For that you have to mount the container-tmp directory to your host-tmp directory. Sure, it helps, but it sounds like a nasty workaround to me. Same as my solution: docker container exec sabnzbd chmod 777 /tmp docker container exec mariadb chmod 777 /tmp ... If I run the same images on my workstation with docker(-compose), I don't have such problems.

Same goes for me. It's a real pain ... After each restart I have to change the permissions of /tmp and /var/tmp for ~7 containers.
