Deploy to Heroku

Deploying a Zetta server to Heroku

1. Click the Deploy to Heroku button on the bottom of the Zetta Cloud Starter GitHub repository.

2. Heroku will prompt you to setup a new Heroku account or log in with your existing account.

3. Pick an app name, like myherokuname-zetta.

You will now have a Zetta server instance running in the cloud.

Link Zetta servers together

Linking Zetta servers together requires one line of code.

1. In the server.js file that runs on your geo-distributed hub add the link() function to the zetta config:

   .link('http://myherokuname-zetta.herokuapp.com/')

2. Below is an example server.js file that inludes linking to a Zetta server running on Heroku.

   var zetta = require('zetta');
   var LED = require('zetta-led-mock-driver');
   var Photocell = require('zetta-photocell-mock-driver');
   
   var duskToDawnLight = require('./apps/dusk_to_dawn_light');
   
   zetta()
   .use(LED)
   .use(Photocell)
   .use(duskToDawnLight)
   .link('http://myherokuname-zetta.herokuapp.com/')
   .listen(1337, function(){
     console.log('Zetta is running at http://127.0.0.1:1337');
   });
