In this chapter we will integrate the Input with the Load Balancer (henceforth LB). The first, as we have just seen in the previous chapter, was presented as an entity that lives within the Kubernetes cluster and comes in the form of a Pod. The second, presented a few pages ago, is an entity that lives outside the cluster and is hosted by the Cloud Provider in use (OpenStack in our case). We strongly recommend a review of these two objects before proceeding with the reading, consulting the pages linked above or through other sources.
We will then explain how to create a connection point between these two components. The joining point consists of a file, containing the access credentials (username, password) and the coordinates (projectID, region) of the OpenStack tenant that we want to link. The purpose, in fact, is to automatically create the LB and its components (Listener, Pool, Policy, etc.), starting from the Kubernetes cluster. Finally, we point out that this page is based on a GitHub guide, which you can reach from here.
