Docker not working with Debian 12

Docker Engine Compose
1

I’m currently studying Ansible with a Udemy course (“Dive Into Ansible - Beginner to Expert in Ansible - DevOps”) that works with Docker instances; I installed Docker CE and Docker Compose plugin towards that end.

Upon spinning up the Linux images with docker compose up, my networking (wifi), Bluetooth, and pulseaudio capabilities went offline on my Debian 12 install. Wifi returned upon shutting down the instances, and I was able to restart the audio via systemctl - however, I had to reboot the system to regain Bluetooth capabilities.
System is a Lenovo IdeaPad Slim 5,
Kernel is 6.12.12+bpo-amd64
RAM: 16GB
CPU cores: 12 - 13th Gen Intel i7

I couldn’t find anything in the logs - and checking online (as well as Ansible and Docker forums) showed no information on how to resolve the issue. Has anyone been able to get Docker and Docker Compose to successfully work with Debian 12?

Well, it depends on what images and what security settings you used. If you give the containers full access to host (which is not the default), then they could mess up the host system.

As already said, it depends on what image you are using and how you start the container, but if you need a guess (the best we can do without more info) running Systemd in a container can break the host if done wrong. Normally it shouldn’t be done at all of course.
