Create LXD container

# terraform init
# terraform apply -auto-approve
# terraform destroy -auto-approve
 
 
terraform {
  required_providers {
    lxd = {
      source = "terraform-lxd/lxd"
    }
  }
}
 
provider "lxd" {
  generate_client_certificates = true
  accept_remote_certificate    = true
}
 
resource "lxd_container" "lxd_container_u2004" {
  name  = "u2004"
  image = "ubuntu:20.04"
 
  config = {
    "boot.autostart" = true
  }
 
  limits = {
    cpu = 2
  }
}
 
resource "lxd_container" "lxd_container_u2110" {
  name = "u2110"
  image = "ubuntu:21.10"
  # image = "images:ubuntu-minimal:21.10" # fixme
 
  config = {
    "boot.autostart" = true
