sshd is not reading authorized_keys file or the HostKeys

[m247support]

Hi,

Thanks a lot for this example! Very useful.. Except that the the the sshd is not reading authorized_keys file or the HostKeys when they mounted as a secret. I have a version k8s v1.8.4 cluster deployed using kubeadm. cating /root/.ssh/authorized_keys seems to follow symlinks to the volume correctly and the file does seem to have the relevant permissions for reading. However, sshd does not seem to be following the symlinks or reading the files at all. Maybe this is a security feature? Thanks in advance!
