module: azure_rm_networkinterface
version_added: "2.1"
short_description: Manage Azure network interfaces.
description:
- Create, update or delete a network interface. When creating a network interface you must provide the name of an
existing virtual network, the name of an existing subnet within the virtual network. A default security group
and public IP address will be created automatically, or you can provide the name of an existing security group
and public IP address. See the examples below for more details.
options:
resource_group:
description:
- Name of a resource group where the network interface exists or will be created.
required: true
name:
description:
- Name of the network interface.
required: true
state:
description:
- Assert the state of the network interface. Use 'present' to create or update an interface and
'absent' to delete an interface.
default: present
choices:
- absent
- present
required: false
location:
description:
- Valid azure location. Defaults to location of the resource group.
default: resource_group location
required: false
virtual_network_name:
description:
- Name of an existing virtual network with which the network interface will be associated. Required
when creating a network interface.
aliases:
- virtual_network
required: false
default: null
subnet_name:
description:
- Name of an existing subnet within the specified virtual network. Required when creating a network
interface
aliases:
- subnet
required: false
default: null
os_type:
description:
- Determines any rules to be added to a default security group. When creating a network interface, if no
security group name is provided, a default security group will be created. If the os_type is 'Windows',
a rule will be added allowing RDP access. If the os_type is 'Linux', a rule allowing SSH access will be
added.
choices:
- Windows
- Linux
default: Linux
required: false
private_ip_address:
description:
- Valid IPv4 address that falls within the specified subnet.
required: false
private_ip_allocation_method:
description:
- "Specify whether or not the assigned IP address is permanent. NOTE: when creating a network interface
specifying a value of 'Static' requires that a private_ip_address value be provided. You can update
the allocation method to 'Static' after a dynamic private ip address has been assigned."
default: Dynamic
choices:
- Dynamic
- Static
required: false
public_ip:
description:
- When creating a network interface, if no public IP address name is provided a default public IP
address will be created. Set to false, if you do not want a public IP address automatically created.
default: true
required: false
public_ip_address_name:
description:
- Name of an existing public IP address object to associate with the security group.
aliases:
- public_ip_address
- public_ip_name
required: false
default: null
public_ip_allocation_method:
description:
- If a public_ip_address_name is not provided, a default public IP address will be created. The allocation
method determines whether or not the public IP address assigned to the network interface is permanent.
choices:
- Dynamic
- Static
default: Dynamic
required: false
security_group_name:
description:
- Name of an existing security group with which to associate the network interface. If not provided, a
default security group will be created.
aliases:
- security_group
required: false
default: null
open_ports:
description:
- When a default security group is created for a Linux host a rule will be added allowing inbound TCP
connections to the default SSH port 22, and for a Windows host rules will be added allowing inbound
access to RDP ports 3389 and 5986. Override the default ports by providing a list of open ports.
type: list
required: false
default: null
tags:
description:
- "Dictionary of string:string pairs to assign as metadata to the object. Metadata tags on the object
will be updated with any provided values. To remove tags use the purge_tags option."
required: false
purge_tags:
description:
- Use to remove tags from an object. Any tags not found in the tags parameter will be removed from
the object's metadata.
default: false
required: false
