Proxmox supports the creation of custom mountpoints inside a lxc container straight from the proxmox container .conf file:
locate your container conf file under /etc/pve/lxc/<ID>.conf and add the following:
mp0:/mount/point/on/host,mp=/mount/point/on/lxc
mp1:/another/mount/point/on/host,mp=/another/mount/point/on/lxc
Reboot
thats it!
