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:

  # consul_key_prefix.foo must be replaced
-/+ resource "consul_key_prefix" "foo" {
      ~ datacenter  = "dc1" -> (known after apply)
      ~ id          = "foo/" -> (known after apply)
      + path_prefix = "foo/" # forces replacement
        subkeys     = {
            "bar" = "Bar"
            "baz" = "Baz"
        }
    }

Plan: 1 to add, 0 to change, 1 to destroy.
