I have a written a web app which i want to deploy, it should be accessible using HTTPS. Web app is dockerized into 4 containers : backend , frontend , postgres and redis container.

Site is accessible using http when i tried deploying using aws ec2 . But becuause backend only accept only https connection frontend can not talk to backend. As https is currently not supported.

I dont want to purchase a domain . i want to test it over https and check if my implementation work correclty on https and also be able to show case my project as a live demo.( i have tested everything locally it works as expected)

how can i get my web app working utilizing https using ec2 ?
