A common way of interacting with the podman/docker service running on host from within containers is by use of a service socket, which is mounted as a volume to that container (/var/run/podman/podman.sock -> /var/run/docker.sock). Some popular software that makes use of this include Portainer and Traefik.
Debian package of Podman 4.9.3 used to include this, which was enabled by default, however with the introduction of a custom built package it is now missing and any configured containers with the mentioned volume fail to apply after update.
