Keycloak on remote server

Configuring the server
1

I have key cloak running well in a local container
when I try to push it up to the cloud using a docker container it says I am not using a secure connection.
I am using a Postgres dump to restore my realm, create users blah blah
I have obtained 2 files tls. cert and tls. key and am working towards putting them in a /etc/x509/https folder on the server in the cloud. then I am to add them as volumes? in my docker-compose file. not sure how to do this.
docker-compose file follows ( I know the admin user and password are not being used due to restoring the postgres dump, I just haven’t gotten around to deleting them

    image: jboss/keycloak
    build:
      context: ./keycloak
    environment:
      DB_VENDOR: POSTGRES
      DB_ADDR: postgres
      DB_DATABASE: keycloak
      DB_USER: keycloak
      DB_SCHEMA: public
      DB_PASSWORD: password
      KEYCLOAK_USER: admin
      KEYCLOAK_PASSWORD: Pa55w0rd
    ports:
      - 8080:8080
      - 8443:8443
    volumes:
      - certs:/etc/x509/https # map certificates to container

    depends_on:
      - postgres
volumes:
  postgres_data:
    driver: local
  certs:/etc/x509/https
    driver: local

any help appreciated
