State Machine Diagram
|
|
=====================
|
|
|
|
The diagram below shows the provisioning states that an Ironic node goes
|
|
through during the lifetime of a node. The diagram also depicts the events
|
|
that transition the node to different states.
|
|
|
|
Stable states are highlighted with a thicker border. All transitions from
|
|
stable states are initiated by API requests. There are a few other
|
|
API-initiated-transitions that are possible from non-stable states.
|
|
The events for these API-initiated transitions are indicated with '(via API)'.
|
|
Internally, the conductor initiates the other transitions (depicted in gray).
