Hello,
I’m trying to switch an unprivileged container working perfectly with X to Wayland. (I am using lxc 3.0.0 and Plasma)
So, I adapted my config as follows:
#lxc.mount.entry = /tmp/.X11-unix mnt/X11-unix tmpfs bind,none,create=dir 0 0
lxc.mount.entry = /run/user/1001/wayland-0 tmp/wayland-0 none bind,ro,create=file
Alas, during the start, I encountered the following error :
lxc-start steam 20191103110640.437 ERROR utils - utils.c:safe_mount:1187 - Permission denied - Failed to mount "/run/user/1001/wayland-0" onto "/usr/local/lib/lxc/rootfs/tmp/wayland-0"
lxc-start steam 20191103110640.437 ERROR conf - conf.c:mount_entry:2044 - Permission denied - Failed to mount "/run/user/1001/wayland-0" on "/usr/local/lib/lxc/rootfs/tmp/wayland-0"
On the host, I have got user id 1001.
[uu@host1 ~] ls -l /run/user/1001/wayland-0
srwxr-xr-x 1 uu uu 0 3 nov. 11:53 /run/user/1001/wayland-0
What’s happened ? Any suggestion is welcome.

A temporary ugly workaround :
[uu@host ~] sudo chmod 757 /run/user/1001
My user uu is 1001 on host and 1000 on my unprivileged container.

So sharing just the Wayland socket (no Xwayland required) you can get the container apps to show up on the host.
While Wayland-only distro are you using?

I’m using ArchLinux, both on host and container. For the moment, I can’t do without Xwayland. In any case, I have not tried to do without it.

If you are using Xwayland, why would you need to expose the Wayland Unix socket to the container?

I’m not capable answering you. I can just say, under wayland I don’t have any X11 socket (/tmp/.X11-unix/X0) and not mounting the wayland socket, avoid me starting any gui app. Not sure I am answering your question.
