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.

How it works

The expected workflow is as follows:

1. 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.

2. The operator moves the node to manageable. It works because the agent power only requires to be able to connect
   to the agent.

3. 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.

4. A user deploys the node. Deployment happens normally via the
   already running agent.

5. In the end of the deployment, the node is rebooted via the reboot
   command instead of power off+on.

Enabling

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:

[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:

[pxe]
enable_netboot_fallback = true

If using discovery, 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.
