how to mount host directories inside a proxmox lxc container

/  4 Comments

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

thats it!

edit: another way, in the same file, as pointed out in the comments is:

lxc.mount.entry: /bkup bkup none bind,create=dir,optional 0 0

This method works with migrations!

Note: Do not put a ‘/’ before the target

People who use pve-zsync or have problems regarding the backup of the container might want to check out this alternative.

    Migration don’t work with this method.

      That’s right, the container is bound to that host with that specific mount path.

    They have a new method of doing this now, fyi:

    This works as of 2015-09-13 using lxc-pve: 1.1.3-1 .
    add this to the .conf file in /etc/pve/lxc
    lxc.mount.entry: /bkup bkup none bind,create=dir,optional 0 0
    Note: Do not put a ‘/’ before the target

      thanks 🙂

      I prefer the original one above because of the easier syntax, though.
