This article describes how to mount a Network Share inside a Linux Container (LXC). This is non-trivial because LXC Containers do not have the privileges available to directly mount network locations. The work around involves mounting the network share on the Container Host and then binding the mount folder on the host to a folder in the Container.

1. Log into your Container as root
   1. Create the a mount point directory with

      mkdir /mnt/extfolder

   2. Log out of the container and stop the container
2. Log into your Host Machine as root
   1. if necessary, create a credentials file with the username and password for your network share. Then secure the file

      nano /root/.credentials/my-credentials

      1. add the following lines

         username=theusername
         password=thepassword
         workgroup=theworkgroup

      2. Exit nano and save your changes by hitting Ctrl-X and then Y
   2. run

      chmod 600 /root/.credentials/my-credentials

   3. create the target mount folder by running

      mkdir /mnt/netfolder

   4. Add a line to your fstab file to mount the network share by running

      nano /etc/fstab

      and adding the following line to the bottom

      //net/path/to/netfolder /mnt/netfolder cifs user,credentials=/root/.credentials/my-credentials,iocharset=utf8,noperm 0 0

   5. Bind the host directory to the container directory in the container config by running

      nano /etc/pve/nodes/hostname/lxc/mycontainer.conf

      and adding the following line after memory and before net0

      mp0: /mnt/netfolder,mp=/mnt/extfolder

3. Restart the client and the network share should be accessible at /mnt/extfolder
