# The example below uses the PHP Apache image as the foundation for running the app.
# By specifying the "7.4.28-apache" tag, it will also use whatever happens to be the
# most recent version of that tag when you build your Dockerfile.
# If reproducability is important, consider using a specific digest SHA, like
# php@sha256:99cede493dfd88720b610eb8077c8688d3cca50003d76d1d539b0efc8cca72b4.
FROM php:7.4.28-apache

# Copy app files from the app directory.
COPY . /var/www/html

# Your PHP application may require additional PHP extensions to be installed
# manually. For detailed instructions for installing extensions can be found, see
# https://github.com/docker-library/docs/tree/master/php#how-to-install-more-php-extensions
# The following code blocks provide examples that you can edit and use.
#
# Add core PHP extensions, see
# https://github.com/docker-library/docs/tree/master/php#php-core-extensions
# This example adds the apt packages for the 'gd' extension's dependencies and then
# installs the 'gd' extension. For additional tips on running apt-get:
# https://docs.docker.com/go/dockerfile-aptget-best-practices/
# RUN apt-get update && apt-get install -y \
#     libfreetype-dev \
#     libjpeg62-turbo-dev \
#     libpng-dev \
# && rm -rf /var/lib/apt/lists/* \
#     && docker-php-ext-configure gd --with-freetype --with-jpeg \
#     && docker-php-ext-install -j$(nproc) gd
#
# Add PECL extensions, see
# https://github.com/docker-library/docs/tree/master/php#pecl-extensions
# This example adds the 'redis' and 'xdebug' extensions.
# RUN pecl install redis-5.3.7 \
#    && pecl install xdebug-3.2.1 \
#    && docker-php-ext-enable redis xdebug

# Use the default production configuration for PHP runtime arguments, see
# https://github.com/docker-library/docs/tree/master/php#configuration
RUN mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"

# Switch to a non-privileged user (defined in the base image) that the app will run under.
# See https://docs.docker.com/go/dockerfile-user-best-practices/
USER www-data

# Here the instructions define your application as a service called "server".
# This service is built from the Dockerfile in the current directory.
# You can add other services your application may depend on here, such as a
# database or a cache. For examples, see the Awesome Compose repository:
# https://github.com/docker/awesome-compose
services:
  server:
    build:
      context: .
    ports:
      - 9009:80

# The commented out section below is an example of how to define a PostgreSQL
# database that your application can use. `depends_on` tells Docker Compose to
# start the database before your application. The `db-data` volume persists the
# database data between container restarts. The `db-password` secret is used
# to set the database password. You must create `db/password.txt` and add
# a password of your choosing to it before running `docker-compose up`.
#     depends_on:
#       db:
#         condition: service_healthy
#   db:
#     image: postgres
#     restart: always
#     user: postgres
#     secrets:
#       - db-password
#     volumes:
#       - db-data:/var/lib/postgresql/data
#     environment:
#       - POSTGRES_DB=example
#       - POSTGRES_PASSWORD_FILE=/run/secrets/db-password
#     expose:
#       - 5432
#     healthcheck:
#       test: [ "CMD", "pg_isready" ]
#       interval: 10s
#       timeout: 5s
#       retries: 5
# volumes:
#   db-data:
# secrets:
#   db-password:
#     file: db/password.txt
