I've just dramatically improved my "Symfony Docker" project.

It now supports Dev Containers, autonomous (YOLO) coding agents such as Claude Code, Xdebug out of the box, instantaneous hot reloading with FrankenPHP, and slim, rootless images for production. 🐘

I presented these features at SymfonyLive Paris. Here is the detailed breakdown and the slides from my talk: https://dunglas.dev/2026/03/coding-at-the-speed-of-thought-the-new-era-of-symfony-docker/

Coding at the Speed of Thought: The New Era of Symfony Docker - Kévin Dunglas

If we want to discuss Developer Experience (DX) in 2026, we have to talk about instantaneous feedback and coding agents. At SymfonyLive Paris 2026, I presented "Coding at the Speed of Thought: Symfony DX in 2026", where I detailed the bleeding-edge features we have brought to the PHP and Symfony ecosystems. To make this vision

@dunglas so it's time to replace symfony docker with something else. Thanks for the heads up 👍
@lukasrotermund Why? All new features are entirely optional and off by default.
@dunglas because of the enAIification. It gets pushed into everything. Even something like symfony docker. Thanks, but no thanks
@lukasrotermund Not sure I'm following you. Symfony Docker has always focused on dev envs setup, and Docker is ideal for safely running coding agents. Use what you like, though!
