Editing an egress firewall for a project

As a cluster administrator, you can modify network traffic rules for an existing egress firewall.

Viewing an EgressNetworkPolicy object

You can view an EgressNetworkPolicy object in your cluster.

Prerequisites

  • A cluster using the OpenShift SDN default Container Network Interface (CNI) network provider plugin.

  • Install the OpenShift Command-line Interface (CLI), commonly known as oc.

  • You must log in to the cluster.

Procedure

  1. Optional: To view the names of the EgressNetworkPolicy objects defined in your cluster, enter the following command:

    $ oc get egressnetworkpolicy --all-namespaces

  2. To inspect a policy, enter the following command. Replace <policy_name> with the name of the policy to inspect.

    $ oc describe egressnetworkpolicy <policy_name>
