Play with the Sample API Server
Uncover some of the deployment details associated with aggregated apiservers.
We'll cover the following...
Overview
Aggregated API servers are usually built with the generic API server library k8s.io/apiserver. They run as stand-alone processes serving API groups with multiple versions. They could run inside or outside of the cluster. In the former case, they run as Pods, with a service in the front. By declaring an APIService object, we can hook our aggregated apiservers up to the kube-apiserver, which can make them work coherently. In the APIService object, we can correlate a service to indicate the accessible endpoint of our aggregated apiservers. If they are running in the cluster, the service could be a normal ClusterIP service. If running outside of a Kubernetes cluster, the service could also be an ExternalName service.
In this lesson, we’re going to deploy a sample aggregate apiserver and take a closer look at what ...
