If you work on linux and cannot edit some of the project files right after the first installation, you can run docker compose run --rm php chown -R $(id -u):$(id -g) . to set yourself as owner of the project files that were created by the docker container.
If Symfony is generating an internal redirect for an https:// url, but the resulting url is http://, you have to uncomment the TRUSTED_PROXIES setting in your .env file.
For more details see the Symfony internal redirect documentation.
