Explanation
The prefix -/+ means that Terraform will destroy and recreate the resource, rather than updating it in-place.
The prefix ~ means that some attributes and resources can be updated in-place.
$ terraform apply
aws_instance.example: Refreshing state... [id=i-0bbf06244e44211d1]
An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
-/+ destroy and then create replacement
Terraform will perform the following actions:
