I tried what was suggested in the below discussions and checked the /tmp permissions(PFB)

drwxrwxrwt. 14 root root 360 Apr 27 13:09 tmp
ruby -v
ruby 2.0.0p648 (2015-12-16) [x86_64-linux]

I'm trying to run the container with a non privilege user , should that be an issue ? Cause it worked when I ran it as a root user . However with the current permissions it should work for all users. It'd be really helpful if someone could help me

Thanks
