Create a simple Docker Compose project

Go to Project 4 from the git repository root:

cd projects/p04

Project structure:

.
├── Dockerfile
├── docker-compose.yml
└── www
    └── index.php

The content of index.php

<?php

file_put_contents(__DIR__ . '/access.txt', date('Y.m.d. H:i:s') . "\n", FILE_APPEND);

echo 'P04<br/>';
echo nl2br(file_get_contents(__DIR__ . '/access.txt'));

the compose file

volumes:
  php_www:

services:
  php:
    image: localhost/p04_php
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - php_www:/var/www
    ports:
      - "8080:80"

and the Dockerfile

FROM php:7.4-alpine

LABEL hu.itsziget.ld.project=p04

COPY www /var/www

CMD ["php", "-S", "0.0.0.0:80", "-t", "/var/www"]

Build an image and start the container using Docker Compose:

docker compose up -d

Check the container:

docker compose ps
# The name of the container: p04_php_1

Check the networks:

docker network ls
# New bridge network: p04_default

Delete the container, and networks with Docker Compose:

docker compose down

Or delete the volumes too.

docker compose down --volumes
