ez-php/docker

Docker base image and scaffolding stubs for ez-php modules and projects.

---

Base Image (au9500/php:8.5)

Central PHP runtime image published on Docker Hub. All ez-php modules use it as their base.

Includes:

• PHP 8.5 CLI
• Extensions: pdo_mysql, mbstring, zip, intl, redis, pcov, xdebug
• Composer 2
• Non-root user sail (UID/GID 1000, configurable via build args)
• Dev PHP config (memory_limit = 512M, display_errors = On, xdebug coverage mode)
• Default container-start.sh: runs composer install then sleep infinity

Build locally:

cd modules/docker
docker build -t au9500/php:8.5 .

Build args:

Arg	Default	Description
WWWUSER	1000	UID for the sail user
WWWGROUP	1000	GID for the sail group

Scaffolding (composer require --dev ez-php/docker)

Scaffolds Docker setup for a new module or project by copying stub files into the project root.

Usage

composer require --dev ez-php/docker
vendor/bin/docker-init

Or via Composer script (add to your project's composer.json):

"scripts": {
    "docker:init": "php vendor/ez-php/docker/bin/docker-init"
}

composer docker:init

What gets copied

Stub file	Purpose
Dockerfile	FROM au9500/php:8.5 — minimal module image
docker-compose.yml	App service only
docker-compose.mysql.yml	MySQL service addon (merge as needed)
docker-compose.redis.yml	Redis service addon (merge as needed)
.env.example	Env var template
start.sh	Convenience script: copies .env, starts compose, opens shell
docker/db/create-db.sh	MySQL init script: creates main + testing databases

Existing files are never overwritten — safe to re-run after customisation.

{{MODULE_NAME}} placeholder

The script reads the package name from composer.json and replaces all {{MODULE_NAME}} occurrences. For a package named ez-php/cache, it becomes cache, resulting in container names like ez-php-cache-app.

Combining compose files

For a module that needs MySQL and Redis:

docker compose -f docker-compose.yml -f docker-compose.mysql.yml -f docker-compose.redis.yml up -d

Or merge the relevant services manually into docker-compose.yml.

Module Dockerfile after scaffolding

The generated Dockerfile is intentionally minimal:

FROM au9500/php:8.5

WORKDIR /var/www/html

All extensions, Composer, the sail user, and the default start script are baked into the base image. No COPY instructions needed for common infrastructure.
