:platform: linux

:configuration: This module requires Azure Resource Manager credentials to be passed as a dictionary of
    keyword arguments to the ``connection_auth`` parameter in order to work properly. Since the authentication
    parameters are sensitive, it's recommended to pass them to the states via pillar.

    Required provider parameters:

    if using username and password:
      * ``subscription_id``
      * ``username``
      * ``password``

    if using a service principal:
      * ``subscription_id``
      * ``tenant``
      * ``client_id``
      * ``secret``

    Optional provider parameters:

    **cloud_environment**: Used to point the cloud driver to different API endpoints, such as Azure GovCloud. Possible values:
      * ``AZURE_PUBLIC_CLOUD`` (default)
      * ``AZURE_CHINA_CLOUD``
      * ``AZURE_US_GOV_CLOUD``
      * ``AZURE_GERMAN_CLOUD``

    Example Pillar for Azure Resource Manager authentication:

    .. code-block:: yaml

        azurearm:
            user_pass_auth:
                subscription_id: 3287abc8-f98a-c678-3bde-326766fd3617
                username: fletch
                password: 123pass
            mysubscription:
                subscription_id: 3287abc8-f98a-c678-3bde-326766fd3617
                tenant: ABCDEFAB-1234-ABCD-1234-ABCDEFABCDEF
                client_id: ABCDEFAB-1234-ABCD-1234-ABCDEFABCDEF
                secret: XXXXXXXXXXXXXXXXXXXXXXXX
                cloud_environment: AZURE_PUBLIC_CLOUD

    Ensure a load balancer exists.

    :param name:
        Name of the load balancer.

    :param resource_group:
        The resource group assigned to the load balancer.

    :param sku:
        The load balancer SKU, which can be 'Basic' or 'Standard'.

    :param tags:
        A dictionary of strings can be passed as tag metadata to the load balancer object.

    :param frontend_ip_configurations:
        An optional list of dictionaries representing valid FrontendIPConfiguration objects. A frontend IP
        configuration can be either private (using private IP address and subnet parameters) or public (using a
        reference to a public IP address object). Valid parameters are:

        - ``name``: The name of the resource that is unique within a resource group.
        - ``private_ip_address``: The private IP address of the IP configuration. Required if
          'private_ip_allocation_method' is 'Static'.
        - ``private_ip_allocation_method``: The Private IP allocation method. Possible values are: 'Static' and
          'Dynamic'.
        - ``subnet``: Name of an existing subnet inside of which the frontend IP will reside.
        - ``public_ip_address``: Name of an existing public IP address which will be assigned to the frontend IP object.

    :param backend_address_pools:
        An optional list of dictionaries representing valid BackendAddressPool objects. Only the 'name' parameter is
        valid for a BackendAddressPool dictionary. All other parameters are read-only references from other objects
        linking to the backend address pool. Inbound traffic is randomly load balanced across IPs in the backend IPs.

    :param probes:
        An optional list of dictionaries representing valid Probe objects. Valid parameters are:

        - ``name``: The name of the resource that is unique within a resource group.
        - ``protocol``: The protocol of the endpoint. Possible values are 'Http' or 'Tcp'. If 'Tcp' is specified, a
          received ACK is required for the probe to be successful. If 'Http' is specified, a 200 OK response from the
          specified URI is required for the probe to be successful.
        - ``port``: The port for communicating the probe. Possible values range from 1 to 65535, inclusive.
        - ``interval_in_seconds``: The interval, in seconds, for how frequently to probe the endpoint for health status.
          Typically, the interval is slightly less than half the allocated timeout period (in seconds) which allows two
          full probes before taking the instance out of rotation. The default value is 15, the minimum value is 5.
        - ``number_of_probes``: The number of probes where if no response, will result in stopping further traffic from
          being delivered to the endpoint. This values allows endpoints to be taken out of rotation faster or slower
          than the typical times used in Azure.
        - ``request_path``: The URI used for requesting health status from the VM. Path is required if a protocol is
          set to 'Http'. Otherwise, it is not allowed. There is no default value.

    :param load_balancing_rules:
        An optional list of dictionaries representing valid LoadBalancingRule objects. Valid parameters are:

        - ``name``: The name of the resource that is unique within a resource group.
        - ``load_distribution``: The load distribution policy for this rule. Possible values are 'Default', 'SourceIP',
          and 'SourceIPProtocol'.
        - ``frontend_port``: The port for the external endpoint. Port numbers for each rule must be unique within the
          Load Balancer. Acceptable values are between 0 and 65534. Note that value 0 enables 'Any Port'.
        - ``backend_port``: The port used for internal connections on the endpoint. Acceptable values are between 0 and
          65535. Note that value 0 enables 'Any Port'.
        - ``idle_timeout_in_minutes``: The timeout for the TCP idle connection. The value can be set between 4 and 30
          minutes. The default value is 4 minutes. This element is only used when the protocol is set to TCP.
        - ``enable_floating_ip``: Configures a virtual machine's endpoint for the floating IP capability required
          to configure a SQL AlwaysOn Availability Group. This setting is required when using the SQL AlwaysOn
          Availability Groups in SQL server. This setting can't be changed after you create the endpoint.
        - ``disable_outbound_snat``: Configures SNAT for the VMs in the backend pool to use the public IP address
          specified in the frontend of the load balancing rule.
        - ``frontend_ip_configuration``: Name of the frontend IP configuration object used by the load balancing rule
          object.
        - ``backend_address_pool``: Name of the backend address pool object used by the load balancing rule object.
          Inbound traffic is randomly load balanced across IPs in the backend IPs.
        - ``probe``: Name of the probe object used by the load balancing rule object.

    :param inbound_nat_rules:
        An optional list of dictionaries representing valid InboundNatRule objects. Defining inbound NAT rules on your
        load balancer is mutually exclusive with defining an inbound NAT pool. Inbound NAT pools are referenced from
        virtual machine scale sets. NICs that are associated with individual virtual machines cannot reference an
        Inbound NAT pool. They have to reference individual inbound NAT rules. Valid parameters are:

        - ``name``: The name of the resource that is unique within a resource group.
        - ``frontend_ip_configuration``: Name of the frontend IP configuration object used by the inbound NAT rule
          object.
        - ``protocol``: Possible values include 'Udp', 'Tcp', or 'All'.
        - ``frontend_port``: The port for the external endpoint. Port numbers for each rule must be unique within the
          Load Balancer. Acceptable values range from 1 to 65534.
        - ``backend_port``: The port used for the internal endpoint. Acceptable values range from 1 to 65535.
        - ``idle_timeout_in_minutes``: The timeout for the TCP idle connection. The value can be set between 4 and 30
          minutes. The default value is 4 minutes. This element is only used when the protocol is set to TCP.
        - ``enable_floating_ip``: Configures a virtual machine's endpoint for the floating IP capability required
          to configure a SQL AlwaysOn Availability Group. This setting is required when using the SQL AlwaysOn
          Availability Groups in SQL server. This setting can't be changed after you create the endpoint.

    :param inbound_nat_pools:
        An optional list of dictionaries representing valid InboundNatPool objects. They define an external port range
        for inbound NAT to a single backend port on NICs associated with a load balancer. Inbound NAT rules are created
        automatically for each NIC associated with the Load Balancer using an external port from this range. Defining an
        Inbound NAT pool on your Load Balancer is mutually exclusive with defining inbound NAT rules. Inbound NAT pools
        are referenced from virtual machine scale sets. NICs that are associated with individual virtual machines cannot
        reference an inbound NAT pool. They have to reference individual inbound NAT rules. Valid parameters are:

        - ``name``: The name of the resource that is unique within a resource group.
        - ``frontend_ip_configuration``: Name of the frontend IP configuration object used by the inbound NAT pool
          object.
        - ``protocol``: Possible values include 'Udp', 'Tcp', or 'All'.
        - ``frontend_port_range_start``: The first port number in the range of external ports that will be used to
          provide Inbound NAT to NICs associated with a load balancer. Acceptable values range between 1 and 65534.
        - ``frontend_port_range_end``: The last port number in the range of external ports that will be used to
          provide Inbound NAT to NICs associated with a load balancer. Acceptable values range between 1 and 65535.
        - ``backend_port``: The port used for internal connections to the endpoint. Acceptable values are between 1 and
          65535.

    :param outbound_nat_rules:
        An optional list of dictionaries representing valid OutboundNatRule objects. Valid parameters are:

        - ``name``: The name of the resource that is unique within a resource group.
        - ``frontend_ip_configuration``: Name of the frontend IP configuration object used by the outbound NAT rule
          object.
        - ``backend_address_pool``: Name of the backend address pool object used by the outbound NAT rule object.
          Outbound traffic is randomly load balanced across IPs in the backend IPs.
        - ``allocated_outbound_ports``: The number of outbound ports to be used for NAT.

    :param connection_auth:
        A dict with subscription and authentication parameters to be used in connecting to the
        Azure Resource Manager API.

    Example usage:
