preview terraform actions

The terraform plan command creates an execution plan, which lets you preview the changes that Terraform plans to make to your infrastructure. By default, when Terraform creates a plan it:

• Reads the current state of any already-existing remote objects to make sure that the Terraform state is up-to-date.

• Compares the current configuration to the prior state and noting any differences.

• Proposes a set of change actions that should, if applied, make the remote objects match the configuration.
