Advertise Apps on Site Service Network

Published April 5, 2023 | Last modified March 20, 2025

Objective

This guide provides instructions on how to advertise your apps on the vK8s site service network in F5® Distributed Cloud Services. To know more about vK8s, see vK8s.

A vK8s site service network is an F5 internal network that is used for communication between apps running on the F5 Distributed Cloud Services sites and not intended for advertising on a public network. Using the site service network, you can advertise apps on the Customer Edge (CE) sites or Regional Edge (RE) sites.

Using the instructions provided in this guide, you can update an HTTP or TCP load balancer advertising the services on the vK8s site service network of a given set of sites or virtual sites.

Prerequisites

The following prerequisites apply:

  • A valid account is required. If you do not have an account, see Create an Account.

  • One or more sites in case you want to advertise on the CE sites. If you do not have a site, see Site Management documentation for instructions on deploying a site.

  • Apps deployed on F5 vK8s. If you do not have apps deployed on vK8s, see Create vK8s Object and vK8s Deployment.

Set Custom Advertisement for Load Balancer

The instructions in this guide cover advertising on the site service network for an HTTP load balancer. However, the same instructions also apply for a TCP load balancer.

Advertise policies can be viewed and managed in multiple services: Shared Configuration and Multi-Cloud App Connect.

This example shows Advertise Policies configuration in Multi-Cloud App Connect.

  • From the F5® Distributed Cloud Console (Console) homepage, select Multi-Cloud App Connect.
