The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end. Between the service and the back-end pod replica cluster, the docking is done through the label selector. The function of RC is to ensure service ability and service quality

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

How to build a Kubernetes (k8s) Environment The official version of k8s is updated too quickly. Many articles on the Internet are outdated and many tools and interfaces have changed. the official website does not have a good understanding. Here we only record the process of setting up the k8s environment and will not talk about many k8s concepts. Therefore, we recommend that you first understand various concepts and then build the environment, then, i

Helm IntroductionDeploying container cloud Applications (container or microservices orchestration) in Kubernetes is a challenging task, Helm is to simplify the installation of a client tool for deploying container cloud applications in Kubernetes. Helm enables developers to define, install, and upgrade container cloud applications in Kubernetes. At the same time,

Ubernetes is the King of container orchestration and scheduling, it beats the competitors Docker swarm and Apache Mesos, opens the bright future, microservices can be self-repairing, can be automatically expanded, can cross zone, Region even across cloud providers for federate. In this new era of cloud-native applications, it is becoming increasingly important to have a simple insight into how services interact with each other, which can be different from a haystack-wide search for a specific ca

master node's own IP address, cluster_ip_subnet for the entire cluster subnet range, For example, 192.168.0.0/16, while Master_switch_subnet is the subnet range that the pod on the master node can allocate, such as 192.168.1.0/24SOURCE Link: https://github.com/YaoZengzeng/scripts/blob/master/ovn-k8s-master.sh4, at first I was using KUBEADM to build k8s cluster, but when the API server through http://127.0.0.1:8080 to find that the port is not open, it may be kubeadm by default is not open the p

The essence of swarm and k8s are container orchestration services.They can abstract the underlying host, and then start the application from a built-in image and eventually deploy it to a host on a docker basis. Which scenario should be chosen as our container cloud service? I think k8s (kubernetes short) and swarm compared to MySQL and SQL Server comparison, the former lightweight, implementation fast, in order to achieve core functions, more suitabl
