This package provides a [Hush](https://github.com/gordalina/hush) Provider to resolve Amazon Web Services's [Secrets Manager](https://aws.amazon.com/secrets-manager/) secrets.

Documentation can be found at [https://hexdocs.pm/hush_aws_secrets_manager](https://hexdocs.pm/hush_aws_secrets_manager).

## Installation

The package can be installed by adding `hush_aws_secrets_manager` to your list

of dependencies in `mix.exs`:

```elixir

def deps do

  [

    {:hush, "~> 1.0"},

    {:hush_aws_secrets_manager, "~> 1.0.0"}

  ]

end

```

This module relies on `ex_aws` to talk to the AWS API. As such you need to configure it, below is an example, but you can read alternative ways of configuring it in [their documentation](https://github.com/ex-aws/ex_aws).

As the provider needs to start `ex_aws` application, it needs to registered as a provider in `hush`, so that it gets loaded during startup.

```elixir

# config/config.exs

alias Hush.Provider.AwsSecretsManager

config :ex_aws,

  access_key_id: [{:system, "AWS_ACCESS_KEY_ID"}],

  secret_access_key: [{:system, "AWS_SECRET_ACCESS_KEY"}]

# ensure hush loads AwsSecretsManager during startup

config :hush,

  providers: [AwsSecretsManager]

```

### AWS Authorization

In order to retrieve secrets from AWS, ensure the service account you use has a similar policy as:

```json

{

  "Version": "2012-10-17",

  "Statement": [

    {

      "Effect": "Allow",

      "Action": "secretsmanager:GetSecretValue",

      "Resource": [

        "arn:aws:secretsmanager:::secret:",

        "arn:aws:secretsmanager:us-east-1:000000000000:secret:config/password-MzBAO2"

      ]

    }

  ]

}

```

## Usage

The following example reads the password and the pool size for CloudSQL from secret manager into the ecto repo configuration.

```elixir

# config/prod.exs

alias Hush.Provider.AwsSecretsManager

config :app, App.Repo,

  password: {:hush, AwsSecretsManager, "CLOUDSQL_PASSWORD"},

  pool_size: {:hush, AwsSecretsManager, "ECTO_POOL_SIZE", cast: :integer, default: 10}

```
