The Kubernetes network model is made up of four parts from inside to outside:
The network where the pod interior container resides
The network where the pod resides
Network for communication between pod and service

Because scenarios where private clouds are deployed in the enterprise are more prevalent, it is necessary to build a network environment that meets kubernetes requirements before running kubernetes + Docker clusters in a private cloud. In today's open source world, there are many open source components that can help us get through the

But the network performance and delay is poor based on overlay mode, and the network architecture is more complex. And banks need to be simple

Kubernetes Network Model
A fundamental principle of the Kubernetes network model design is that each pod has a separate IP address, and that all pods are in a flat network space that can be directly connected. So whether or not they run in the same node (host), they
Article from: Listen to the Cloud blogAs our business continues to grow, our number of applications has exploded. With the growth of application explosion, the difficulty of management is increased. How to quickly complete the expansion while the business explosion is growing is a big challenge. The advent of Docker happened to solve our problem. With Docker, we can quickly complete the expansion and contraction, and the configuration is uniform and error-prone.In the Docker cluster management s
1. PrefaceKubernetes designed a special network model that deviates from the native Docker network model. In this design, Kubernetes defines an abstract concept: pods, each pod is a collection of containers, and there is a shared IP, and all containers share the same network namespace. Pods can communicate not only wit
Direct start:5.1, Flannel IntroductionFlannel is an overlay networking (overlay network) tool designed by the CoreOS team for Kubernetes to help each kuberentes host with CoreOS have a complete subnet. Kubernetes assigns a separate IP address to each pod, which makes it easier for Containers in the same pod to connect to each other, and flannel to set a subnet fo
The previous blog has introduced the deployment of a simple kubernetes cluster, but the cluster environment does not have a reasonable network configuration. In the actual production to realize the communication of the components in the cluster, it is necessary to use the network plug-in provided by the third party.Flannel binary Installation1.
