Editing an egress firewall for a project

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

Editing an egressFirewall object

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

Prerequisites

  • A cluster using the OVN-Kubernetes network plugin.

  • Install the OpenShift CLI (oc).

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

Procedure

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

    $ oc get -n <project> egressfirewall

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

    $ oc get -n <project> egressfirewall <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 egressFirewall object. Replace <filename> with the name of the file containing the updated egressFirewall object.

    $ oc replace -f <filename>.yaml
