ExVault

Elixir client library for HashiCorp Vault.

Documentation is published on HexDocs.

Installation

The package can be installed by adding exvault to your list of dependencies in mix.exs:

def deps do
  [
    {:exvault, "~> 0.1.0-beta.1"},
  ]
end

You can also install the latest code from GitHub:

def deps do
  [
    {:exvault, github: "praekeltfoundation/exvault", sparse: "apps/exvault"},
  ]
end

Basic Usage

Start by creating a client with an API URL and an authentication token:

client = ExVault.new(address: "https://127.0.0.1:8200", token: "abcd-1234")

This client can then be used to make various API calls. Assuming a v1 key-value secret backend is mounted at /secret_kv_v1:

{:ok, _} = ExVault.write(client, "secret_kv_v1/my_key", %{"hello" => "world"})

{:ok, resp} = ExVault.read(client, "secret_kv_v1/my_key")
%{"hello" => "world"} = resp.logical.data

{:ok, _} = ExVault.delete(client, "secret_kv_v1/my_key")

{:ok, resp} = ExVault.read(client, "secret_kv_v1/my_key")
%ExVault.Response.Error{status: 404} = resp.logical.data
