Sudden problem with filesystem permissions - chmod -R fails #149
Description
I've been using Monica (4) in Docker for about a year without much difficulty. However, the latest release, or potentially another recent change in docker, seems to have caused a problem.
Upon startup, the entrypoing.sh tries runs chown -R www-data:www-data ${STORAGE} which works find. Then chmod -R g+rw ${STORAGE} fails with a Operation not permitted error for each file. As such, the container never comes up and restarts continually.
To debug, I can enter the (cron) container (that doesn't call entrypoint.sh). As the root user in this shell, I can perform chmod g+rw on individual files. However, using the recursive version chmod -R g+rw on a directory fails (once for each file in the directory). (I find this very strange.)
Adding priveleged: true to the service definition in my docker_compose file "solves" the problem, but I don't like running the container
If it matters, I migrated to the fpm-alpine image about a month ago, but this seems unlikely to be relevant to me. I definitely had fpm-alpine running properly before.
