=================================
Deploying without BMC Credentials
=================================
The Bare Metal service usually requires BMC credentials for all provisioning
operations. Starting with the Victoria release series there is limited support
for inspection, cleaning and deployments without the credentials.
.. warning::
This feature is experimental and only works in a limited scenario. When
using it, you have to be prepared to provide BMC credentials in case of
a failure or any non-supported actions.
How it works
============
The expected workflow is as follows:
#. The node is discovered by manually powering it on and gets the
`manual-management` hardware type and `agent` power interface.
If discovery is not used, a node can be enrolled through the API and then
powered on manually.
#. The operator moves the node to `manageable`. It works because the `agent`
power only requires to be able to connect to the agent.
#. The operator moves the node to `available`. Cleaning happens normally via
the already running agent. If reboot is needed, it is done by telling the
agent to reboot the node in-band.
#. A user deploys the node. Deployment happens normally via the already
running agent.
#. In the end of the deployment, the node is rebooted via the reboot command
instead of power off+on.
Enabling
========
:doc:`fast-track` is a requirement for this feature to work. After enabling it,
adds the ``agent`` power interface and the ``manual-management`` hardware type
to the enabled list:
.. code-block:: ini
[DEFAULT]
enabled_hardware_types = manual-management
enabled_management_interfaces = noop
enabled_power_interfaces = agent
[deploy]
fast_track = true
As usual with the ``noop`` management, enable the networking boot fallback:
.. code-block:: ini
[pxe]
enable_netboot_fallback = true
If using discovery, :ironic-inspector-doc:`configure discovery in
ironic-inspector <user/usage.html#discovery>` with the default driver set
to ``manual-management``.
Limitations
===========
* Only the ``noop`` network interface is supported.
* Undeploy and rescue are not supported, you need to add BMC credentials first.
* If any errors happens in the process, recovery will likely require BMC
credentials.
* Only rebooting is possible through the API, power on/off commands will fail.
