5.3. Tagging Nodes into Profiles
After registering and inspecting the hardware of each node, you will tag them into specific profiles. These profile tags match your nodes to flavors, and in turn the flavors are assigned to a deployment role. Default profile flavors
compute, control, swift-storage, ceph-storage, and block-storage are created during Undercloud installation and are usable without modification in most environments.
Note
For a large number of nodes, use automatic profile tagging. See Appendix C, Automatic Profile Tagging for more details.
To tag a node into a specific profile, add a
profile option to the properties/capabilities parameter for each node. For example, to tag your nodes to use Controller and Compute profiles respectively, use the following commands:
ironic node-update 58c3d07e-24f2-48a7-bbb6-6843f0e8ee13 add properties/capabilities='profile:compute,boot_option:local' ironic node-update 1a4e30da-b6dc-499d-ba87-0bd8a3819bc0 add properties/capabilities='profile:control,boot_option:local'
$ ironic node-update 58c3d07e-24f2-48a7-bbb6-6843f0e8ee13 add properties/capabilities='profile:compute,boot_option:local'
$ ironic node-update 1a4e30da-b6dc-499d-ba87-0bd8a3819bc0 add properties/capabilities='profile:control,boot_option:local'
The addition of the
profile:compute and profile:control options tag the two nodes into each respective profiles.
These commands also set the
boot_option:local parameter, which defines the boot mode for each node.
Important
The director currently does not support UEFI boot mode.
After completing node tagging, check the assigned profiles or possible profiles:
