node-vault

A client for the HTTP API of HashiCorp's [Vault] written for Node.js.

install

make sure to use node.js version >= 6

npm install node-vault

test

Run tests inside docker to do also nice integration testing:

docker-compose up --force-recreate test

This will create containers for vault, postgres and running the tests inside docker.

usage

init and unseal

var options = {
  apiVersion: 'v1', // default
  endpoint: 'http://127.0.0.1:8200', // default
  token: '1234' // optional client token; can be fetched after valid initialization of the server
};

// get new instance of the client
var vault = require("node-vault")(options);

// init vault server
vault.init({ secret_shares: 1, secret_threshold: 1 })
.then( (result) => {
  var keys = result.keys;
  // set token for all following requests
  vault.token = result.root_token;
  // unseal vault server
  return vault.unseal({ secret_shares: 1, key: keys[0] })
})
.catch(console.error);

write, read and delete secrets

vault.write('secret/hello', { value: 'world', lease: '1s' })
.then( () => vault.read('secret/hello'))
.then( () => vault.delete('secret/hello'))
.catch(console.error);

docs

Just generate [docco] docs via npm run docs.

examples

Please have a look at the [examples] and the generated [feature list] to see what is already implemented.

Instead of installing all the dependencies like vault itself, postgres and other stuff you can use [docker] and [docker-compose] to link and run multiple docker containers with all of its dependencies.

git clone [e-mail]:kr1sp1n/node-vault.git
cd node-vault
docker-compose up vault

Now you can run the examples from another terminal window.

First of all you should initialize and unseal the vault:

node example/init.js

You should see root_token: followed by a long key in the response. Please copy that long key and export it as environment variable:

export VAULT_TOKEN=<insert long key here>

Now you are able to run all of the other [examples]:

node example/policies.js

##Connecting to vault through a bastion host To connect to a vault server in a private network with a bastion host, you'll need to first open a connection:

ssh -D <socks4Port> bastion.example.com

const SocksProxyAgent = require('socks-proxy-agent');
const agent = new SocksProxyAgent(`socks://127.0.0.1:${socks4Port}`, true);
const options = {
  apiVersion: 'v1',
  rpOptions: {
    agent,
  },
};

const vault = require('node-vault')(options);
