Local boot with partition images
Starting with the Kilo release, Bare Metal service supports local boot with partition images, meaning that after the deployment the node's subsequent reboots won't happen via PXE or Virtual Media. Instead, it will boot from a local boot loader installed on the disk.
It's important to note that in order for this to work the image being
deployed with Bare Metal service must contain
grub2
installed within it.
Enabling the local boot is different when Bare Metal service is used with Compute service and without it. The following sections will describe both methods.
Note
The local boot feature is dependent upon a updated deploy ramdisk built with diskimage-builder version >= 0.1.42 or ironic-python-agent in the kilo-era.
Enabling local boot with Compute service
To enable local boot we need to set a capability on the bare metal node, for example:
ironic node-update <node-uuid> add properties/capabilities="boot_option:local"
Nodes having boot_option
set to local
may
be requested by adding an extra_spec
to the Compute service
flavor, for example:
nova flavor-key baremetal set capabilities:boot_option="local"
Note
If the node is configured to use UEFI
, Bare Metal
service will create an EFI partition
on the disk and switch
the partition table format to gpt
. The
EFI partition
will be used later by the boot loader (which
is installed from the deploy ramdisk).
Enabling local boot without Compute
Since adding capabilities
to the node's properties is
only used by the nova scheduler to perform more advanced scheduling of
instances, we need a way to enable local boot when Compute is not
present. To do that we can simply specify the capability via the
instance_info
attribute of the node, for example:
ironic node-update <node-uuid> add instance_info/capabilities='{"boot_option": "local"}'
