How to publish services with ssl using docker-compose?

Question

I have a service using finatra server running on docker container. Currently I am using letsencrypt , and I created my .pfx file etc. But I don't know how to use it with docker-compose. I have a keystore folder inside my project which has my ssl files. Here is my docker-compose.yml

version: '2'
services:
    test:
        build: target/docker/stage
        ports:
            - "9999:9999"
            - "9990:9990"
        links:
            - mongo:mongo
        depends_on:
            - mongo

    mongo:
        image: mongo
        ports:
            - "27017:27017"
        volumes:
            - ./mydb:/data/db

I recommend using nginx and its SSL Termination capability: https://docs.nginx.com/nginx/admin-guide/security-controls/terminating-ssl-http/

The nginx service should be the entry point to your application, where you terminate SSL using your provided cert/key then pass unencrypted traffic between your container apps over the overlay network.

It's a best practice to terminate SSL like this, and if you do want to encrypt network traffic within your cluster, then do so with separate certs from your ingress controller.
