Research direction

Start by reviewing the linked Red Hat documentation for pre-provisioned nodes and the issue's four stated requirements. Trace the existing InfraRed deployment entry points for repository setup, os-collect-config, SSH keying, and Heat templates; the work is done when predeployed Overcloud servers can be deployed without Ironic provisioning.

Written by the indexing model from the issue text.

Description

As far as I can tell, InfraRed does not have full support for helping setup predeployed/preprovisioned nodes. This can greatly speed up deployment time and lowers the complexity by skipping the Ironic provisioning entirely.

This entails:

  • Enabling TripleO/RHOSP repositories on the Overcloud nodes.
  • Installing and setting up os-collect-config for Heat on the Overcloud nodes (only for non-config-download deployments).
  • Keying the stack user from the Undercloud to access a sudo-privileged user on the Overcloud nodes. It can be keyed to any user but the documentation suggests stack.
  • Using predeployed server Heat templates.
