## What it is
A Docker Compose-based template and runtime for Symfony applications, bundling FrankenPHP and Caddy with automatic HTTPS, HTTP/3, Mercure real-time messaging, and Xdebug. It provides production, development, and CI-ready configuration that can bootstrap a fresh Symfony project with a single `docker compose up`.

## Use cases
- set up a symfony project with docker
- run php web app locally with https
- docker compose template for symfony production deployment
- local development environment for symfony with xdebug
- host symfony app with automatic tls certificates
- add real-time updates to symfony with mercure
- dev container setup for php coding agents

## When to choose
- starting a new Symfony project that should be Docker-native from day one
- you want automatic HTTPS, HTTP/3, and Early Hints without extra configuration
- you need a slim, rootless production image with FrankenPHP worker mode performance
- you want built-in Mercure real-time messaging and Xdebug support

## When to avoid
- your project uses a framework other than Symfony
- you already have a mature custom Docker setup and only need minor tweaks
- you need a fully managed platform rather than self-managed containers
- you require a license file bundled in the repo before adopting it in a compliance-sensitive context

## Facets
- artifact type: infra-config
- maturity: active
- function: deployment, http-server, web-framework, developer-tools, configuration-management
- domain: web-development, backend, self-hosted
- platform: php, windows, cross-platform
- tags: symfony, frankenphp, caddy, docker-compose, https, mercure, boilerplate, dev-container, xdebug, http3, devops, containers, docker, linux, macos
