Terraform "Hello, World" example

This folder contains a "Hello, World" example of a Terraform file on Google Cloud Platform (GCP).

This Terraform file deploys a single server on Google Cloud Platform (GCP) using the shortest script.

You must have Terraform installed on your computer.
You must have a Google Cloud Platform (GCP) account.
You must have downloaded a Google Cloud Platform credentials file.
You must have enabled the Google Compute Engine API.
It uses the Terraform Google Cloud Provider that interacts with the many resources supported by Google Cloud Platform (GCP) through its APIs.
This code was written for Terraform 0.10.x.

Configure your Google Cloud access keys.

Two ways in order to configure credentials:
- Configure GOOGLE_APPLICATION_CREDENTIALS environment variable. The variable must contain the path to the credentials file.
  
  To set these variable on Linux, macOS, or Unix, use export:
```
export GOOGLE_APPLICATION_CREDENTIALS="~/.gcloud/terraform-examples-code.json"
```
  To set these variable on Windows, use set:
```
set GOOGLE_APPLICATION_CREDENTIALS="C:\Users\USERNAME\.gcloud\terraform-examples-code.json"
```
- Configure GOOGLE_CREDENTIALS environment variable. The variable must contain the content of the credentials file and not the path to it.
  
  To set these variable on Linux, macOS, or Unix, use export:
```
export GOOGLE_CREDENTIALS="$(cat ~/.gcloud/terraform-examples-code.json)"
```
Initialize working directory.

The first command that should be run after writing a new Terraform configuration is the terraform init command in order to initialize a working directory containing Terraform configuration files. It is safe to run this command multiple times.
```
terraform init
```
Validate the changes.

Run command:
```
terraform plan
```
Deploy the changes.

Run command:
```
terraform apply
```
Test the deploy.

When the terraform apply command completes, use the Google Cloud console, you should see the new Google Compute instance.
Clean up the resources created.

When you have finished, run command:
```
terraform destroy
```
