# Symfony Docker

A [Docker](https://www.docker.com/)-based installer and runtime for the [Symfony](https://symfony.com) web framework,
with [FrankenPHP](https://frankenphp.dev) and [Caddy](https://caddyserver.com/) inside!

Specially tailored for coding agents: ships with a [Dev Container](https://containers.dev/) configuration
that lets [Claude Code](https://claude.ai/claude-code) (and other AI coding assistants) run in fully autonomous
mode inside a sandboxed environment.

![CI](https://github.com/dunglas/symfony-docker/workflows/CI/badge.svg)

## Getting Started

1. If not already done, [install Docker Compose](https://docs.docker.com/compose/install/) (v2.10+)
2. Run `docker compose build --pull --no-cache` to build fresh images
3. Run `docker compose up --wait` to set up and start a fresh Symfony project
4. Open `https://localhost` in your favorite web browser and [accept the auto-generated TLS certificate](https://stackoverflow.com/a/15076602/1352334)
5. Run `docker compose down --remove-orphans` to stop the Docker containers.
