Feature: Lifecycle
******************
.. contents::
:depth: 3
Summary
^^^^^^^
The "lifecycle" feature enables a PDP-D to work with the Dublin Release Policy architectural framework.
The lifecycle feature maintains three states: TERMINATED, PASSIVE, and ACTIVE.
The PAP (Dublin style) interacts with the lifecycle feature to put a PDP-D in PASSIVE or ACTIVE states.
The PASSIVE state allows for Tosca Operational policies to be deployed.
Policy execution is enabled when the PDP-D transitions to the ACTIVE state.
This feature can coexist side by side with the legacy mode of operation that predates the Dublin release.
Usage
^^^^^
The feature is enabled by default.
The lifecycle "enabled" property can be toggled with the "features" command line tool available in PDP-D containers.
.. code-block:: bash
