yogananth-subramanian	8806781a4f	Pod network outage Chaos scenario ... 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' ````	2023-05-15 10:43:58 -04:00
