Deploy OpenStack host with Ironic and Redfish

Define node variables

NODE=com4-dev
NODE_BMC_HOST=com4-dev.ipmi.dev.i.example.com
NODE_MAC_NIC1=00:11:22:33:44:55

Define env variables

NODE_BMC_USER=ADMIN
NODE_BMC_PASS=ADMIN

Create now node with Redfish (pxe device boot broken)
https://docs.openstack.org/ironic/latest/admin/drivers/redfish.html

openstack baremetal node create \
  --name ${NODE} \
  --driver redfish \
  --driver-info redfish_address="https://${NODE_BMC_HOST}" \
  --driver-info redfish_username=${NODE_BMC_USER} \
  --driver-info redfish_password=${NODE_BMC_PASS} \
  --driver-info redfish_verify_ca=false \
  --driver-info redfish_system_id=/redfish/v1/Systems/1

Create now node with IPMI
https://docs.openstack.org/ironic/latest/admin/drivers/ipmitool.html

openstack baremetal node create \
  --name ${NODE} \
  --driver ipmi \
  --driver-info ipmi_address=${NODE_BMC_HOST} \
