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

"Editor's note" Overlay network is one of the important solutions of Kubernetes network model, and flannel, as a mature solution for anxiety, can build overlay network based on a variety of backend, which is based on the Vxlan of Linux kernel Backend has obvious advantages in both performance and ease of use.

address. The container in the pod, called the app container, uses--net=container when it is created: to share the network space of the pod container.For example, the author has a kubernetes node host PT-169124, with an IP address of 192.168.169.124. The author's environment uses flannel as the bridge network drive of Docker, with ifconfig command can see flannel

As the Docker community continues to grow, CoreOS, Kubernetes, Hashicorp and other projects flourish. Flannel as an open-source networking component for containers, it also attracts engineers ' attention. The flannel is simple to use and can be configured with a Multi-host network connection only as a consistent store with ETCD belonging to the CoreOS family.Netw

Routing : The Linux system contains a complete routing feature that uses the routing table to determine where to send the IP layer when it processes the data to be sent or forwarded.

I. Introduction to the EnvironmentSecond, the environment constructionEnvironment construction here will not repeat, please refer to the previous article!http://blog.51cto.com/hostman/2103503Here we start by configuring flannel information into the databaseCreate a file Flannel-config.json, write the following:Cat >> Flannel-config.json {"Network": "10.10.0.0/16"

In the previous section we deployed ETCD, and this section installs and configures flannel. Build Flannel Flannel do not have a ready-made executable file available, you must build it yourself, the most reliable way is to build in the Docker container. But for build Docker mirror hosting in Gcr.io, domestic may not be directly accessible, for the convenience of e
