Question

Docker

The project was successfully built in docker. Created php and ngnix containers. DB is not required yet.
docker-compose.yml

version: "3.7"
services: 
    nginx:
        image: nginx:latest
        ports:
            - "80:80"
            - "443:443"
        volumes:
            - ./configs/nginx/:/etc/nginx/conf.d:cached
            - ./www/:/var/www:cached
            - ./logs:/var/log/nginx:cached
        links: 
            - php
    php:
        build: ./images/php
        #links:
            #- percona
            #- redis

        volumes:
            - ./www:/var/www:cached

    #redis:
        #image: redis:latest
        #ports:
           # - "6379:6379"
        #links:
            #- percona

    #percona:
        #image: percona:8.0.20-11
        #ports:
            #- "3306:3306"

localhost in browser: blank page with File not found message.
localhost/web/index and other url combinations tried, same message.

The feeling that the url just does not lead there. The web has a file index.
