var server = { host: process.env.ES_HOST || 'localhost'
             , port: process.env.ES_PORT || 9200
             , secure: false
             , auth: { username: process.env.ES_USERNAME
                     , password: process.env.ES_PASSWORD
                     }
             }

var serverOptions = {
  host:   process.env.ES_HOST,
  port:   process.env.ES_PORT,
  secure: false,
  auth:   { username: process.env.ES_USERNAME,
