Xdebug: Windows + PhpStorm + Docker 桌面 + CodeIgniter

Question

I created a new CodeIgniter project and need to setup debugging with Xdebug against a container running in Docker Desktop. I'm not sure how to connect Xdebug to the container given my directory structure. I get an incoming connection dialog but not sure how to map it properly.

How do you map an incoming xdebug connection when your directory structure is split between a public folder which is the entry point for CodeIgniter and the rest of the CodeIgniter framework code in the server folder? It looks like this:

I was able to successfully create and run a docker deployment in PhpStorm:

Deploying 'Compose: docker'...
"C:\Program Files\Docker\Docker\resources\bin\docker-compose.exe" -f D:\Projects\my-project\devops\docker\docker-compose.yml up -d proxy database opp_web
opp_database is up-to-date
opp_proxy is up-to-date
opp_web is up-to-date
'Compose: docker' has been deployed successfully.

My docker-compose.yml file:

version: "3"

networks:
  opp-proxy:
    driver: bridge
  default:

services:
  proxy:
    image: "jwilder/nginx-proxy:latest"
    container_name: "opp_proxy"
    volumes:
      - "dhparam:/etc/nginx/dhparam"
      - "./files/certs/:/etc/nginx/certs"
      - "/var/run/docker.sock:/tmp/docker.sock:ro"
    restart: "always"
    networks:
      - "opp-proxy"
    ports:
      - "80:80"
      - "443:443"

  database:
    image: mysql:5.7
    container_name: "opp_database"
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_USER: dba
      MYSQL_PASSWORD: password
      MYSQL_DATABASE: opp
    volumes:
      - "db_data:/var/lib/mysql"
      - "./files/docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d"
    ports:
      - "23306:3306"

  opp_web:
    image: webdevops/php-apache-dev:7.4
    container_name: "opp_web"
    volumes:
      - "./files/entrypoint.d:/entrypoint.d"
      - "../../server:/app"
    environment:
      VIRTUAL_HOST: "opp.test"
      WEB_DOCUMENT_ROOT: "/app/public"
      PHP_DEBUGGER: xdebug
      XDEBUG_MODE: "develop,debug"
      XDEBUG_START_WITH_REQUEST: trigger
      XDEBUG_CLIENT_PORT: 9002
      XDEBUG_CLIENT_HOST: "host.docker.internal"
      XDEBUG_DISCOVER_CLIENT_HOST: 'false'
    depends_on:
      - database
    networks:
      - default
      - opp-proxy

volumes:
  db_data:
  dhparam:

When I try to map the incoming connection I would prefer to use Import mappings from deployment as it auto-detects the deployment but not sure what the deployment root should be set to:

I also tried all of these files as entry points when it auto-detects the paths:

Assuming I use Manually choose local file or project , I set a breakpoint in the server/app/Controllers/Home.php controller (default CodeIgniter index method that returns the welcome message), the breakpoint never gets hit. But if I set a breakpoint in the server/public/index.php I can step through successfully with the debugger. So there is some issue when the CodeIgniter framework gets run and doesn't debug into the app/Controllers/Home.php file even though the page loads successfully. How can I debug into the app folder?

Thanks to the comments from @LazyOne, I just needed to add a path for the server to be /app/ :
