# :lock: Vaultex
[]()
[]()
A very simple elixir client that authenticates and reads secrets from HashiCorp's Vault. As listed on [Vault Libraries](https://www.vaultproject.io/docs/http/libraries.html#elixir).
## Installation
The package can be installed as:
1. Add vaultex to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:vaultex, "~> 0.3"}]
end
```
2. Ensure vaultex is started before your application:
```elixir
def application do
[applications: [:vaultex]]
end
```
## Configuration
You can configure your vault endpoint with a single environment variable:
* `VAULT_ADDR`
Or a single application variable:
* `:vaultex, :vault_addr`
An example value for `VAULT_ADDR` is `http://127.0.0.1:8200`.
Alternatively the vault endpoint can be specified with environment variables:
* `VAULT_HOST`
* `VAULT_PORT`
* `VAULT_SCHEME`
Or application variables:
* `:vaultex, :host`
* `:vaultex, :port`
* `:vaultex, :scheme`
These default to `localhost`, `8200`, `http` respectively.
## Usage
To read a secret you must provide the path to the secret and the authentication backend and credentials you will use to login. See the [Vaultex.Client.auth/2](https://hexdocs.pm/vaultex/Vaultex.Client.html#auth/2) docs for supported auth backends.
```elixir
...
iex> Vaultex.Client.auth(:app_id, {app_id, user_id})
iex> Vaultex.Client.auth(:userpass, {username, password})
iex> Vaultex.Client.auth(:github, {github_token})
...
iex> Vaultex.Client.read "secret/bar", :github, {github_token} #returns {:ok, %{"value" => bar"}}
...
iex> Vaultex.Client.write "secret/foo", %{"value" => "bar"}, :app_id, {app_id, user_id}
```
