sergioaugrod/vaultex

HashiCorp Vault client for Elixir.

🔒 Vaultex

A very simple elixir client that authenticates, reads and writes secrets from HashiCorp's Vault. As listed on Vault Libraries.

Installation

The package can be installed as:

1. Add vaultex to your list of dependencies in mix.exs:

def deps do
  [{:vaultex, "~> 0.5"}]
end

2. Ensure vaultex is started before your application:

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.

You can skip SSL certificate verification with :vaultex, vault_ssl_verify: true option or VAULT_SSL_VERIFY=true environment variable.

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 docs for supported auth backends.

...
iex> Vaultex.Client.auth(:app_id, {app_id, user_id})

iex> Vaultex.Client.auth(:userpass, {username, password})

iex> Vaultex.Client.auth(:ldap, {username, password})

iex> Vaultex.Client.auth(:github, {github_token})

iex> Vaultex.Client.auth(:approle, {role_id, secret_id})

iex> Vaultex.Client.auth(:token, {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}
