is responsible for "backstage". Each resource generally has a controller, and controller manager is responsible for managing those controllers. For example, we create a pod through Apiserver, and when the pod is created, Apiserver's task is done. And the next guarantee that pod status is always the same as we expected the responsibility of the Controller manager to ensure.　　　　Etcd. ETCD is a highly available key-value storage system that Kubernetes u

When a customer pod accesses another pod, the access request is forwarded by the native proxy.Borrowing a net diagram to express the relationship between functional components:Two. Basic Concept nodeNode is a working host in the Kubernetes cluster relative to master, and is also known as Minion in earlier versions. Node can be a physical host, or it can be a virtual machine (VM). The service

Kubernetes Controller Manager ServerController Manager Server is responsible for all other functions, such as the endpoints controller responsible for creating and updating endpoints objects.

is created, the Proxy obtains the configuration information of Services and Endpoints from etcd (or from file ), then, start a Proxy process on Minion Based on the configuration information and listen to the corresponding service port. When an external request occurs, the Proxy will distribute the request to the correct backend container for Processing Based on Load Balancer. Therefore, the Proxy not only solves the conflict between the same Service port on the same host machine, but also provi
