This helps with routing of TCP traffic between clients and servers in case flannel or similar service is not installed and pods don't see each other. - It needs 'insecure' in /etc/exports to allow NFS clients on ports > 1024, Kubernetes service will change client port to a random number. - glusterfs no longer needs explicit endpoint definition, it uses the service instead.
NFS server container for testing
This container exports '/' directory with an index.html inside. NFSv4 only.
Inspired by https://github.com/cpuguy83/docker-nfs-server.
Used by test/e2e/* to test NFSVolumeSource. Not for production use!
