The node nodes of Kubernetes are composed of Kubelet, Kube-proxy, flannel, dockerd four components, this paper mainly analyzes the functions and principles of kube-proxy components. Pod is the smallest unit of resource allocation in kubernetes and the smallest entity to perform tasks.
Each pod has a separate IP on the flannel overlay network. Pod Communication in node nodes is impleme
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 with physical machines, but also between containers across the network. Kubernetes's ip-per-pod design idea has many benefits, such as: Fr
Kubernetes 1.9 clusters use traefik to publish services
This section describes how to use traefik to publish services in the kubernetes 1.5.2 cluster environment. Traefik is deployed in the daemonset mode. The http protocol is used to connect to the api-server, and rbac is not configured. This article describes how to deploy traefik in k8s 1.9 using deployment for service release.

Apiserver is the primary management node for the entire cluster, where the user configures and organizes the cluster through Apiserver, while the interactions between the nodes in the cluster and the ETCD store interact with the Apiserver. Apiserver implements a set of Restfull interfaces that allow users to interact directly wit

Kubernetes using NFS as a shared storageKubernetes managed containers are encapsulated, and sometimes we need to put logs from the container running locally or shared storage to prevent the container from going down, and the logs can also analyze the problem. Kubernetes's shared storage scheme is currently more prevalent in three, namely: Nfs,glusterfs and Ceph.Previously wrote an article kubernetes use Glu

Kubernetes currently provides two ways to create the required pod,service,replicationcontroller, one is through Kubectl create-f, a restful interface via HTTP, because of the work item's reason, Need to be customized according to the actual business needs of the development of K8s API, I used the library is the official, code base address: Https://github.com/

kubernetes Introduction
Kubernetes is a container cluster management system that Google Open-source in June 2014, using the Go language development, Kubernetes also called k8s.
K8s is a Borg container cluster management system inside Google, Borg has been operating on Google's mass production for 10 years.
K8s is mainly used for automated deployment, expansion
1.1. What is Kubernetes?A new approach to distributed architecture based on container technologyA complete distributed system support platformKubernetes is an open source project launched by the Google team, which aims to manage containers across multiple hosts, provide basic deployment, maintenance, and use scaling, primarily to implement the language as the Go language.1.2. Basic ConceptsNode: In Kubernetes
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 are required to be accessed directly from each other's IP. The reason for this principle is that the user does not need to consider ho

Heapster is a container cluster monitoring and performance analysis tool that naturally supports kubernetes and CoreOS.Kubernetes has a well-known surveillance agent-cadvisor. The cadvisor is run on each kubernetes node, and it collects monitoring data (cpu,memory,filesystem,network,uptime) for both native and container.In the newer version, K8S has integrated the Cadvisor functionality into the Kubelet com
