# AwsParameterStoreConfigProvider
[](https://hex.pm/packages/aws_parameter_store_config_provider)
AwsParameterStoreConfigProvider is an Elixir [release config provider](https://hexdocs.pm/elixir/Config.Provider.html) for loading secrets from [AWS Systems Manager Parameter Store](https://aws.amazon.com/systems-manager/features/#Parameter_Store) into app env at runtime.
Built with [ExAws.SSM](https://github.com/hellogustav/ex_aws_ssm)
## Installation
The package can be installed by adding `aws_parameter_store_config_provider` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:aws_parameter_store_config_provider, "~> 1.0.0"}
]
end
```
Configure [your release](https://hexdocs.pm/mix/Mix.Tasks.Release.html) and add AwsParameterStoreConfigProvider as a config provider
```
def project
[
releases: [
app: [
config_providers: [{AwsParameterStoreConfigProvider, nil}]
]
]
]
```
## Configuration
Read the [ExAws](https://github.com/ex-aws/ex_aws), and configure ex_aws with your credentials
## Usage
The provider will resolve secrets stored matching two patterns: strings or tuples. Tuples can contain a function to transform the secret
```elixir
config :my_app, MyApp.Endpoint,
secret_key_base: "secret:/my_app/secret_key_base",
config :my_app, MyApp.Repo,
hostname: "secret:/my_app/database/hostname",
username: "secret:/my_app/database/username",
password: "secret:/my_app/database/password",
database: "secret:/my_app/database/database",
port: {"secret:/my_app/database/port", fn port -> String.to_integer(port) end}
```
A string address is expected to include `secret:/path`
The transformation function is useful for changing a secret's datatype because everything comes out as a string
## Credits
This code was mostly copied straight from the [VaultConfigProvider](https://github.com/sevenmind/vault_config_provider) and made to support AWS Parameter Store
