     9  # Template Provider
    10  
    11  The template provider exposes resources to use templates to generate
    12  strings for other Terraform resources or outputs.
    13  
    14  The template provider is what we call a _logical provider_. This has no
    15  impact on how it behaves, but conceptually it is important to understand.
    16  The template provider doesn't manage any _physical_ resources; it isn't
    17  creating servers, writing files, etc. It is used to generate attributes that
    18  can be used for interpolation for other resources. Examples will explain
    19  this best.
    20  
    21  Use the navigation to the left to read about the available resources.
    22  
    23  ## Example Usage
    24  
    25  ```
    26  # Template for initial configuration bash script
    27  resource "template_file" "init" {
    28  	filename = "init.tpl"
    29  
    30  	vars {
    31  		consul_address = "${aws_instance.consul.private_ip}"
    32  	}
    33  }
    34  
    35  # Create a web server
    36  resource "aws_instance" "web" {
    37      # ...
    38  
    39  	user_data = "${template_file.init.rendered}"
    40  }
    41  ```
