Description

I'd like to manage elastic pools in Azure DevOps. This means using terraform to apply and destroy pools linked to Azure VM Scale Sets.

New or Affected Resource(s)

• azuredevops_agent_elasticpool

Potential Terraform Configuration

resource "azuredevops_agent_elasticpool" "pool" {
  name                = "sample-elasticpool"
  auto_provision  = false
  desired_idle      = 1
  max_capacity    = 3
  maxSavedNodeCount = 0
  serviceendpoint_azurem_id = azuredevops_serviceendpoint_azurerm.azure.id
  vmss_id             = "/subscriptions/..../..."
   ....
}

Hi @Ravio1i,

Please vote on my #204 feature request, since this request seems to be about the same thing. 🙂 Also, there's some additional information inside of it that might be of interest for you.

I accidentally filed a duplicate on this one. In it I proposed a change to the existing azuredevops_agent_pool instead of a new resource.

resource "azuredevops_agent_pool" "pool" {
  name                   = "scalesetpool"
  description            = "Scale set agent pool"
  pool_type              = "scaleset"
  scaleset_configuration = {
    service_connection_id      = azuredevops_serviceendpoint_azurerm.endpoint.id
    azure_scaleset_name        = "vmss"
    automatically_tear_down    = true
    max_agents                 = 10
    min_agents                 = 2
    delete_excess_agents_delay = 30
  }
}

I'm not precious about it and I also like the idea of a new resource. I'm just adding this into the mix so anyone implementing it has multiple ideas to pull from. I'm just keen to have the ability to control the VMSS agent pools with Terraform regardless of how it ends up.
