Description

It would be nice to have data sources for the following elements:

• Instance server details like RAM, CPU, GPU provided by scw instance server-type list -o json
• Available ami available on the account with filtering by tags

New or Affected Resource(s)

• scaleway_instance_server_types
• scaleway_instance_image

Potential Terraform Configuration

data scaleway_instance_image myapp {
  tags   = ["production","myapp"]
  latest = true
}

data scaleway_instance_server_types all{
}

locals {
   allowed_app_ram = data.scaleway_instance_server_types.all[var.app_server_type]-100000000 
   cloud-init = templatefile("cloud-init.yaml.tpl",{app_ram= local.allowed_app_ram})
}

resource "scaleway_instance_server" "web" {
  type = var.app_server_type
  image = data.scaleway_instance_image.myapp.id
  user_data = {
    cloud-init = local.cloud-init
  }
}
