Editing an EgressNetworkPolicy object

As a cluster administrator, you can update the egress firewall for a project.

Prerequisites

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

  • Install the OpenShift CLI (oc).

  • You must log in to the cluster as a cluster administrator.

Procedure

  1. Find the name of the EgressNetworkPolicy object for the project. Replace <project> with the name of the project.

    1. $ oc get -n <project> egressnetworkpolicy

  2. Optional: If you did not save a copy of the EgressNetworkPolicy object when you created the egress network firewall, enter the following command to create a copy.

    1. $ oc get -n <project> egressnetworkpolicy <name> -o yaml > <filename>.yaml

    Replace <project> with the name of the project. Replace <name> with the name of the object. Replace <filename> with the name of the file to save the YAML to.

  3. After making changes to the policy rules, enter the following command to replace the EgressNetworkPolicy object. Replace <filename> with the name of the file containing the updated EgressNetworkPolicy object.

    1. $ oc replace -f <filename>.yaml
