  resource "null_resource" "install_as3" {
  provisioner "local-exec" {
    command = "./install_as3.sh ${var.address} admin:${var.password} ${var.as3_rpm}"
  }
  depends_on = [null_resource.download_as3]
  }

.. code-block:: shell

  # deploy application using as3
  resource "bigip_as3" "nginx" { <----- "bigip_as3" is resource to configure as3
  as3_json    = file("example1.json")
