Installation Steps PreparationsDisable Firewall To avoid conflicts with Docker's iptables, We need to disable the firewall on the node: 12 $ systemctl stop firewalld$ systemctl disable firewalldInstall NTP To keep the time of each server consistent, you also need to install NTP for all servers: 123 $ yum -y install ntp$ systemctl start ntpd$ systemctl enable ntpdDeploy

Introduction and practice of pod in kubernetes The concept of podDetailed pod explanation can refer to k8s official website, the concept of pod mainly has the following points:(1) Pod is the smallest and simplest unit that you can create and deploy in Kubernetes. A pod represents a process that runs in a cluster;(2) How to use pod in kubrenetes cluster;(3) How to manage multiple containers in pod Unde

The Traefik principle can be consulted in the official documentation: https://docs.traefik.io/, This document can also be consulted about the service exposure of kubernetes and the rationale for using Traefik as a k
