I created an LXC container and stored files there. How do I share this containers storage with another lxc container?

Of course I could create a network share, but that would create unnecessary network traffic.

Easiest way I found was using a directory on the host and adding that directory as mount point to all containers that need access to those files.
Other options are using network file sharing such as NFS or CIFS but you have to setup a server or file sharing service.

PS: I just gave you some options and only told you what worked best for me. Maybe other people have better ideas for your specific situation. Do what you think is best for you...

so I have a ZFS volume that is ~9 TB. I created a container on that volume that hosts docker. then that docker. all the files are stored in the lxc docker container that i share out to my docker images. are you saying that I should transfer them out and retransfer them back to the host (proxmox) itself? How do I create a folder on that ZFS volume? Just through the CLI?

retransferring everything would be a pain and then dealing with 3 levels of permissions (host, lxc, docker). is there no simple way that won't saturate network with unnecessary traffic?
