问题
I'm building docker images from Dockerfile and when I run a script(CUDA installation script) which has
echo XXX > /dev/tty
in it, then an error "/dev/tty: No such device or address" comes up and the build failed. I've tried --silent flag but it seems do no help.
My base image is Cent OS 7.
Is there anyway to fix or work around this?

I've fixed this problem: it turns out I didn't install command tar & perl before hand. And the script wants to write error messages to /dev/tty. The error information led me to the wrong way to solve this issue.
Thanks.
