PHP Base Image

An enhanced version of the default PHP Docker image which can install PHP extensions without requiring manual dependency installation using mlocati/docker-php-extension-installer and installs a default nginx setup.

Pull Command

The following command will retrieve an image with PHP 8.1 and Composer v2:

docker pull ghcr.io/clevyr/php:8.1

Alternative tags exist with Composer v1. If your application still requires Composer v1, you may add the version to the end of the tag:

docker pull ghcr.io/clevyr/php:8.1-composer1

Runtime Configuration

The following variables can be configured at build (Typically with an ARG in the Dockerfile) or during runtime (With environment variables).

PHP Configuration

Some php.ini values can be configured as a build arg.

Build Arg	Description	Default
PHP_MAX_EXECUTION_TIME	See max_execution_time.	30
PHP_MAX_INPUT_VARS	See max_input_vars.	1000
PHP_MEMORY_LIMIT	See memory_limit.	256M
PHP_POST_MAX_SIZE	See post_max_size.	32M
PHP_UPLOAD_MAX_FILESIZE	See upload_max_filesize.	8M
PHP_MAX_FILE_UPLOADS	See max_file_uploads.	20

PHP-FPM Configuration

Environment Variable	Description	Default
PHP_FPM_PM_MAX_CHILDREN	See pm.max_children.	80
PHP_FPM_PM_START_SERVERS	See pm.start_servers.	2
PHP_FPM_PM_MIN_SPARE_SERVERS	See pm.min_spare_servers.	1
PHP_FPM_PM_MAX_SPARE_SERVERS	See pm.max_spare_servers.	3
PHP_FPM_PM_MAX_REQUESTS	See pm.max_requests.	0

Build Arguments

The following variables can be only be configured at build.

Build Arg	Description
INSTALL	PHP extensions to install. See here for available extensions.
DEPS	apk dependencies to install during the build.

Nginx Configuration

Some nginx values can be configured as a build arg.

Build Arg	Nginx Directive	Default
NGINX_ROOT	root	/app/public

Legacy Build Arguments

These are the legacy build args. They will still be supported for the forseeable future, but they are not as powerful as the new INSTALL build arg, so if you are creating an app from scratch, the INSTALL build arg may be more useful for you. These are also convenient because they group up some extensnions. For example, if you set INSTALL_MYSQL=true, then both mysqli and pdo_mysql will be installed.

Build Arg	Default
INSTALL_BCMATH	true
INSTALL_CALENDAR	false
INSTALL_EXIF	false
INSTALL_GD	true
INSTALL_IMAGICK	false
INSTALL_INTL	false
INSTALL_PCNTL	false
INSTALL_MOSQUITTO	false
INSTALL_MYSQL	false
INSTALL_PGSQL	true
INSTALL_REDIS	false
INSTALL_XDEBUG	false
INSTALL_ZIP	false
