How to use this image

With Command Line

For PHP projects run through the command line interface (CLI), you can do the following.

Create a Dockerfile in your PHP project

FROM jtreminio/php:8.1
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
CMD [ "php", "./your-script.php" ]

Then, run the commands to build and run the Docker image:

docker build -t my-php-app .
docker run -it --rm --name my-running-app my-php-app

Run a single PHP script

For many simple, single file projects, you may find it inconvenient to write a complete Dockerfile. In such cases, you can run a PHP script by using the PHP Docker image directly:

docker run -it --rm \
    --name my-running-script \
    -v "$PWD":/usr/src/myapp \
    -w /usr/src/myapp \
    jtreminio/php:8.1 php your-script.php

Note that all variants of the PHP image contain the PHP CLI.

Without PHP-FPM

I have created images without PHP-FPM (CLI only).

Click here for jtreminio/php-cli.

With Nginx or Apache

I have created full-featured Nginx/Apache versions of these images.

Click here for jtreminio/php-nginx.

About these images

These images are built from Ondřej Surý's PPA

They come with the most common PHP modules baked in. For a full list please see below.

Composer is installed at /usr/local/bin/composer

PHP-CLI INI and PHP-FPM conf files are saved to standard location across all versions to make managing them simpler.

• PHP INI used by PHP-FPM is at /etc/php/fpm.ini
• PHP INI use by CLI is at /etc/php/cli.ini
• PHP-FPM main conf is at /etc/php/fpm.conf

Two blank INI files have been provided for you to write your custom INI settings.

• /etc/php/cli-custom.ini
• /etc/php/php-custom.ini

Use -v your-file.ini:/etc/php/cli-custom.ini to add your settings. These two files are loaded last so its contents will take precedence over everything else.

PHP-FPM includes fix for logging to stdout and stderr created by https://github.com/phpdocker-io/base-images

PHP-FPM listens on port 9000 and is run automatically by runit:

docker container run -it --rm \
    jtreminio/php:8.1

INI Through Environment Variables

You can set a large number of PHP INI settings using environment variables.

A full list of supported directives can be found here.

You can read about this in more detail here.

docker container run -it --rm \
    jtreminio/php:8.1 php -i | grep display_errors

100:display_errors => Off => Off

vs

docker container run -it --rm \
    -e PHP.display_errors=1 \
    jtreminio/php:8.1 php -i | grep display_errors

100:display_errors => STDOUT => STDOUT

Installed Modules

Many modules are installed and enabled by default:

• php-bcmath
• php-cli
• php-curl
• php-fpm
• php-intl
• php-json
• php-mbstring
• php-mysql
• php-opcache
• php-xml
• php-zip

More modules are installed but not enabled by default:

• php-amqp
• php-apcu
• php-gd
• php-igbinary

• stomp
• uploadprogress

You can enable these modules by using the PHP_INI_SCAN_DIR env var. A special shortcut has been created to more easily add modules:

docker container run -it --rm \
    -e PHP_INI_SCAN_DIR=:/p/amqp:/p/mailparse \
    jtreminio/php:8.1 php -v

The /p directory contains symlinks to other directories (if PHP version supports the module)

/p/amqp            -> /etc/php/extra-mods/amqp
/p/apcu            -> /etc/php/extra-mods/apcu
/p/geoip           -> /etc/php/extra-mods/geoip
/p/gnupg           -> /etc/php/extra-mods/gnupg
/p/imagick         -> /etc/php/extra-mods/imagick
/p/lua             -> /etc/php/extra-mods/lua
/p/mailparse       -> /etc/php/extra-mods/mailparse
/p/memcached       -> /etc/php/extra-mods/memcached
/p/mongodb         -> /etc/php/extra-mods/mongodb
/p/oauth           -> /etc/php/extra-mods/oauth
/p/pdo_sqlite      -> /etc/php/extra-mods/pdo_sqlite
/p/radius          -> /etc/php/extra-mods/radius
/p/raphf           -> /etc/php/extra-mods/raphf
/p/redis           -> /etc/php/extra-mods/redis
/p/solr            -> /etc/php/extra-mods/solr
/p/sqlite3         -> /etc/php/extra-mods/sqlite3
/p/ssh2            -> /etc/php/extra-mods/ssh2
/p/stomp           -> /etc/php/extra-mods/stomp
/p/uploadprogress  -> /etc/php/extra-mods/uploadprogress
/p/uuid            -> /etc/php/extra-mods/uuid
/p/xdebug          -> /etc/php/extra-mods/xdebug
/p/zmq             -> /etc/php/extra-mods/zmq

You can add as many of these as you want to PHP_INI_SCAN_DIR, make sure to prepend :.

You can read about this in greater detail by going to PHP Modules Toggled via Environment Variables.

Xdebug

Xdebug is installed but disabled by default:

docker container run -it --rm jtreminio/php:7.2 php -v

PHP 8.1.2 (cli) (built: Jan 24 2022 10:42:15) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
    with Zend OPcache v8.1.2, Copyright (c), by Zend Technologies

To enable Xdebug (ONLY on non-public servers!) you may use the PHP_INI_SCAN_DIR env var:

docker container run -it --rm \
    -e PHP_INI_SCAN_DIR=:/p/xdebug \
    jtreminio/php:8.1 php -v

PHP 8.1.2 (cli) (built: Jan 24 2022 10:42:15) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
    with Zend OPcache v8.1.2, Copyright (c), by Zend Technologies
    with Xdebug v3.1.2, Copyright (c) 2002-2021, by Derick Rethans

Note the prepended : in :/p/xdebug.

xdebug.remote_host is set to host.docker.internal by default. This will not work in Linux (yet). You must either pass your host IP directly, or use a gateway. I have found 172.17.0.1 to work in most cases:

docker container run -it --rm \
    -e PHP_INI_SCAN_DIR=:/p/xdebug \
    -e PHP.xdebug.client_host=172.17.0.1 \
    jtreminio/php:8.1 php -i | grep xdebug.client_host

639:xdebug.client_host => 172.17.0.1 => 172.17.0.1

A helper script has been created at /usr/bin/xdebug to help you debug CLI applications.

To use it, call it instead of php directly:

docker container run -it --rm \
    jtreminio/php:8.1 xdebug -v
