Limit workspace CPU and memory resources
Configuration Coder v2.19.0 self hosted, Terraform 1.9.8, DinD with Sysbox current main.tf Does not limit cpu, does not impose a hard limit, but adjusts the priority of the container relative to others. 
resource "docker_container" "workspace" {
  #
  memory     = 2048          # Memory limit at 2048 MB (2 GB)
  cpu_shares = 1024          # Default CPU weight
  #
}
resource "docker_container" "workspace" {
  #
  memory     = 2048          # Memory limit at 2048 MB (2 GB)
  cpu_shares = 1024          # Default CPU weight
  #
}
main.tf desired, but in error 
resource "docker_container" "workspace" {
  #
  resources {
    limits {
      memory = "512m"      # Memory limit at 512 MB
      cpu    = 1           # CPU limit at 1 unit (equivalent to one CPU core)
    }
    reservations {
      memory = "256m"      # Memory reservation at 256 MB
      cpu    = 0.5         # CPU reservation at 0.5 units
    }
  }
  #
}
resource "docker_container" "workspace" {
  #
  resources {
    limits {
      memory = "512m"      # Memory limit at 512 MB
      cpu    = 1           # CPU limit at 1 unit (equivalent to one CPU core)
    }
    reservations {
      memory = "256m"      # Memory reservation at 256 MB
      cpu    = 0.5         # CPU reservation at 0.5 units
    }
  }
  #
}

Question Does anyone know how to limit the CPU and memory resources of workspaces with Terraform? THANKS a lot.
