nconf-secrets

nconf-secrets is a storage extension that support loading docker swarm secrets.

How to use it

'use strict';

const nconf = require('nconf');

require('@vanderlaan/nconf-secrets');

nconf.argv()
  .env('__')
  .use('dockersecrets', { lowerCase: true, parseValues: true, separator: '__' });

console.log(nconf.get('http__shared_secret'));

Tell nconf-config where to find secrets

For example docker swarm will place secrets on the container at a given path. nconf-secrets will look at the default path used by docker swarm however if you configured your swarm to use a different path for secrets you can pass said path into nconf-secrets through the secretsDir option.

'use strict';

const nconf = require('nconf');

require('@vanderlaan/nconf-secrets');

nconf.argv()
  .env('__')
  .use('dockersecrets', {
    lowerCase: true,
    parseValues: true,
    separator: '__',
    secretsDir: '/my/secrets/path',
  });

console.log(nconf.get('http__shared_secret'));
