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:
- 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.
