An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  - destroy
 
Terraform will perform the following actions:
 
  - aws_instance.ubuntu-server
 
  - aws_security_group.allow-all
 
  - aws_subnet.a
 
  - aws_subnet.c
 
  - aws_vpc.test
 
 
Plan: 0 to add, 0 to change, 5 to destroy.
 
Do you really want to destroy all resources?
  Terraform will destroy all your managed infrastructure, as shown above.
  There is no undo. Only 'yes' will be accepted to confirm.
