Exposing a directory on the host machine to an LXC container

1. Log into the container and create an empty directory, this will be the mount point
2. Log out and stop the container.
3. Open to your container's config file
   • For regular LXC containers: /var/lib/lxc/mycontainer/config
   • For unprivileged LXC containers: $HOME/.local/share/lxc/mycontainer/config
4. Add a new line above the lxc.mount directive, that follows the format below. Substitute proper paths as necessary:
   • lxc.mount.entry = /path/to/folder/on/host /path/to/mount/point none bind 0 0

• Both of these paths are relative to the host machine.
