Error running daedalus container - Failed at the daedalus@0.8.0 start script 'cross-env NODE_ENV=production electron ./'.

Hi,
I have troubles running daedalus container which I built from your Dockerfile.
Container is failing with this the error:

cardano-daedalus-docker git:(4fa9492) ✗ docker-compose run daedalus 
WARNING: The DISPLAY variable is not set. Defaulting to a blank string.
Starting cardanodaedalusdocker_cardano-sl_1 ... done

Any idea where the problem might be?

Hi, have you tried to use the start-daedalus script?

Tried with start-daedalus script but does not make any difference.

➜  ~ docker -v    
Docker version 18.01.0-ce, build c97c6d6

I think I tried to pull hcvst/cardano-sl-with-daedalus-wallet from docker registry and I got the same error.

So I managed to find the root cause of my problem. For some reason, DISPLAY environment variable was not propagated into container. Therefore I changed line in docker-compose.yml:

DISPLAY=$DISPLAY

and configured it statically:

DISPLAY=:0.0

After this change, Daedalus UI started without any problem.
