  • outputs.tf : This contains output from the resources.
  • provider.tf : It contains provider definition.

Example : Using Local provider, create a file nix.txt.

$ mkdir iac01 && cd iac01
$ vi main.tf
resource "local_file" "distros" {
  filename = "/tmp/nix.txt"
  content = "I Love Linux distros like Ubuntu. Debian, RHEL, Rocky Linux & Kali Linux etc"
}

Save and close the file

Next initialize the terraform, plan and apply.

$ terraform init
