Among them, the master node runs a group of processes related to cluster management Etcd, API Server, Controller Manager, Scheduler, and the last three components constitute the Kubernetes Master control Center, which realizes the wh

the service registry through the built-in lb component, caches and periodically refreshes the target service address list. Then select a target service address with a load balancing policy, and finally initiate a request to the target service. LB and service discovery capabilities are dispersed within the process of each service consumer, while the service consumer and the service provider are directly called, with no additional overhead and better performance. The main issues of the programme:

This is a creation in Article, where the information may have evolved or changed. This series of articles is mainly for TIKV community developers, focusing on tikv system architecture, source structure, process analysis. The goal is to enable developers to read, to have a preliminary understanding of the TIKV project, and better participate in the development of TIKV. TIKV is a distributed KV system that uses the Raft protocol to ensure strong data consistency, while supporting distributed trans

in the same number of pods as defined RC also has a magical mechanism: rolling updates; For example, now that a service has 5 running pods, the pod itself is now in the business of being updated and can be replaced by a mechanism to implement the entire RC update 3:service Services-as-a-service, an interface that truly provides services, and the ability to force pod-provided services into the extranet, with one or more pods per service backend

overlay network to achieve container communicationDocker1.12 still inherits the overlay network model, and provides a strong network guarantee for its service registration discovery.Docke's registration Discovery principle is actually using a distributed key-value storage as the abstraction layer of storage. Docker 1.12 provides built-in Discovery services so that the cluster does not need to rely on external Discovery services such as consul or ETCD

This is a creation in Article, where the information may have evolved or changed. Hello everyone, I am Xu Chao, engaged in Kubernetes development has been more than two years. Today, I talk about Client-go repository from a developer's point of view and how to build a Controller with Client-go. At the same time, we also give you a talk about the development process encountered in the pit, I hope everyone in the development of the time can be around the pit. In addition, I will also talk abou

The implementation principle and configuration of k8s Ingress are described in the previous article, and the alternative Traefik is described in this paper. Before we start the configuration, let's review the implementation of the Ingress release k8s service, which requires the following components to be used ingress scenarios:1. Reverse Proxy Load Balancer2. Ingress control3, IngressWhere Ingress control is responsible for communicating with apiserver, monitoring pod and service changes, and up
