 Installing Policies

-The OOM default installation will come with no policies pre-configured.  There is a sample script used by integration teams to load policies to support all 4 use cases at:   /tmp/policy-install/config/push-policies.sh in the pap container within the pap pod.   This script can be modified for your own particular installation, for example if only interested in vCPE use cases, remove those vCPE related API REST calls.   For the vFW use case, you may want to edit the encoded operational policy to point to the proper resourceID in your installation.

-A PDP-D container failure can be simulated by performing a"policy stop" operation within the PDP-D container, this in fact will shutdown the PDP-D service.    The kubernetes liveness operation will detect that the ports are down, inferring there's a problem with the service, and in turn, will restart the container.   In the following example will cause PDP-D 3 to fail.

 PDP-X Scaling
 ^^^^^^^^^^^^^
 
-To scale a new PDP-X, set the replica count appropriately.   In our scenario below, we are going to scale the PDP-X with a new replica, PDP-X 2, to have a pool of 3 PDP-X.
+To scale a new PDP-X, set the replica count appropriately.   
+
+In our tests below, we are going to work with the OOM policy component in isolation.   In this exercise, we scale the PDP-X with 1 additional replica, PDP-X 1.

 PDP-D Scaling
 ^^^^^^^^^^^^^
 
-To scale a new PDP-D, set the replica count appropriately.   In our scenario below, we are going to scale the PDP-D service with a new replica, PDP-D 4, to have a pool of 5 PDP-D.
+To scale a new PDP-D, set the replica count appropriately.   In our scenario below, we are going to scale the PDP-D service to add a new pod (2 active PDP-Ds).
