| Due to the renaming of Company, the Github organization has changed name from "amestofortytwo" to "fortytwoservices". Pre-existing Terraform code would need to change that in code. |
This module deploys a virtual machine scale set for self hosted runners for Azure DevOps and GitHub.

module "vmss" {
source = "fortytwoservices/selfhostedrunnervmss/azurerm"

}After deploying the virtual machine scale set, you need to configure the Azure DevOps or GitHub side of things according to our documentation:
The following requirements are needed by this module:
terraform {
required_version = ">=1.4.6"

azurerm = {
source = "hashicorp/azurerm"
version = ">=3.100.0"
}

operating_system = "ubuntu" # windows or ubuntu

The following resources are used by this module:
No required inputs.
The following input variables are optional (have default values):

Type: string
Default: "Standard_D2s_v3"
Description: n/a
Type: list(string)
