Answer 1

The Dockerfile looks like the one from the Symfony Github which uses Caddy.

To get that working with Symfony 6.0.1 Download the latest symfony-docker from https://github.com/dunglas/symfony-docker

Then in your terminal window go to the directory where you downloaded the above project run:

SYMFONY_VERSION=6.* docker-compose up --build

This will launch a minimalist skeleton Symfony build using PHP 8, Caddy and Symfony 6.0.1

If you want the website skeleton use

SKELETON=symfony/website-skeleton SYMFONY_VERSION=6.* docker-compose up --build

Answer 2

Have you try to install gd on your docker?

docker-php-ext-install gd

I had this issue 3 years ago, gd and some other package were missing on the docker, we just added them on the docker file.
