Author: Peng Jingtian 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

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

This is a creation in Article, where the information may have evolved or changed. Kris Nova, of Microsoft, shares lessons on over-engineering from she experience contributing to Kubernetes Kops. In hers spare time, she runs a Kubernetes special Interest Group bringing Kubernetes to AWS, all and working on Microsoft Acs. She ' s writing a book called Cloud Native

The role of Kubernetes Scheduler is to bind controller manager to a new pod according to a specific scheduling algorithm and scheduling policy to a suitable node in the cluster, and to write the binding information to the ETCD.I.

Brief Description:Using the Rke tool, on the 192.168.3.161 machine, create a kubernetes cluster with two nodes (192.168.3.162 and 192.168.3.163). Rke automatically creates KUBE_CONFIG_CLUSTER.YML configuration files in the/home/user directory.On another server (192.168.3.160), run the Rancher Server 2.0 container. After running, use the https://192.168.3.160 address to access Rancher Server 2.0 preview. (Note: No longer the previous 8080 port)In the R

To provide a richer user experience, Kubernetes also developed a WEB-based Dashboard that enables users to deploy containerized applications with Kubernetes Dashboard, monitor the status of applications, perform troubleshooting tasks, and manage

This article describes the use of Node-exporter, Prometheus, Grafana to monitor the cluster in a k8s cluster.Its implementation principle is somewhat similar to elk, EFK combination. The Node-exporter component collects the metrics monitoring data on the node and pushes the data to Prometheus, Prometheus is responsible for storing the data, and grafana the data to the user in a graphical form on the Web page. Before you begin, it is necessary to understand what the next Prometheus is. Prometheu

In a cluster with TLS enabled, each time the cluster interacts with identity authentication, using Kubeconfig (i.e., certificates) and token two authentication methods is the simplest and most common authentication method.Take Kubectl as an example to introduce the configuration of Kubeconfig. Kubectl is just a go-written executable program that can be used by any node in the cluster as long as the appropriate Kubeconfig is configured for Kubectl. Kubectl Default is to find files with file names

Deploying Heketi and Glusterfs in Kubernetes[TOC]1. PrefaceIn Kubernetes, using the Glusterfs file system, the procedure is usually:Create brick--> Create volume--> Create pv--> create pvc-->pod mount PVCIf you are creating more than one PV, you need to manually repeat these interlocking steps, Heketi can resolve these duplication problems.Heketi is used to manage the life cycle of the glusterfs volume and

By default, Kubernetes has a certificate validity period of 1 years when initializing a cluster. Manually generating certificates can avoid this problem.
