Permission issue on docker container

[seonho]

I followed the setup guide on docker container.

And finally I got a following message.

root@01e7a29facb9:/# guild check
guild_version:          0.1.1
guild_home:             /opt/guild_0.1.1_linux_x86_64/lib/guild
Not allowed to run as root without setting effective user (-user option)!

My docker image is based on TensorFlow docker image.

Seems like erlexec doesn't like when you want it to spawn OS process when BEAM runs as root.
