The scenario introduces network latency, packet loss, and bandwidth restriction in the Pod's network interface. The purpose of this scenario is to observe faults caused by random variations in the network.
Below example config applies ingress traffic shaping to openshift console.
````
- id: pod_ingress_shaping
config:
namespace: openshift-console # Required - Namespace of the pod to which filter need to be applied.
label_selector: 'component=ui' # Applies traffic shaping to access openshift console.
network_params:
latency: 500ms # Add 500ms latency to ingress traffic from the pod.

Pod network outage chaos scenario blocks traffic at pod level irrespective of the network policy used.
With the current network policies, it is not possible to explicitly block ports which are enabled
by allowed network policy rule. This chaos scenario addresses this issue by using OVS flow rules
to block ports related to the pod. It supports OpenShiftSDN and OVNKubernetes based networks.
Below example config blocks access to openshift console.
````
- id: pod_network_outage
config:
namespace: openshift-console
direction:
- ingress
ingress_ports:
- 8443
label_selector: 'component=ui'
