The information below was written in Oct 2017. In August 2019 AWS launched official support for multiple target groups per AWS ECS service. Please use that feature instead!

---

Unfortunately as of writing this (Oct 18, 2017) there is no built in integration for multiple target groups per AWS ECS service. Here are a few things you can try:

1. If your application just serves port 80 (HTTP) & port 443 (HTTPS) then you should consider using the application load balancer and terminating SSL at the load balancer. This will allow your application to function using just port 80.

#How to Construct Yourself UI in KeystoneJS

KeystoneJS provide Admin UI with one set of route controllers and view templates(list&item) for all of the models.But usually,you will need some custome views other than Admin UI to display models. Although the KeystoneJS documention don't tell us much about how to contruct custome view,we can learn this from the source code in skeleton project generated by yo keystone,or you can just check out the keystone demo project's source code.We will walk through the blog feature's implementation in this demo application to demonstrate how to construct custome UI in KeystoneJS application.

As KeystoneJS documention described in Routes & Views section,there is a routes/index.js file, where we bind application's URL patterns to the controllers that load and process data, and render the appropriate template.You can find following code in it:

app.get('/blog/:catego

var i = 0;

setInterval(function() {
  if (i++ % 2) {
    console.log('I\'m the child!');
  } else {
    console.error('I\'m the child!');
  }
}, 1500);
