I’m using Docker Swarm to launch jupyter notebook services on a worker node. I am using a bind mount to a working directory (/home/user/work), but users can still write to /home/user, which goes to the container’s writable layer. Is there a way limit the size of this writeable layer? I’ve seen references to dm.basesize, but I don’t want to limit the size of the image layer containers. I just want to limit what users can write to their writeable layer.
I know that this layer is deleted when the container is deleted, but if several users write a lot of data here at the same time it will fill up the disk.
I’m running on Centos7, Docker Server Version: 19.03.8, Storage Driver: overlay2
