Creating an Ironic flavor

1. Create a new flavor called my-baremetal-flavor.

   Note

   The following example sets the CPU architecture for the newly created flavor to be x86_64.

   nova flavor-create ${FLAVOR_NAME} ${FLAVOR_ID} ${FLAVOR_RAM} ${FLAVOR_DISK} ${FLAVOR_CPU}
   nova flavor-key ${FLAVOR_NAME} set cpu_arch=x86_64
   nova flavor-key ${FLAVOR_NAME} set capabilities:boot_option="local"

Note

The flavor and nodes should match when enrolling into Ironic. See the documentation on flavors for more information: http://docs.openstack.org/openstack-ops/content/flavors.html

After successfully deploying the ironic node on subsequent boots, the instance will boot from your local disk as first preference. This will speed up the deployed node's boot time. The alternative, if this is not set, will mean the ironic node will attempt to PXE boot first, which will allow for operator-initiated image updates and other operations. The operational reasoning and building an environment to support this use case is not covered here.
