[SOLVED] LXC Container Config Overwritten on Container Restart

[begleysm]

I'm attempting to mount a host directory in a container as per my other thread @ (https://forum.proxmox.com/threads/expose-cifs-share-to-lxc-container.44757/#post-213868).

I am able to get this to work by modifying the container config file. Specifically I'm adding something like

lxc.mount.entry = /mnt/share /var/lib/lxc/103/rootfs/mnt/share none bind 0 0
lxc-mount​

to the bottom of config file at /var/lib/lxc/103/config

When I modify this file and start the Container everything works!

Now, my problem is, when I shutdown the Container, start it, and then go view /var/lib/lxc/103/config I find that the two lines I added to the bottom are gone!

How/where do I modify the container config where it will persist through restarts?

/etc/pve/lxc/<ctid>.conf But I suggest to use normal container mount point syntax instead of low level lxc configs.

Thanks dietmar! I found that config file location but sorta dismissed it because the format didn't match what I was seeing at /var/lib/lxc/103/config.

Regarding using "normal container mount point syntax" I wasn't familiar with this syntax but did a little googling and found the "Bind Mount Points" section of the "Linux Container" page on the Proxmox Wiki. (https://pve.proxmox.com/wiki/Linux_Container#_bind_mount_points).

I added this line to the bottom of /etc/pve/lxc/103.conf and it worked!

mp0: /mnt/share,mp=/mnt/share
