# Example Configurations
|
|
|
|
The examples in this section illustrate 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
|
|
continue using the example, you should save those parameters in a
|
|
"terraform.tfvars" file or in a `provider` config block.
|
|
|
|
~> **Warning!** The examples use real providers that launch _real_ 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.
|
|
|
|
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
|
|
[Terraform: Get Started](https://learn.hashicorp.com/collections/terraform/aws-get-started?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS) collection on HashiCorp Learn before diving into
|
|
the examples. However, due to the intuitive configuration Terraform
|
|
uses it isn't required.
|
|
|
|
## Examples
|
|
|
|
Our examples are distributed across several repos. [This README file in the Terraform repo has links to all of them.](https://github.com/hashicorp/terraform/tree/master/examples)
|
|
|
|
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 download, view, and run the examples.
|
|
|
|
To use an example, clone the repository that contains it and navigate to its directory. For example, to try the AWS two-tier architecture example:
|
|
|
|
```
|
|
git clone https://github.com/terraform-providers/terraform-provider-aws.git
|
|
cd terraform-provider-aws/examples/two-tier
|
|
```
|
|
|
|
You can then use your preferred code editor to browse and read the configurations.
|
|
To try out an example, run Terraform's init and apply commands while in the example's directory:
|
|
|
|
```
|
|
$ terraform init
|
|
...
|
|
$ 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.
