Vulkan not working inside LXC container with NVIDIA graphics card

I've been trying to get a gpu passthrough to my lxc container, so far Xorg and OpenGL work but vulkan doesn't

I have installed

nvidia nvidia-utils vulkan-icd-loader vulkan-tools

If I run vulkaninfo it fails with:

error: XDG_RUNTIME_DIR not set in the environment.
ERROR at /build/vulkan-tools/src/Vulkan-Tools-1.2.194/vulkaninfo/vulkaninfo.h:248:vkGetPhysicalDeviceSurfacePresentModesKHR failed with ERROR_UNKNOWN

Here's my lxc container config file:

# Distribution configuration
lxc.include = /usr/share/lxc/config/common.conf
lxc.include = /usr/share/lxc/config/userns.conf
lxc.arch = x86_64
