Running PHP in Docker containers prevents process spawning

Languages PHP

Hi!

I’m trying to run PHP code inside Docker containers (one way to get around the current limitation of PHP 8.3 not being available, see PHP 8.3 support ), but as soon as the code tries to use symfony/process to spawn new processes, I get a runtime error saying spawning processes is not allowed. This happens when I run composer inside a container (see Travis CI - Test and Deploy with Confidence ) and when I try to run phpstan inside a container (see Travis CI - Test and Deploy with Confidence )

Locally, the containers work fine. Do you have any idea why these errors happen and if I can tweak the Travis/Docker environment to fix it?

PHP 8.3 builds have been operational since end of January.
