Output: mount.nfs: Failed to resolve server foo-secogke-bar-vm: Temporary failure in name resolution

Using the IP addresses instead of the names in the biokepi-machine works (requires coclobas fixed for IP addresses → https://github.com/hammerlab/coclobas/commit/44377724ae6e463a0a4ece052f580d98ec2a1e16).

Should we always find and put the IP addresses?

OK, this seems reproducible and due to the default VM used by Kubernetes:

with Coclobas options:

 "--gke-image-type"; "container_vm";

everything works fine, but with COS it doesn't.

cf. also https://github.com/hammerlab/coclobas/issues/58

@smondet: weird - didn't have that issue when I was testing it earlier. Wonder what was different, but thanks for looking into this!

Just a couple of notes:

on the G-Groups forum on Feb 23:

We are currently working on it and will give an update soon.

I was really eager to try the new images out since I was hoping that would resolve some of the weird issues that we have been facing but looks like every new feature/image is followed by other new bugs/issues related to that.
