Enrolling a node
----------------
In the Liberty cycle, starting with API version 1.11, the Bare Metal service
added a new initial provision state of ``enroll`` to its state machine.
Existing automation tooling that use an API version lower than 1.11 are not
affected, since the initial provision state is still ``available``.
However, using API version 1.11 or above may break existing automation tooling
with respect to node creation.
The default API version used by (the most recent) python-ironicclient is 1.9.
The examples below set the API version for each command. To set the
API version for all commands, you can set the environment variable
``IRONIC_API_VERSION``.
API version 1.10 and below
..........................
Below is an example of creating a node with API version 1.10. After creation,
the node will be in the ``available`` provision state.
Other API versions below 1.10 may be substituted in place of 1.10.

API version 1.11 and above
..........................
Beginning with API version 1.11, the initial provision state for newly created
nodes is ``enroll``. In the examples below, other API versions above 1.11 may be
substituted in place of 1.11.

+--------------------------------------+--------+---------------+-------------+--------------------+-------------+
In order for nodes to be available for deploying workloads on them, nodes
must be in the ``available`` provision state. To do this, nodes
created with API version 1.11 and above must be moved from the ``enroll`` state
to the ``manageable`` state and then to the ``available`` state.
To move a node to a different provision state, use the
``node-set-provision-state`` command.
.. note:: Since it is an asychronous call, the response for
``ironic node-set-provision-state`` will not indicate whether the
transition succeeded or not. You can check the status of the
operation via ``ironic node-show``. If it was successful,
``provision_state`` will be in the desired state. If it failed,
there will be information in the node's ``last_error``.
After creating a node and before moving it from its initial provision state of
``enroll``, basic power and port information needs to be configured on the node.
The Bare Metal service needs this information because it verifies that it is
capable of controlling the node when transitioning the node from ``enroll`` to
``manageable`` state.
To move a node from ``enroll`` to ``manageable`` provision state::
ironic --ironic-api-version 1.11 node-set-provision-state $NODE_UUID manage
ironic node-show $NODE_UUID
+------------------------+--------------------------------------------------------------------+

| provision_state | manageable | <- verify correct state
| uuid | 0eb013bb-1e4b-4f4c-94b5-2e7468242611 |
| ... | ... |
+------------------------+--------------------------------------------------------------------+
When a node is moved from the ``manageable`` to ``available`` provision
state, the node will be cleaned if configured to do so (see
:ref:`CleaningNetworkSetup`).
To move a node from ``manageable`` to ``available`` provision state::
ironic --ironic-api-version 1.11 node-set-provision-state $NODE_UUID provide
