Terraform provider to automate the creation of BLESS deployments

---

This is a fork of chanzuckerberg/bless, updated to provide a darwin/arm64 binary, and updates to the BLESS lambda to provide support for ED25519 CA private keys.

Terraform provider to automate the creation of BLESS deployments.

bless_ca

This provider generates a BLESS CA without leaking any sensitive material to the terraform state store. The private part of the key is encrypted with a password. This password is then encrypted through KMS so that it is compatible with BLESS.

Example usage

provider "bless" {
  region  = "us-east-1"
  profile = "<aws_profile>"
}

resource "bless_ca" "example" {
  kms_key_id = "<kms_key_id>"
}

# The encrypted CA private key
output "encrypted_ca" {
  value = "${bless_ca.example.encrypted_ca}"
}

# The CA public key
output "ca" {
  value = "${bless_ca.example.public_key}"
}

# The KMS encrypted CA password
output "password" {
  value = "${bless_ca.example.encrypted_password}"
}

This module only creates logical resources and therefore only contributes to terraform state. Does not create externally managed resources. In order to generate a new key then, you must taint the resource. Terraform will then generate a new key on the next run.

terraform taint bless.example

bless_lambda

This data source creates a zip with the lambda code. Generally used with a lambda resource

Example usage

provider "bless" {
  region  = "us-east-1"
  profile = "<aws_profile>"
}

resource "bless_ca" "example" {
  kms_key_id = "<kms_key_id>"
}

data "bless_lambda" "code" {
  encrypted_password = "${bless_ca.example.encrypted_password}"
  encrypted_ca = "${bless_ca.example}"
  service_name = "my-bless-example" # give this CA a name
  kmsauth_key_id = "<kmsauth_key_id>"
  output_path = "${path.module}/bless.zip"
}

resource "aws_lambda_function" "bless" {
  filename = "${path.module}/bless.zip"
  source_code_hash = "${data.bless_lambda.code.output_base64sha256}"
  ...
}
