Fast-Track Deployment

Fast track is a mode of operation where the Bare Metal
service keeps a machine powered on with the agent running between
provisioning operations. It is first booted during in-band inspection or
cleaning (whatever happens first) and is only shut down before rebooting
into the final instance. Depending on the configuration, this mode can
save several reboots and is particularly useful for scenarios where
nodes are enrolled, prepared and provisioned within a short period of
time.

Warning

Fast track deployment targets standalone use cases and is only tested
with the noop networking. The case where inspection,
cleaning and provisioning networks are different is not supported.

Note

Fast track mode is very sensitive to long-running processes on the
conductor side that may prevent agent heartbeats from being
registered.

For example, converting a large image to the raw format may take long
enough to reach the fast track timeout. In this case, you can either
use raw
images <stream_raw_images>
or move the conversion to the
agent side with:

[DEFAULT]
force_raw_images = False

Enabling

Fast track is off by default and should be enabled in the
configuration:

[deploy]
fast_track = true

Starting with the Yoga release series, it can also be enabled or
disabled per node:

baremetal node set <node> --driver-info fast_track=true

Inspection

If using in-band inspection, you need to tell ironic-inspector
not to power off nodes afterwards. Depending on the inspection mode
(managed or unmanaged), you need to configure two places. In
ironic.conf:

[inspector]
power_off = false

And in inspector.conf:

[processing]
power_off = false

Finally, you need to update the inspection PXE
configuration <install/index.html#configuration>
to include
the ipa-api-url kernel parameter, pointing at the
ironic endpoint, in addition to the existing
ipa-inspection-callback-url.
