I'm adding [Heat] to the subject. After some discussion on IRC it seems
that what we need to do with Heat is not totally straightforward.
Here's an attempt at a brief summary:
In TripleO we deploy OpenStack using Heat, the cloud is described in a
Heat template . We want to externally generate and then upload 3
small binary files to the controller nodes (Keystone PKI key and
certificates ). We don't want to generate them in place or scp them
into the controller nodes, because that would require having ssh access
to the deployed controller nodes, which comes with drawbacks .
It would be good if we could have the 3 binary files put into the
controller nodes as part of the Heat stack creation. Can we include them
in the template somehow? Or is there an alternative feasible approach?
