add this to an already existing container

[arcanisgk]

I'm using docker and I don't see the correct way to merge two images... so I wouldn't want to have to add a separate container because I don't know how to connect it to the other container where I already have something running before...

Any way to add this to an already existing container with the following previous configuration:

docker-compose.yml:

version: "3.9"

services:

  reverse-proxy:
    env_file:
      - .env
    container_name: Proxy-Server
    image: nginxproxy/nginx-proxy
    restart: always
    depends_on:
      - webserver
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - ./config/ssl:/etc/nginx/certs
    extra_hosts:
      - "lh-stack.dock:127.0.0.1"
      - "pma.lh-stack.dock:127.0.0.1"
    ports:
      - 80:80
      - 443:443
    networks:
      - lamp-network
    environment:
      - TRUST_DOWNSTREAM_PROXY=true
      - ENABLE_WEBSOCKETS=true
    privileged: true
    tty: true

  webserver:
    env_file:
      - .env
    container_name: LH-STACK-Web-Server
    build:
      context: ./bin/php81
      dockerfile: Dockerfile.secure
      args:
        VIRTUAL_HOST: lh-stack.dock
    restart: always
    expose:
      - 80
    networks:
      - lamp-network
    volumes:
      - ./../project:/var/www/html:rw
      - ./../project/public:/var/www/html/public:rw
      - ./config/vhost:/etc/apache2/sites-enabled
      - ./config/php/php.ini:/usr/local/etc/php/php.ini
      - ./config/cron:/etc/cron-task
      - ./log/apache2:/var/log/apache2
      - ./log/cron:/var/log/cron
    environment:
      VIRTUAL_HOST: lh-stack.dock
      LH_WEB_MASTER: icarosnet@gmail.com
      LH_APACHE_DOCUMENT_ROOT: /var/www/html
      LH_DOCUMENT_ROOT: /public
    extra_hosts:
      - "host.docker.internal:host-gateway"
    labels:
      - "lh2.setup.description=Web Server"
      - "lh2.setup.role=webserver"
    privileged: true
    tty: true

Dockerfile:
