This talk provides an in-depth, technical discussion of how OpenShift clusters are created. Beginning with the design of the installer and following an installation linearly, the talk explains how the installer uses a directed-acyclic asset graph to generate resources required for a cluster, bundles those resources into ignition, creates cloud infrastructure using cluster-api, and depends on cluster operators to complete installation. This talk will also explain the recent replacement of Terraform with cluster-api controllers.
