azure_rm_subnet - Manage Azure subnets.

New in version 2.1.

Synopsis

  • Create, update or delete a subnet within a given virtual network. Allows setting and updating the address prefix CIDR, which must be valid within the context of the virtual network. Use the azure_rm_networkinterface module to associate interfaces with the subnet and assign specific IP addresses.

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 2.7
  • azure >= 2.0.0

Parameters

Parameter Choices/Defaults Comments
ad_user
Active Directory username. Use when authenticating with an Active Directory user rather than service principal.
address_prefix_cidr
required
CIDR defining the IPv4 address space of the subnet. Must be valid within the context of the virtual network.

aliases: address_prefix
adfs_authority_url
(added in 2.6)
Default:
None
Azure AD authority url. Use when authenticating with Username/password, and has your own ADFS authority.
api_profile
(added in 2.5)
Default:
latest
Selects an API profile to use when communicating with Azure services. Default value of latest is appropriate for public clouds; future values will allow use with Azure Stack.
append_tags
bool
    Choices:
  • no
  • yes ←
Use to control if tags field is canonical or just appends to existing tags. When canonical, any tags not found in the tags parameter will be removed from the object's metadata.
auth_source
(added in 2.5)
    Choices:
  • auto
  • cli
  • credential_file
  • env
  • msi
Controls the source of the credentials to use for authentication.
If not specified, ANSIBLE_AZURE_AUTH_SOURCE environment variable will be used and default to auto if variable is not defined.
auto will follow the default precedence of module parameters -> environment variables -> default profile in credential file ~/.azure/credentials.
When set to cli, the credentials will be sources from the default Azure CLI profile.
Can also be set via the ANSIBLE_AZURE_AUTH_SOURCE environment variable.
When set to msi, the host machine must be an azure resource with an enabled MSI extension. subscription_id or the environment variable AZURE_SUBSCRIPTION_ID can be used to identify the subscription ID if the resource is granted access to more than one subscription, otherwise the first subscription is chosen.
The msi was added in Ansible 2.6.
cert_validation_mode
(added in 2.5)
    Choices:
  • validate
  • ignore
Controls the certificate validation behavior for Azure endpoints. By default, all modules will validate the server certificate, but when an HTTPS proxy is in use, or against Azure Stack, it may be necessary to disable this behavior by passing ignore. Can also be set via credential file profile or the AZURE_CERT_VALIDATION environment variable.
client_id
Azure client ID. Use when authenticating with a Service Principal.
cloud_environment
(added in 2.4)
Default:
AzureCloud
For cloud environments other than the US public cloud, the environment name (as defined by Azure Python SDK, eg, AzureChinaCloud, AzureUSGovernment), or a metadata discovery endpoint URL (required for Azure Stack). Can also be set via credential file profile or the AZURE_CLOUD_ENVIRONMENT environment variable.
name
required
Name of the subnet.
password
Active Directory user password. Use when authenticating with an Active Directory user rather than service principal.
profile
Security profile found in ~/.azure/credentials file.
resource_group
required
Name of resource group.
route_table
(added in 2.7)
The reference of the RouteTable resource.
It can accept both a str or a dict.
The str can be the name or resource id of the route table.
The dict can contains name and resource_group of the route_table.
secret
Azure client secret. Use when authenticating with a Service Principal.
security_group
Existing security group with which to associate the subnet.
It can be the security group name which is in the same resource group.
It can be the resource Id.
It can be a dict which contains name and resource_group of the security group.

aliases: security_group_name
state
    Choices:
  • absent
  • present ←
Assert the state of the subnet. Use 'present' to create or update a subnet and 'absent' to delete a subnet.
subscription_id
Your Azure subscription Id.
tags
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 set append_tags option to false.
tenant
Azure tenant ID. Use when authenticating with a Service Principal.
virtual_network_name
required
Name of an existing virtual network with which the subnet is or will be associated.

aliases: virtual_network

Notes

Note

  • For authentication with Azure you can pass parameters, set environment variables or use a profile stored in ~/.azure/credentials. Authentication is possible using a service principal or Active Directory user. To authenticate via service principal, pass subscription_id, client_id, secret and tenant or set environment variables AZURE_SUBSCRIPTION_ID, AZURE_CLIENT_ID, AZURE_SECRET and AZURE_TENANT.
  • To authenticate via Active Directory user, pass ad_user and password, or set AZURE_AD_USER and AZURE_PASSWORD in the environment.
  • Alternatively, credentials can be stored in ~/.azure/credentials. This is an ini file containing a [default] section and the following keys: subscription_id, client_id, secret and tenant or subscription_id, ad_user and password. It is also possible to add additional profiles. Specify the profile by passing profile or setting AZURE_PROFILE in the environment.
