PHP-FPM based containers, adding PHP extensions that we often use:

Support for locales:

• en_GB.UTF-8
• en_US.UTF-8
• nl_NL.UTF-8
• de_DE.UTF-8
• fr_FR.UTF-8
• es_ES.UTF-8

Enabled default PHP extensions:

• gd
• exif
• mcrypt
• zip
• mbstring
• intl
• bcmath
• curl
• pdo_mysql
• xsl
• soap
• mysqli
• simplexml
• sockets
• xmlrpc
• opcache
• mysql
• ldap
• memcache
• memcached
• redis
• imagick

Extra software

Used for apps that have no separated front-end (like react), we have added nodejs so these can also be build inside the same container:

• nodejs
• npm
• yarn
• bower
• gulp
• pm2

EXAMPLE docker-compose.yml, using the VIRTUAL_HOST tag and the jwilder-proxy:

version: '3'
services:
    web:
        image: oberonamsterdam/apache24-fpm
        restart: always
        network_mode: "bridge"
        environment:
            - "VIRTUAL_HOST=${DOCKER_VHOST}"
        links:
            - php
        depends_on:
            - php
        volumes:
            - .:/app/:cached

    php:
        image: oberonamsterdam/php:7.4-fpm
        restart: always
        network_mode: "bridge"
        volumes:
            - .:/app/:cached
        environment:
            - "PHP_SESSION_SAVE_HANDLER=redis"
            - "PHP_SESSION_SAVE_PATH=tcp://redis:6379"
        links:
            - redis
        depends_on:
            - redis

    redis:
        image: redis:alpine
        restart: always
        network_mode: "bridge"

DEFAULT VALUES:

These values can be overwritten in your .env or "environment"-tag in your docker-compose.yml:

PHP_MAX_EXECUTION_TIME=120
PHP_MEMORY_LIMIT=256M
PHP_UPLOAD_LIMIT=8M
PHP_OPCACHE_LIMIT=64M
PHP_OPCACHE_REVALIDATE=2
PHP_SESSION_SAVE_HANDLER=files
PHP_SESSION_SAVE_PATH=""
PHP_SMTP_HOST=localhost
PHP_MAX_INPUT_VARS=1000

For example, you can add a redis container and change the redis-settings in your PHP-container:

version: '3'
services:
    php:
        image: oberonamsterdam/php:7.4-fpm
        network_mode: "bridge"
        environment:
            - "PHP_SESSION_SAVE_HANDLER=redis"
            - "PHP_SESSION_SAVE_PATH=tcp://redis:6379"
        links:
            - redis
        depends_on:
            - redis

    redis:
        image: redis:alpine
        network_mode: "bridge"

For development, set PHP_OPCACHE_REVALIDATE to "0", the default value "2" is somewhat of a tradeoff.
