Symfony Docker

A Docker-based installer and runtime for the Symfony web framework, with FrankenPHP and Caddy inside!

Specially tailored for coding agents: ships with a Dev Container configuration that lets Claude Code (and other AI coding assistants) run in fully autonomous mode inside a sandboxed environment.

CI

Getting Started

  1. If not already done, install Docker Compose (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
  5. Run docker compose down --remove-orphans to stop the Docker containers.

Features

Enjoy!
