Why can't nginx or docker see the index.php file?

Question

PHP

I created my project folder in Ubuntu at: /home/NameUser/Projects/drupal9doc1
And put it there: Docker-based Drupal stack
I set up the files docker-compose.ymland .envthen wrote the command in the terminal: docker-compose up -d

And I have launched the necessary images for the local rise of the Drupal site

new_drupal9doc1_nginx
new_drupal9doc1_php
new_drupal9doc1_mariadb
new_drupal9doc1_pma
new_drupal9doc1_mailhog
new_drupal9doc1_crond
new_drupal9doc1_traefik

I created in the same index.php folder a file with a function phpinfo()to test how everything works.
And registered in the url http://drupal9doc1.localhost:8000
And I displayed on the page File not found instead of the php version.

Code part of docker-compose.yml file

php:
    image: wodby/drupal-php:$PHP_TAG
    container_name: "${PROJECT_NAME}_php"
    environment:

Answer 1

Solution: You need to DELETE the docker-compose-override.yml file from the project folder and everything will work.
