Open Stack

We need to be highly security conscious here doing this in an insecure
manner is a HUGE risk so rsync over ssh from the master node is usually (or
scp) OK but rsync protocol from the node in the cluster will not be BAD (it
leaves the certs exposed on an weak service.)

I could see this being implemented as some additional task type that can
instead be run on the fuel master nodes instead of a target node. This
could also be useful for plugin writers that may need to access some
external API as part of their task graph. We'd need some way to make the
generate task run once for the env, vs the push certs which runs for each
role that has a cert requirement.

we'd end up with some like
generate_certs:
  runs_from: master_once
  provider: <whatever>
push_certs:
  runs_from: master
  provider: bash
  role: [*]
