webdevops/php¶
The php images are based on webdevops/base-app
with PHP cli and PHP-FPM. PHP-FPM is running on port 9000.
Uses Supervisord
This image is using supervisor and runs the daemon under user application
(UID 1000; GID 1000) as default. If the container is
started under a different user the daemon will be run under the specified uid.

You can specify a comma-separated list of unwanted modules as dynamic env variable PHP_DISMOD
, e.g. PHP_DISMOD=ioncube,redis
.
PHP.ini variables¶

as dynamic env variable which will set memory_limit = 256M
as php setting.

---|---|---|
php.{setting-key} |
Sets the {setting-key} as php setting |

PHP FPM variables¶
You can specify eg. fpm.pool.pm.max_requests=1000
as dyanmic env variable which will sets pm.max_requests = 1000
as fpm pool setting.
The prefix fpm.pool
is for pool settings and fpm.global
for global master process settings.
Environment variable | Description | Default |
---|---|---|
fpm.global.{setting-key} |
Sets the {setting-key} as fpm global

Composer¶
Due to the incompatibilities between composer v1 and v2 we introduce a simple mechanism to switch between composer versions.
Environment variable | Description | Default |
---|---|---|
COMPOSER_VERSION |
Specify the composer version to use | 2 |
Be aware that this switch is only executed during container start (entrypoint). If you want to build your software with a specific composer version, you can do this:
FROM webdevops/php-nginx:7.3
COPY ./src /app
RUN composer1 install -d /app
Or composer
respectively.
Customization¶
PHP customization¶
For customization a placeholder /opt/docker/etc/php/php.ini
is available which will be loaded as last
configuration file. All settings can be overwritten in this ini file.
Either use COPY
inside your Dockerfile
to overwrite this file or use
RUN echo memory_limit = 128 M >> /opt/docker/etc/php/php.ini
to set specific php.ini values.
