# Example Configurations
|
|
|
|
These examples are designed to help you understand some
|
|
of the ways Terraform can be used.
|
|
|
|
All examples are ready to run as-is. Terraform will
|
|
ask for input of things such as variables and API keys. If you want to
|
|
conitnue using the example, you should save those parameters in a
|
|
"terraform.tfvars" file or in a `provider` config bock.
|
|
|
|
<div class="alert alert-block alert-warning">
|
|
<div>
|
|
<strong>Note:</strong> The examples use real providers that launch
|
|
<em>real</em> resources. That means they can cost money to
|
|
experiment with. To avoid unexpected charges, be sure to understand the price
|
|
of resources before launching them, and verify any unneeded resources
|
|
are cleaned up afterwards.</div>
|
|
</div>
|
|
|
|
Experimenting in this way can help you learn how the Terraform lifecycle
|
|
works, as well as how to repeatedly create and destroy infrastructure.
|
|
|
|
If you're completely new to Terraform, we recommend reading the
|
|
[getting started guide](/intro/getting-started/install.html) before diving into
|
|
the examples. However, due to the intuitive configuration Terraform
|
|
uses it isn't required.
|
|
|
|
## Examples
|
|
|
|
All of the examples are in the
|
|
["examples" directory within the Terraform source code](https://github.com/hashicorp/terraform/tree/master/examples). Each example (as well as the examples
|
|
directory) has a README explaining the goal of the example.
|
|
|
|
To use these examples, Terraform must first be installed on your machine.
|
|
You can install Terraform from the [downloads page](/downloads.html).
|
|
Once installed, you can use two steps to view and run the examples.
|
|
|
|
To clone any examples, run `terraform init` with the URL to the example:
|
|
|
|
```
|
|
$ terraform init github.com/hashicorp/terraform/examples/aws-two-tier
|
|
...
|
|
```
|
|
|
|
This will put the example files within your working directory. You can then
|
|
use your own editor to read and browse the configurations. This command will
|
|
not _run_ any code.
|
|
|
|
If you want to run the example, just run `terraform apply`:
|
|
|
|
```
|
|
$ terraform apply
|
|
...
|
|
```
|
|
|
|
Terraform will interactively ask for variable input and potentially
|
|
provider configuration, and will start executing.
|
|
|
|
When you're done with the example, run `terraform destroy` to clean up.
