Terraform Commands #9
=====================
- How to Check Terraform Version

.. code-block:: shell
  
  terraform version
  Terraform v0.12.20
  + provider.bigip v1.1.1
  + provider.null v2.1.2

When we do "terraform version" it list out terraform version being used which 0.12.20, 
It also provides information of BIG-IP Terraform Provider Version which v1.1.1


.. code-block:: shell

 terraform plan
 Refreshing Terraform state in-memory prior to plan...
 The refreshed state will be used to calculate this plan, but will not be
 persisted to local or remote state storage.


 ------------------------------------------------------------------------

 An execution plan has been generated and is shown below.
 Resource actions are indicated with the following symbols:
  + create

 Terraform will perform the following actions:

  # bigip_as3.nginx will be created
  + resource "bigip_as3" "nginx" {
      + as3_json    = jsonencode(
            {

    }

  # null_resource.install_as3 will be created
  + resource "null_resource" "install_as3" {
      + id = (known after apply)
    }

  Plan: 3 to add, 0 to change, 0 to destroy.

  ------------------------------------------------------------------------

  Note: You didn't specify an "-out" parameter to save this plan, so Terraform
  can't guarantee that exactly these actions will be performed if
  "terraform apply" is subsequently run.
 
  terraform validate
  Success! The configuration is valid.
