2.3.3. Manually Tagging the Nodes

After registering and inspecting the hardware of each node, tag them into specific profiles. These profile tags match your nodes to flavors, and in turn the flavors are assigned to a deployment role.

Retrieve a list of your nodes to identify their UUIDs:

$ ironic node-list

To manually tag a node to a specific profile, add a profile option to the properties/capabilities parameter for each node. For example, to tag three nodes to use a controller profile and one node to use a compute profile, use the following commands:

$ ironic node-update 1a4e30da-b6dc-499d-ba87-0bd8a3819bc0 add properties/capabilities='profile:control,boot_option:local'
$ ironic node-update 6faba1a9-e2d8-4b7c-95a2-c7fbdc12129a add properties/capabilities='profile:control,boot_option:local'
$ ironic node-update 5e3b2f50-fcd9-4404-b0a2-59d79924b38e add properties/capabilities='profile:control,boot_option:local'
$ ironic node-update 484587b2-b3b3-40d5-925b-a26a2fa3036f add properties/capabilities='profile:compute,boot_option:local'
$ ironic node-update d010460b-38f2-4800-9cc4-d69f0d067efe add properties/capabilities='profile:compute,boot_option:local'
$ ironic node-update d930e613-3e14-44b9-8240-4f3559801ea6 add properties/capabilities='profile:compute,boot_option:local'

The addition of the profile:compute and profile:control options tag the nodes into each respective profiles.
