  Terraform has been successfully initialized! 
  You may now begin working with Terraform. Try running "terraform plan" to see 
  any changes that are required for your infrastructure. All Terraform commands 
  should now work. 
  If you ever set or change modules or backend configuration for Terraform, 
  rerun this command to reinitialize your working directory. If you forget, other 
  commands will detect it and remind you to do so if necessary. 
  
  3. Create an execution plan: 
  
  **terraform plan**
  Refreshing Terraform state in-memory prior to plan...

  Output truncated 
  ... 
  Plan: 33 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.
