How to use SSL/TLS on ECS Fargate

I am trying to use SSL/TLS for Python Flask/Waitress server running the ECS Fargate. I haven't found a solution for our use case.

Here are the designs for the ECS Fargate:

• Container will only interacts with backend AWS Lambda
• Public IP disabled, only private ip is enabled.
• No use of load balancer. The Python server is stateful and spinning a new container when requested is more cost effective.

How should I make a HTTPS request from Lambda to the ECS Fargate?

Solved the issue:

• Create a self-signed cert using OpenSSL in Flask server
• Trust self-signed certs in Lambda
