Initializing provider plugins...

The following providers do not have any version constraints in configuration,

so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking

changes, it is recommended to add version = "..." constraints to the

corresponding provider blocks in configuration, with the constraint strings

suggested below.

* provider.local: version = "~> 1.2"

* provider.template: version = "~> 2.1"

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see

any changes that are required for your infrastructure. All Terraform commands

should now work.

If you ever set or change modules or backend configuration for Terraform,

rerun this command to reinitialize your working directory. If you forget, other

commands will detect it and remind you to do so if necessary.

terraform plan

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.

data.template_file.init: Refreshing state...

local_file.foo: Refreshing state... (ID: bf52295095341d2d11821cecc698720af3a7d98f)

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:

-/+ local_file.foo (new resource required)

      id: "bf52295095341d2d11821cecc698720af3a7d98f" => <computed> (forces new resource)

Note: You didn't specify an "-out" parameter to save this plan, so Terraform

can't guarantee that exactly these actions will be performed if

"terraform apply" is subsequently run.
