Public bug reported: - [x] This is a doc addition request.
The admin configuration for hypervisors does not have a subpage with details about configuring nova with the ironic compute driver. There are at least a few things that could go into a page like that: * Summary of what it does and how it interacts with the ironic service as a 'hypervisor'. Some of that information is available in the ironic docs, e.g.: https://docs.openstack.org/ironic/latest/install/get_started.html?highlight=nova #interaction-with-openstack-components Since it comes up from time to time, I would also mention that the ironic driver is the only one in nova where the compute_nodes table record is 1:M with the compute services table record for the given host, meaning a nova-compute service can manage multiple ComputeNodes, and the ComputeNodes for the ironic driver managed compute service uses the ironic node uuid for the compute node hypervisor_hostname (nodename) and uuid fields. And ironic node : compute node : instance are 1:1:1. This is more contributor/reference information but it's worth mentioning somewhere since it's kind of tribal knowledge in nova. * Ironic-specific configuration: https://docs.openstack.org/nova/latest/configuration/config.html#ironic - This could also include things like configuring baremetal flavors: https://docs.openstack.org/ironic/latest/install/configure-nova- flavors.html - Running multiple nova-computes in HA mode managing the same set of nodes: https://specs.openstack.org/openstack/nova- specs/specs/newton/implemented/ironic-multiple-compute-hosts.html * Scaling and performance issues.
