standard_init_linux.go:211: exec user process caused "permission denied"

[ArundathiGV]

Note: This issue persist only with ubuntu 18.04.1. When using ubuntu 16.04 everything works without any issue

When trying to run gcr.io/google_containers/defaultbackend as non root, the pod goes to crashLoopBackOff state when I see the below error in logs
