Docker is not recognizing a directory as directory in Arch Linux
The image used expects a directory at /etc/timezone that is not used on Arch Linux.
Expected /etc/timezone contents example:
Etc/UTCSimply remove that bind mount from your command or docker-compose file. You need to set the timezone at in the container differently or find a way to keep the /etc/timezone file in sync with /etc/localtime.
/etc/timezone is a Solaris and Debian thing, I guess. It expects the timezone as a pair
