🔒 Vaultex

A very simple read-only elixir client that authenticates and reads secrets from HashiCorp's Vault.

Installation

The package can be installed as:

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

def deps do
  [{:vaultex, "~> 0.2.1"}]
end

1. 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.

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.
