Hello everyone,
I am trying to build my container using the ue4-docker image and I want to run the Editor of the Unreal project using ue4 run
My Dockerfile looks like below:
FROM adamrehn/ue4-full:custom AS builder
COPY --chown=ue4:ue4 . /tmp/project
WORKDIR /tmp/project
RUN ue4 build
RUN ue4 run
And the image build always fail at ue4 run command with the following error messages:
Info: I have already tried locally executing .uproject file and it can open the unreal editior. I would like to know why I cannot do it in the docker container.

------
Dockerfile:7
--------------------
5 | WORKDIR /tmp/project
6 | RUN ue4 build
7 | >>> RUN ue4 run
8 |
9 | FROM adamrehn/ue4-runtime:latest
--------------------
ERROR: failed to solve: process "/bin/sh -c ue4 run" did not complete successfully: exit code: 1
I also tried this: build the container image without RUN ue4 run in Dockerfile. And after successfully built the image and run the container, I tried to run ue4 run in the container and got the same error message.
Could someone help please? It is a rather urgent problem. Thanks a lot for your help in advance!
