@ -81,10 +81,29 @@ An example network data:
Some fields are redundant with the port information. We're looking into
simplifying the format, but currently all these fields are mandatory.
You'll need the deployed image to support network data, e.g. by pre-installing
cloud-init_ or Glean_ on it (most cloud images have the former). Then you can
provide the network data when deploying, for example:
.. code-block:: bash
baremetal node deploy <node> \
--config-drive "{\"network_data\": $(cat ~/network_data.json)}"
Some first-boot services, such as Ignition_, don't support network data. You
can provide their configuration as part of user data instead:
.. code-block:: bash
baremetal node deploy <node> \
--config-drive "{\"user_data\": \"... ignition config ...\"}"
