Changes to Outputs.

Changes to Outputs:
+   file = <<-EOT
        |------------------|
        | I am an artifact |

Terraform plan in tests/terraform/s3
With backend config: bucket=tf-state-911453050078 key=sandbox1.tfstate workspace_key_prefix=github-workflows
With var files: tests/terraform/s3/environment/sandbox.tfvars

Plan: 2 to add, 0 to change, 0 to destroy. Changes to Outputs.

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
+   create

Terraform will perform the following actions:

  # random_id.this will be created
+   resource "random_id" "this" {
+       b64_std     = (known after apply)
+       b64_url     = (known after apply)
+       byte_length = 4
+       dec         = (known after apply)
+       hex         = (known after apply)
+       id          = (known after apply)
    }

  # random_pet.this will be created
+   resource "random_pet" "this" {
+       id        = (known after apply)
+       length    = 2
+       separator = "-"
    }

Plan: 2 to add, 0 to change, 0 to destroy.

Changes to Outputs:
+   random_id  = (known after apply)
+   random_pet = (known after apply)
