Node Operator: Kubernetes Node Management Made Simple 陈俊(Joe), Ant Financial Agenda • Background and Motivation • Introduction of Operators • Node-Operator • Advanced Topic: Teardown Cluster fast and convenient • Add & delete Node at any time • Upgrade Master & Node Components reliably • Canary Rollout • Master & Node Component Versions Management Motivation: Work Order Order Deployment Worker Order • Upgrade Nodes Versions • Upgrade Node 10.10.10.1 • Upgrade docker • Upgrade kubelet • Upgrade Node 10.10.10.2 • Upgrade docker • Upgrade kubelet …. Motivation: Work Order

解析相应的主机名（master 结点）到对应的ip地址，可以使用内网集群的dns服务器或写入/etc/hosts文件 里。如： 主机名 ip地址 k8s-master1.cof-lee.com 10.99.1.51 k8s-master2.cof-lee.com 10.99.1.52 k8s-master3.cof-lee.com 10.99.1.53 k8s-node01.cof-lee 10.99.1.61 k8s-node02.cof-lee.com 10.99.1.62 规划Pod网络： 10.244.0.0/16 规划Service网络： 10.7.0.0/16 # pod网络和service网络都要求为16位的地址块，且不能与环境中其他网络地址 段冲突 # hostnamectl set-hostname k8s-master1.cof-lee.com 99.1.51 k8s-master1.cof-lee.com k8s-master1 10.99.1.52 k8s-master2.cof-lee.com k8s-master2 10.99.1.53 k8s-master3.cof-lee.com k8s-master3 10.99.1.61 k8s-node01.cof-lee.com k8s-node01 10.99.1.62
