I have docker running with several containers using docker compose, however none of them show in the Symfony toolbar:
image

Also running symfony var:export --debug --multiline doesn't list any docker containers, nor env variables that should have been set by docker.

Maybe the issue is docker-side, but I have no idea how to further diagnose the problem.
I'm running Docker Desktop.
/opt/docker-desktop/bin/com.docker.diagnose check shows no fatal errors

Could it be related to #285 (DOCKER_HOST env var issue)?

Indeed it was, thank you!

Adding export DOCKER_HOST=unix://$HOME/.docker/desktop/docker.sock in my .bashrc fixed the problem.
There should really be at least some indication of the problem, like an error message that docker.sock is not found when you run symfony var:export --debug maybe with a suggestion why.

The socket detection path is not part of the Symfony CLI code but directly Docker's one. I'll see what we can do but as stated previously, Docker explicitly says that in such case one has to export DOCKER_HOST so I'm not sure I can do it so easily 😕

Regarding the --debug flag: the debug information are already showed when one using the -vvv flag, but it's true this flag documentation is mentioning "Debug Docker support" so I'll look into it.
