# terraform-secrets-helper

[![Release][release-badge]][latest-release]

💡 Learn more about Masterpoint [below](#who-we-are-𐦂𖨆𐀪𖠋).

## Purpose and Functionality

This Terraform module provides a standard and extensible way of managing secrets from different sources, making them accessible through `local.secrets[""]`. It's designed to create an abstract interface for dealing with secrets in Terraform, regardless of the source of these secrets.

Our initial version is built to handle [SOPS secrets](https://github.com/getsops/sops), but it is designed in a way that it can be easily extended to support other secret providers like AWS SSM Parameter Store, Vault, and more in the future.

This module can be included as a child module, where needed, to fetch secrets and provide them in an abstract manner.

## Usage

Copy `exports/secrets.mixin.tf` to your project by running the following command:

```sh

curl -sL https://raw.githubusercontent.com/masterpointio/terraform-secrets-helper/main/exports/secrets.mixin.tf -o secrets.mixin.tf

```

The mixin incorporates the invocation of this module, so you simply need to configure the required `secret_mapping` variable and then reference it within your code.

See the full example in [examples/complete](https://github.com/masterpointio/terraform-secrets-helper/tree/main/examples/complete)

### SOPS Secrets

```hcl

secret_mapping = [{

  name = "db_password"

  file = "test.yaml"

  type = "sops"

}]

output "db_password" {

  value     = jsonencode(local.secrets["db_password"])

  sensitive = true

}

```

### AWS SSM Parameter Store Secrets

```hcl

secret_mapping = [{

  name = "api_token"

  type = "ssm"

  path = "/myapp/prod/api_token"

}]

```

### Mixed Sources

You can combine both SOPS and SSM secrets in the same configuration:

```hcl

secret_mapping = [

  {

    name = "db_password"

    type = "sops"

    file = "secrets.yaml"

  },

  {

    name = "api_token"

    type = "ssm"

    path = "/myapp/prod/api_token"

  }

]

```

# Future Enhancements

The module currently supports SOPS and AWS SSM Parameter Store. Future versions may add support for other secret providers like HashiCorp Vault, AWS Secrets Manager, and more.

## Requirements

| Name | Version |

|------|---------|

|  [terraform](#requirement\_terraform) | >= 1.3 |

|  [aws](#requirement\_aws) | >= 4.0 |

|  [sops](#requirement\_sops) | >= 0.7 |

## Providers

| Name | Version |

|------|---------|

|  [aws](#provider\_aws) | >= 4.0 |

|  [sops](#provider\_sops) | >= 0.7 |

## Modules

No modules.

## Resources

| Name | Type |

|------|------|

| [aws_ssm_parameter.ssm_secrets](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/ssm_parameter) | data source |

| [sops_file.sops_secrets](https://registry.terraform.io/providers/carlpett/sops/latest/docs/data-sources/file) | data source |

## Inputs

| Name | Description | Type | Default | Required |

|------|-------------|------|---------|:--------:|

|  [secret\_mapping](#input\_secret\_mapping) | The list of secret mappings the application will need.
This creates secret values for the component to consume at `local.secrets[name]`.
For SOPS secrets: use type="sops" (default), file="path/to/sops/file.yaml", and name matching a key in the SOPS file.
For SSM secrets: use type="ssm" and path="/path/to/ssm/parameter". | 
list(object({
    name = string
    type = optional(string, "sops")
    path = optional(string, null)
    file = optional(string, null)
  }))
 | `[]` | no |

## Outputs

| Name | Description |

|------|-------------|

|  [all](#output\_all) | The final secrets pulled from various sources. |
