k8s Basic Concepts1. NodeNode as a working node in the cluster, running a real application, the smallest running unit kubernetes managed on node is the pod. Node runs Kubernetes's kubelet, Kube-proxy service processes, which are responsible for pod creation, startup, monitoring, restart, destruction, and load balancing for software patterns. The information that node contains: node address: The IP address of the host, or node ID. node op

PrerequisitesKubernetes Cluster 1, start Redis Master use replication controller to ensure that only one pod is running (when a node is down,

First, prefaceKubernetes is the Google Open Source container cluster management system, based on Docker to build a container scheduling service, providing resource scheduling, balanced disaster recovery, service registration, dynamic expansion capacity and other functional suites, currently the latest version is 0.6.2.

How to obtain a Kubernetes image in China I. background As we all know, due to domestic network reasons, when building a Kubernetes environment, we often encounter situations where necessary images cannot be found. After all, it is not a good way to pick up junk in DockerHub. This article will teach you how to build your own image repository in DockerHub. Requirement: You have a GitHub account and a DockerH

Introduction to deploying Calico Network Calico Components: The Felix:calico agent runs on each node, setting network information for the container: IP, routing Rules, iptable rules, etc. Etcd:calico Back-End storage BIRD:BGP Client: Responsible for broadcasting Felix's routing information set on each node to the Calico network (via the BGP Protocol). BGP Route Reflector: Hierarchical routing distribution for large-scale clusters. Calico:calico command-line administratio

With the popularity of micro-service architectures and the trend of cloud-native, containerized microservices have become the best product of continuous delivery and have become the kubernetes best ecosystem for operation and maintenance containers. Practice out of knowledge, since kubernetes the study, wrote a series of articles, in order to be able to learn from each other, to find knowledge of the loopho

As early as half a year ago, the company began to implement the container deployment scheme Appos, although the publishing interface is too geek, very obscure, but carefully studied really feel very powerful, after the implementation of the container, computing resources (CPU, memory) utilization can be greatly improved, reduce the number of servers, thereby saving technical costs. Coincidentally, a number of friends in the start-up companies are also recently trying to do micro-services, contai

Tags: composition instance provider application Application class version style implementationThe lifespan of kubernetes pods is limited and they are not resurrected, so although each pod has its own IP address, these IP addresses are unreliable and disappear as the pod dies. This poses a problem, if some of the pod's collections (called backends) are other pods of the cluster (called frontends), how do these frontends find and always know which backe

In the first two parts of this series we describe the overall process of API server and how the API objects are stored in ETCD. In this article we will explore how to extend the API resources.In the beginning, the only way to extend the API resources is to extend the relevant API source code and integrate it into the resources you need. Or, push a whole new type into the community code for the new core object API. However, this can lead to a constant increase in the core API resource types until
