3 variants of PHP7 from Debian :
- composer: bearstech/php-composer
- cli: bearstech/php-cli
- fpm: bearstech/php
All variants are available as tag for PHP 7.0, 7.1, 7.2 and 7.3
Dockerfiles are available at https://github.com/factorysh/docker-php
docker run --rm bearstech/php:7.3
docker run --rm bearstech/php-cli:7.3
docker run --rm bearstech/php-composer:7.3
In bearstech/php-composer images, composer is the latest stable version : 2.x now.
The composer1 command is here to help your migration to Composer 2, composer1 version 1.10.x.
fpm images needs a specific user, not root.
In your Dockerfile, use something like :
RUN useradd alice --shell /bin/bash
COPY www /var/www/web
USER alice
If you are using a volume, be carefuls with uids :
ARG UID=1001
RUN useradd alice --uid ${UID} --shell /bin/bash
COPY www /var/www/web
USER alice
and build the image with a build-arg like :
--build-arg UID=`id -u`
Default session handler is a file.
If you set SESSION_REDIS_URL, the will use Redis as a session handler.

All php images implements the concept of entrypoint.d.
With entrypoint.d user can trigger custom actions before application startup
(entrypoint).
Just put your scripts and executable in the /entrypoint.d directory of your php
containers. On startup, each executable file inside this directory will be
run in an independent bash process.
Entrypoint.d runs files marked as executable, in alphabetical order. You can look
for an example inside /entrypoint.d
Since each container runs entrypoint.d scripts, this is not the
recommanded way to run migrations :
if you have N replicas, migrations will be run N times
