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:
    ~ update in-place
-/+ destroy and then create replacement
    <= read (data resources)

Terraform will perform the following actions:
