This article will be based on the previous article on the configuration of the DNS service in the Kubernetes cluster environment, in the k8s cluster, pod life cycle is short, pod restart IP address will change, for the application this is unacceptable, in order to solve this problem, The k8s cluster cleverly introduces the DNS service to realize the discovery of the service, in which DNS requires a total of 4 components in the k8s cluster, each of whi

, such as local, you can use the same kube-config as Kubectl to configure the clients. If you're on the cloud, like Gke, you'll need an import Auth Plugin. The Clientset is generated with Client-gen. If you open pkg/api/v1/tyeps.go, there is a line of comments on the pod definition, called "+genclient=true", which means that you need to generate a client for this type, and if you want to do your own API type extension, The corresponding clients can also be generated in this way. Clientset
