		Set `INFRACOST_CURRENCY` variable to set currency [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217#Active_codes) prices should be converted to. Defaults to USD.

		## Variants

		The Terraform template can be used in conjunction with template variants to cover specific cases.

		### Vault variant

		This variant allows delegating your secrets management to a [Vault](https://www.vaultproject.io/) server.

		#### Configuration

		In order to be able to communicate with the Vault server, the variant requires the additional configuration parameters:

		\| Name \| description \| default value \|
		\| ----------------- \| -------------------------------------- \| ----------------- \|
		\| `VAULT_BASE_URL` \| The Vault server base API url \| _none_ \|
		\| :lock: `VAULT_ROLE_ID` \| The [AppRole](https://www.vaultproject.io/docs/auth/approle) RoleID \| must be defined \|
		\| :lock: `VAULT_SECRET_ID` \| The [AppRole](https://www.vaultproject.io/docs/auth/approle) SecretID \| must be defined \|

		#### Usage

		Then you may retrieve any of your secret(s) from Vault using the following syntax:

		```text
		@url@http://vault-secrets-provider/api/secrets/{secret_path}?field={field}
		```

		With:

		\| Name \| description \|
		\| -------------------------------- \| -------------------------------------- \|
		\| `secret_path` (_path parameter_) \| this is your secret location in the Vault server \|
		\| `field` (_query parameter_) \| parameter to access a single basic field from the secret JSON payload \|

		#### Example

		```yaml
		include:
		# main template
		- project: 'to-be-continuous/terraform'
		ref: '2.3.2'
		file: '/templates/gitlab-ci-terraform.yml'
		# Vault variant
		- project: 'to-be-continuous/terraform'
		ref: '2.3.2'
		file: '/templates/gitlab-ci-terraform-vault.yml'

		variables:
		# Secrets managed by Vault
		AWS_ACCESS_KEY_ID: "@url@http://vault-secrets-provider/api/secrets/b7ecb6ebabc231/aws/prod/account?field=access_key_id"
		AWS_SECRET_ACCESS_KEY: "@url@http://vault-secrets-provider/api/secrets/b7ecb6ebabc231/aws/prod/account?field=secret_access_key"
		VAULT_BASE_URL: "https://vault.acme.host/v1"
		# $VAULT_ROLE_ID and $VAULT_SECRET_ID defined as a secret CI/CD variable
		```

		## GitLab compatibility

		:information_source: This template is actually tested and validated on GitLab Community Edition instance version 13.12.11
