Bare metal Standard with Ironic R2.0¶
Overview¶
Ironic is an OpenStack project that provisions bare metal machines. For information about the Ironic project, see Ironic Documentation.
End user applications can be deployed on bare metal servers (instead of virtual machines) by configuring OpenStack Ironic and deploying a pool of 1 or more bare metal servers.
Figure 1: Standard with Ironic deployment configuration¶
Bare metal servers must be connected to:
IPMI for OpenStack Ironic control
ironic-provisioning-net tenant network via their untagged physical interface, which supports PXE booting
As part of configuring OpenStack Ironic in StarlingX:
An ironic-provisioning-net tenant network must be identified as the boot network for bare metal nodes.
An additional untagged physical interface must be configured on controller nodes and connected to the ironic-provisioning-net tenant network. The OpenStack Ironic tftpboot server will PXE boot the bare metal servers over this interface.
Note
Bare metal servers are NOT:
Running any OpenStack / StarlingX software; they are running end user applications (for example, Glance Images).
To be connected to the internal management network.
Installation¶
StarlingX currently supports only a bare metal installation of Ironic with a standard configuration, either:
Bare metal Standard with Controller Storage Installation R2.0
Bare metal Standard with Dedicated Storage Installation R2.0
This guide assumes that you have a standard deployment installed and configured with 2x controllers and at least 1x compute node, with the StarlingX OpenStack application (stx-openstack) applied.
