Analyze shows the temporary files are in docker container web-1, in directories under /var/www/html:

The temporary files are created by the script install-joomla.sh with sed -i in-place substitutes. This could be reproduced by running sed -i inside the container. It is worth to note that this happens on Intel macOS.

Googling shows that the used sed version 4.7 creates a tmp file without any permissions in Docker. This should be fixed in 4.8.

I would create a PR with sedsubstitute in a separate tmp file.

Thanks for the investigation. If you can create a pr, would be nice.
