# s3

Stores the state as a given key in a given bucket on [Amazon S3](https://aws.amazon.com/s3/).

-> **Note:** Passing credentials directly via config options will
make them included in cleartext inside the persisted state.
Use of environment variables or config file is recommended.

## Example Usage

```
terraform remote config \
	-backend=s3 \
	-backend-config="bucket=terraform-state-prod" \
	-backend-config="key=network/terraform.tfstate" \
	-backend-config="region=us-east-1"
```

## Example Referencing

```
resource "terraform_remote_state" "foo" {
	backend = "s3"
	config {
		bucket = "terraform-state-prod"
		key = "network/terraform.tfstate"
		region = "us-east-1"
	}
}
```

## Configuration variables

The following configuration options / environment variables are supported:

 * `bucket` - (Required) The name of the S3 bucket
 * `key` - (Required) The path where to place/look for state file inside the bucket
 * `region` / `AWS_DEFAULT_REGION` - (Optional) The region of the S3 bucket
