But I am able to use the UE4editor from exported copy of Engine on host machine and it runs fine.

Okay, testing a fresh build of the ue4-full image with the change from e162eda shows the Editor windows appearing successfully on the host display when rendering with Vulkan. My apologies for the oversight in the Dockerfile @jaybhanushali99 @quentingllmt @petergerten.
