feature: flexvolume

[v1k0d3n]

i might be able to even get to this at some point, but it would be nice to enable flexvolumes for kubernetes during installation. i've been working with coreos bare metal this weekend, and torus. here are some useful docs:

flexvolumes (kubernetes):
https://github.com/kubernetes/kubernetes/blob/release-1.2/examples/flexvolume/README.md

torus (coreos):
https://github.com/coreos/torus/tree/master/contrib/kubernetes#installing-the-torus-flexvolume-plugin-on-generic-kubernetes-installations

for most OS flavors, it wouldn't be too hard to write to /usr/libexec/kubernetes/kubelet-plugins/, but this is an issue for CoreOS. kubespray could possibly work around this during installation, but i'll have to dig a little deeper (my experience is only surface deep at the moment).

+1 I've also played with torus and more generaly it would be nice to handle plugins with kargo

[v1k0d3n]

i agree. i am getting the following error (and not finding much resolution). i may have to reach out to those guys for more detail:

Unable to mount volumes for pod "postgres-torus-1754447054-uf809_default(e30e6b13-3bda-11e6-afba-001fc69b97d0)": attach command failed, status: Failure, reason: Unit torus-dev-nbd0.service already exists.

this was when using their example docs for postgres.

Yes that would be awesome if kargo could handle torus and more generally flexvolumes

Is there any news on this issue?

I am not sure, however I found some progress on that issue here: https://github.com/kubernetes-incubator/kubespray/pull/2132/files

as pointed by @perunb
it seems fixed by #2132
