagkey'] == 'tagkey'
- tags['tagkey2'] is defined and tags['tagkey2'] == 'tagkey2'
# excludes hosts that are powered off
- powerstate != 'running'
'''

# FUTURE: do we need a set of sane default filters, separate from the user-defineable ones?
# eg, powerstate==running, provisioning_state==succeeded
