Advertise Apps on Site Service Network

Objective

This guide provides instructions on how to advertise your apps on the vK8s site service network. To know more about vK8s, see Volterra vK8s.

A vK8s site service network is a Volterra internal network that is used for communication between apps running on the Volterra sites and not intended for advertising on the public network. Using the site service network, you can advertise apps on the Volterra CE sites or RE sites.

Using the instructions provided in this guide, you will be able to update a 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:

Note: If you do not have an account, see Create a VES Account.

  • One or more Volterra sites in case you want to advertise on the CE sites.

Note: If you do not have a site, see Site Management documentation for instructions on deploying a site.

  • Apps deployed on Volterra vK8s

Note: If you do not have apps deployed on vK8s, see Create vK8s Object and vK8s Deployment.
