-Partner and community providers are signed by their developers.
-If you'd like to know more about provider signing, you can read about it here:
-https://www.terraform.io/docs/cli/plugins/signing.html
-Terraform has created a lock file .terraform.lock.hcl to record the provider
-selections it made above. Include this file in your version control repository
-so that Terraform can guarantee to make the same selections by default when
-you run "terraform init" in the future.
-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.
