Guidance on running on AWS ECS

[code-bunny]

Running Thruster on HTTP is all grand and lovely, but when I went to set this up on HTTPS on ECS I had a few issues leading to it just not accepting any requests.

The setup I tried was an AWS ALB to a ip https target group which I then connected to my cluster with an ECS task. On the target group and ECS task I tried both http/2 and http/1 combinations and even tried public IP's. In all cases the Rails application and Thruster start up and then no traffic can get to the task, not even the health checks. I did check and even have work devops check the security groups. Best we can tell is that it can't open a connection.

Current theory is maybe it isn't compatible with a ALB.

Is there a recommended setup? Having HTTPS at the task level would be amazing.
