PHP Docker Images

📦 Simplified PHP Docker images for effortless customization and extension setup.

Our Docker images cover PHP versions from 5.6 to 8.4, available in CLI, ZTS, FPM, FPM/Apache2, FPM/Nginx, RoadRunner, FrankenPHP, and Nginx Unit variants. The Docker images are available for both Debian and Alpine versions.

Docker Hub: https://hub.docker.com/r/shinsenter/php
GitHub Packages: https://code.shin.company/php/pkgs/container/php

Introduction

Our PHP Docker images are based on the official PHP Docker images. These images facilitate the easy adjustment of PHP and PHP-FPM settings using environment variables, eliminating the need to rebuild images when making configuration changes.

These images also come with the latest version of Composer and popular web servers like Apache2, Nginx, RoadRunner, FrankenPHP or Nginx Unit. This setup allows for faster project initiation without additional installations.

🪶 Info: While built on the official PHP images and including more useful extensions, we have significantly reduced the image sizes compared to the base images. This optimization improves download times and resource usage without sacrificing functionality, thanks to the docker-squash project.

Docker Image Variants

Our image tags cover PHP versions from 5.6 to 8.4^(*), available in cli, zts, fpm, fpm-nginx, fpm-apache, roadrunner⁽¹⁾, frankenphp⁽²⁾, and unit-php⁽³⁾ variants. The Docker images are available for both Debian and Alpine versions.

ℹ️ Note: We no longer maintain the -tidy tag names. If you are using Docker images with this tag, please replace them with the -alpine variant.

Examples:

shinsenter/php:7.2-cli
shinsenter/php:7.3-zts
shinsenter/php:7.4-fpm
shinsenter/php:8.0-fpm-apache
shinsenter/php:8.1-fpm-nginx
shinsenter/php:8.2-roadrunner ⁽¹⁾
shinsenter/php:8.3-frankenphp ⁽²⁾
shinsenter/php:8.4-unit-php ⁽³⁾

^(*): The latest stable version is 8.3.
⁽¹⁾: PHP with RoadRunner server. The roadrunner variant supports PHP >= 8.0.
⁽²⁾: FrankenPHP is still in BETA. The frankenphp variant supports PHP >= 8.2.
⁽³⁾: PHP with Nginx Unit server. The unit-php variant supports PHP >= 7.4.

Explore all available tags on our Docker Hub.

For stable versions suitable for production, we also offer version tags on another repository.

Examples

You can easily run a container by copying and pasting one of these docker run commands:

CLI

# non-interactive
docker run --rm shinsenter/php:8.4-cli php -m

# interactive
docker run -it -v ./myproject:/var/www/html shinsenter/php:8.4-cli

PHP-FPM

docker run -v ./myproject:/var/www/html -p 9000:9000 shinsenter/php:8.4-fpm

PHP-FPM + Nginx (or Apache, RoadRunner, FrankenPHP, Nginx Unit)

# with Nginx
docker run -v ./myproject:/var/www/html -p 80:80 -p 443:443 shinsenter/php:8.4-fpm-nginx

# with Apache
docker run -v ./myproject:/var/www/html -p 80:80 -p 443:443 shinsenter/php:8.4-fpm-apache

# with RoadRunner
docker run -v ./myproject:/var/www/html -p 80:80 -p 443:443 shinsenter/php:8.3-roadrunner

# with FrankenPHP
docker run -v ./myproject:/var/www/html -p 80:80 -p 443:443 shinsenter/php:8.3-frankenphp

# with Nginx Unit
docker run -v ./myproject:/var/www/html -p 80:80 -p 443:443 shinsenter/php:8.3-unit-php

Customizing Settings via Environment Variables

These images allow customizing PHP and PHP-FPM settings through environment variables instead of rebuilding images.

The environment variable names follow these conventions:

Variables are prefixed with PHP_ to avoid conflicts with other application variables.
The rest of the variable name matches the configuration directive name from php.ini or php-fpm.conf:
- PHP ini directives: https://www.php.net/manual/en/ini.list.php
- PHP-FPM directives: https://www.php.net/manual/en/install.fpm.configuration.php
Directive names are converted to CONSTANT_CASE - uppercase with underscores instead of dots or dashes.

This naming convention helps you easily identify which environment variable applies to which PHP/PHP-FPM configuration directive.

👉🏻 Info: By default, the $PHP_* environment variables only take effect when set before starting the container. To dynamically change PHP configurations using $PHP_* environment variables while running commands within the container, you need to start your container with the ALLOW_RUNTIME_PHP_ENVVARS=1 environment variable.

💡 Hint: Run php-envvars in the container to get a full list of default $PHP_* environment variables.

Examples

Command Line

docker run \
    -v ./myproject:/var/www/html \
    -e PHP_DISPLAY_ERRORS='1' \
    -e PHP_POST_MAX_SIZE='100M' \
    -e PHP_UPLOAD_MAX_FILESIZE='100M' \
    -e PHP_SESSION_COOKIE_HTTPONLY='1' \
    shinsenter/php:8.4 php -i

With docker-compose.yml

services:
  web:
    image: shinsenter/php:8.4-fpm-nginx
    environment:
      PHP_DISPLAY_ERRORS: "1"
      PHP_POST_MAX_SIZE: "100M"
      PHP_UPLOAD_MAX_FILESIZE: "100M"
      PHP_SESSION_COOKIE_HTTPONLY: "1"

Explanation

Environment Variable	Explanation	Equivalent Configuration
PHP_DISPLAY_ERRORS=1	Enables displaying errors during development.	`display_errors 1`
PHP_POST_MAX_SIZE=100M	Increases the maximum post size from the default 8MB.	`post_max_size 100M`
PHP_UPLOAD_MAX_FILESIZE=100M	Increases the maximum upload file size from the default 2MB.	`upload_max_filesize 100M`
PHP_SESSION_COOKIE_HTTPONLY=1	Enables the HttpOnly flag for session cookie security.	`session.cookie_httponly 1`

💡 Hint: Run php-envvars in the container to get a full list of default $PHP_* environment variables.

Pre-installed PHP Extensions

Popular PHP extensions are pre-installed by default, allowing projects to get started faster without additional installation.

apcu
bcmath
calendar
exif
gd
gettext
igbinary
intl
msgpack
mysqli
opcache
pcntl
pdo_mysql
pdo_pgsql
redis
sodium
uuid
yaml
zip

👉🏻 Info: The pre-installed PHP extensions from the official Docker images are excluded from this list.

💡 Hint: Run docker run --rm shinsenter/php:8.4-cli php -m in the container to get a list of extensions (you can replace 8.4 with a specific PHP version).

Adding PHP Extensions

These images use a simple command called phpaddmod to install PHP extensions.

You don't need to run the more complex docker-php-ext-install command or manually edit the php.ini file; phpaddmod handles the installation and configuration for you.

For example, in your Dockerfile:

FROM shinsenter/php:8.4-fpm-nginx

# Install imagick, swoole and xdebug
RUN phpaddmod imagick swoole xdebug

# Add your instructions here
# For example:
# ADD --chown=$APP_USER:$APP_GROUP ./myproject/ /var/www/html/

👉🏻 Info: The phpaddmod command is a wrapper around the mlocati/docker-php-extension-installer utility, which takes care of all required steps to compile and activate the extensions.

💡 Hint: If you're having trouble figuring out which extensions can be installed, have a look at their documentation.

Application Directory

The default application directory is /var/www/html and can be customized via the $APP_PATH environment variable:

docker run -p 80:80 -p 443:443 -p 443:443/udp \
    -v "$PWD":/app \
    -e APP_PATH=/app \
    shinsenter/php:8.4-fpm-nginx

This changes the web application directory to /app.

Moreover, the default document root (a relative path inside the application directory that contains your index.php file) can be customized by setting the $DOCUMENT_ROOT environment variable:

docker run -p 80:80 -p 443:443 -p 443:443/udp \
    -v "$PWD":/app \
    -e APP_PATH=/app \
    -e DOCUMENT_ROOT=/public \
    shinsenter/php:8.4-fpm-nginx

This would change the document root path to /app/public.

Customizing Container User and Group in Docker

Override the default user and group settings by setting environment variables when running the container.

Available variables:

Environment Variable	Description	Default
`APP_USER`	Username inside the container	`www-data`
`APP_GROUP`	Group name inside the container	`www-data`
`APP_UID`	Numeric UID of the user	UID in container
`APP_GID`	Numeric GID of the group	GID in container

For example, to run a container as user myapp with UID 5000:

docker run -p 80:80 -p 443:443 -p 443:443/udp \
    -e APP_USER=myapp \
    -e APP_UID=5000 \
    shinsenter/php:8.4-fpm-nginx

Or in a docker-compose.yml:

services:
  web:
    image: shinsenter/php:8.4-fpm-nginx
    environment:
      APP_USER: "myapp"
      APP_UID: "5000"

Autorun Scripts

Shell scripts placed in the /startup/ directory will automatically run when the container starts, in alphabetical order by filename. This feature can initialize projects before the main program runs, saving time by executing initialization scripts automatically.

Usage Example

Copy a script called 00-migration into /startup/ via a Dockerfile:

Note: Ensure the script has executable permissions.

FROM shinsenter/php:8.4-cli

ADD ./autorun/00-migration /startup/00-migration
RUN chmod +x /startup/00-migration

# Add your instructions here
# For example:
# ADD --chown=$APP_USER:$APP_GROUP ./myproject/ /var/www/html/

👉🏻 Info: The startup directory already includes a script called 99-greeting that prints a welcome message when the container starts.

Disable Autorun Scripts

To disable autorun scripts, set DISABLE_AUTORUN_SCRIPTS=1 as an environment variable.

For example, with docker run:

docker run -e DISABLE_AUTORUN_SCRIPTS=1 shinsenter/ubuntu-s6:latest bash

Or in docker-compose.yml:

services:
  web:
    image: shinsenter/ubuntu-s6:latest
    environment:
      DISABLE_AUTORUN_SCRIPTS: "1"

Using Cron Jobs

To enable cron jobs in containers, you can start the container with ENABLE_CRONTAB=1. This setting activates the Crontab service, which loads settings from the directory specified by $CRONTAB_DIR (default is /etc/crontab.d).

The cron jobs will run as the user defined by $APP_USER:$APP_GROUP, which by default is www-data:www-data, and with the home directory set by $CRONTAB_HOME (default is /var/www/html).

Here is an example Dockerfile to add a crontab:

FROM shinsenter/php:latest

ENV ENABLE_CRONTAB=1

# create crontab entry via RUN instruction
RUN echo '* * * * * echo "echo This line will run every minute!" | tee /tmp/cron-every-minute.txt' >> /etc/crontab.d/sample1;

# or copy crontab entries via ADD instruction
ADD ./sample2 /etc/crontab.d/

The format of a crontab entry is as follows:

# Job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  *  command to be executed

You can also easily set up cron jobs through the $CRONTAB_SETTINGS environment variable in the docker-compose.yml file. When the container starts, these settings are loaded into crontab, giving you more flexibility to change them later.

services:
  web:
    image: shinsenter/php:8.4-fpm-nginx
    environment:
      ENABLE_CRONTAB: "1"
      CRONTAB_SETTINGS: "* * * * * echo 'This line will run every minute!' | tee /tmp/cron-every-minute.txt"

For more information on environment variables for cron jobs, refer to the Other System Settings section below.

Customize Supervisor command

We can set a $SUPERVISOR_PHP_COMMAND environment variable to the service definition in your application's docker-compose.yml file. This environment variable will contain the command that the container will use to serve your application using another process instead of the default process.

Command Line

docker run \
    -e SUPERVISOR_PHP_COMMAND='php -S localhost:80 index.php' \
    shinsenter/php:8.3

With docker-compose.yml

services:
  web:
    image: shinsenter/php:8.3
    environment:
      SUPERVISOR_PHP_COMMAND: "php -S localhost:80 index.php"

Debug Mode

Enable "debug mode" for more verbose logging by setting DEBUG=1 as an environment variable. This can be used both with docker run and in docker-compose.yml.

Command Line

docker run -e DEBUG=1 shinsenter/php:8.4-fpm-nginx

With docker-compose.yml

services:
  web:
    image: shinsenter/php:8.4-fpm-nginx
    environment:
      DEBUG: "1"

Other System Settings

These Docker images include additional environment variables for fine-tuning container behavior:
