[TOC]Introduction to Kubernetes DispatchingIn addition to having the Kubernetes cluster scheduler automatically select a node for the pod resource (the default schedule is that the resources are sufficient and the load is as average as possible), there are situations where we want to have more control over how the pod should be dispatched. For example, some of the machines in the cluster are better configur

so on is called the "Replication Controller", where multiple pods of an application can share a single machine.Kubernetes supports a special network model, Kubernetes creates an address space and does not dynamically allocate ports, which allows the user to select any port they want to use, and for this function, it assigns an IP address to each pod. Kubernetes provides an abstraction of the
