## Synopsis

- Create and update a virtual machine scale set.

- Note that this module was called azure_rm_virtualmachine_scaleset before Ansible 2.8. The usage did not change.

Aliases: azure_rm_virtualmachine_scaleset

## 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 string |  | Active Directory username. Use when authenticating with an Active Directory user rather than service principal.
adfs_authority_url string added in 2.6 |  | Azure AD authority url. Use when authenticating with Username/password, and has your own ADFS authority.
admin_password - |  | Password for the admin username. Not required if the os_type is Linux and SSH password authentication is disabled by setting ssh_password_enabled=false.
admin_username - |  | Admin username used to access the host after it is created. Required when creating a VM.
api_profile string 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
boolean

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.

application_gateway - added in 2.8 |  | Application gateway name.

auth_source
string
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.

capacity - | Default: 1 | Capacity of VMSS.

cert_validation_mode
string
added in 2.5

Choices:
- ignore
- validate

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 string |  | Azure client ID. Use when authenticating with a Service Principal.
cloud_environment string 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.

custom_data
-
added in 2.8

Data which is made available to the virtual machine and used by e.g., `cloud-init`.
Many images in the marketplace are not cloud-init ready. Thus, data sent to custom_data would be ignored.
If the image you are attempting to use is not listed in https://docs.microsoft.com/en-us/azure/virtual-machines/linux/using-cloud-init#cloud-init-overview, follow these steps https://docs.microsoft.com/en-us/azure/virtual-machines/linux/cloudinit-prepare-custom-image.

data_disks - added in 2.4 |  | Describes list of data disks.

caching
-
added in 2.4

Choices:
- ReadOnly ←
- ReadWrite

Type of data disk caching.

| disk_size_gb - added in 2.4 |  | The initial disk size in GB for blank data disks.
| lun - added in 2.4 | Default: 0 | The logical unit number for data disk.

managed_disk_type
-
added in 2.4

Choices:
- Standard_LRS
- Premium_LRS

Managed data disk type.

enable_accelerated_networking
boolean
added in 2.7

Choices:
- no
- yes

Indicates whether user wants to allow accelerated networking for virtual machines in scaleset being created.

image
- / required

Specifies the image used to build the VM.
If a string, the image is sourced from a custom image based on the name.
If a dict with the keys publisher, offer, sku, and version, the image is sourced from a Marketplace image. Note that set version=latest to get the most recent version of a given image.
If a dict with the keys name and resource_group, the image is sourced from a custom image based on the name and resource_group set. Note that the key resource_group is optional and if omitted, all images in the subscription will be searched for by name.
Custom image support was added in Ansible 2.5.

load_balancer - added in 2.5 |  | Load balancer name.
location - |  | Valid Azure location. Defaults to location of the resource group.

managed_disk_type
-

Choices:
- Standard_LRS
- Premium_LRS

Managed disk type.

name - / required |  | Name of the virtual machine.

os_disk_caching

overprovision
boolean
added in 2.8

Choices:
- no
- yes ←

Specifies whether the Virtual Machine Scale Set should be overprovisioned.

password string |  | Active Directory user password. Use when authenticating with an Active Directory user rather than service principal.
profile string |  | Security profile found in ~/.azure/credentials file.
remove_on_absent - | Default: ["all"] | When removing a VM using state=absent, also remove associated resources. It can be `all` or a list with any of the following ['network_interfaces', 'virtual_storage', 'public_ips']. Any other input will be ignored.

It can be a dict which contains name and resource_group of the security group. aliases: security_group_name
short_hostname - |  | Short host name.

single_placement_group
boolean
added in 2.9

Choices:
- no
- yes ←

When true this limits the scale set to a single placement group, of max size 100 virtual machines.

ssh_password_enabled
boolean

Choices:
- no
- yes ←

When the os_type is Linux, setting ssh_password_enabled=false will disable SSH password authentication and require use of SSH keys.

ssh_public_keys - |  | For os_type=Linux provide a list of SSH keys. Each item in the list should be a dictionary where the dictionary contains two keys, `path` and `key_data`. Set the `path` to the default location of the authorized_keys files. On an Enterprise Linux host, for example, the path=/home/<admin username>/.ssh/authorized_keys. Set `key_data` to the actual value of the public key.

state
-

Choices:
- absent

Assert the state of the virtual machine scale set.

State `absent` will remove the virtual machine scale set.

subnet_name - |  | Subnet name. aliases: subnet
subscription_id string |  | Your Azure subscription Id.
tags dictionary |  | 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.

vm_size - |  | A valid Azure VM size value. For example, `Standard_D4`. The list of choices varies depending on the subscription and location. Check your subscription for available choices.
zones list added in 2.8 |  | A list of Availability Zones for your virtual machine scale set.

## Notes

Note

- For authentication with Azure you can pass parameters, set environment variables, use a profile stored in ~/.azure/credentials, or log in before you run your tasks or playbook with `az login`.

- Authentication is also 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.
