Initializing the backend... Initializing provider plugins... - Checking for available provider plugins... - Downloading plugin for provider "aws" (hashicorp/aws) 2.18.0... 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 moduls 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.
