Importing Nodes From a File
===========================
You can import nodes into Warewulf by using the ``wwctl node import`` command. The
file used must be in YAML or CSV format.
You can import nodes into Warewulf by using the ``wwctl node import`` command.
The file used must be in YAML format.
.. warning::
Importing a node configuration will fully overwrite the existing settings,
including any customizations not present in the import file. If the node
already exists and you wish to update it, ensure that the import file
includes all the options you want to retain.
CSV Import
----------
.. note::
As of Warewulf v4.6.1, the csv import functionality is broken and an
`issue <https://github.com/warewulf/warewulf/issues/1862>`_
has been created to track this.
The CSV file must have a header where the first field must always be the nodename,
and the rest of the fields are the same as the long commandline options. Network
device must have the form ``net.$NETNAME.$NETOPTION``. (e.g., ``net.default.ipaddr``).
Tags are currently not supported and must be added separately after the import.
As an example, the following CSV file:
.. code-block:: csv
nodename,net.default.hwaddr,net.default.ipaddr,net.default.netmask,net.default.gateway,discoverable,image
n1,00:00:00:00:00:01,10.0.2.1,255.255.255.0,10.0.2.254,false,rockylinux-9
This can be imported with the following command:
.. code-block:: shell
wwctl node import --csv /path/to/nodes.csv
YAML Import
-----------
The YAML file must be a mapping of node names to their attributes, where each node is represented as a dictionary of attributes.
To simplify the creation of the YAML file, you can use the wwctl node export command to export the current node configuration to a YAML file.
This exported file can serve as a template for creating new nodes.
