Let's say something like this is in your pod logs.
"Post "https://www.example.com/api": context deadline exceeded (Client.Timeout exceeded while awaiting headers)"
This typically means the pod is unable to submit the request to the target URL (https://www.example.com/api in this example). Egress provides a way for an application deployed on OpenShift to access an external URL, such as http://www.example.com.
The oc get networkpolicies command can then be used to list the network policies that have been created in the project. If there is a network policy in the project, check to see if the network policy is denying egress traffic.
~]$ oc get networkpolicies
NAME POD-SELECTOR AGE
allow-ingress-region-east region=east 41s
The oc get egressnetworkpolicies command can then be used to list the egress network policies that have been created in the project. If there is an egress network policy in the project, check to see if the egress network policy is denying egress traffic.
~]$ oc get egressnetworkpolicy
NAME AGE
