The watcher.api.controllers.v1.action Module

An Action is what enables Watcher to transform the current state of a Cluster after an Audit.

An Action is an atomic task which changes the current state of a target Managed resource of the OpenStack Cluster such as:

  • Live migration of an instance from one compute node to another compute node with Nova
  • Changing the power level of a compute node (ACPI level, …)
  • Changing the current state of a compute node (enable or disable) with Nova

In most cases, an Action triggers some concrete commands on an existing OpenStack module (Nova, Neutron, Cinder, Ironic, etc.).

An Action has a life-cycle and its current state may be one of the following:

Some default implementations are provided, but it is possible to develop new implementations which are dynamically loaded by Watcher at launch time.

class watcher.api.controllers.v1.action.Action(**kwargs)[source]

Bases: watcher.api.controllers.base.APIBase

API representation of a action.

This class enforces type checking and value constraints, and converts between the internal object model and the API representation of a action.

classmethod sample(expand=True)[source]
class watcher.api.controllers.v1.action.ActionCollection(**kwargs)[source]

Bases: watcher.api.controllers.v1.collection.Collection

API representation of a collection of actions.

classmethod sample()[source]
class watcher.api.controllers.v1.action.ActionPatchType(**kw)[source]

Bases: watcher.api.controllers.v1.types.JsonPatchType

static mandatory_attrs()[source]
class watcher.api.controllers.v1.action.ActionsController[source]

Bases: pecan.rest.RestController

REST controller for Actions.
