k8s操作手册 前言： 1.蓝色字体表示命令行命令，正式执行时不要复制前面的#号，#号只是提示应 该使用root权限操作 2.绿色字体表示注释，有时注释太多就不用绿色表示了 3.注意：本文档的所有操作请先在测环境进行实践，请不要直接在真实的服务 器中操作！ 版权声明： 本文档以开源的形式发布，所有条款如下： （1）无担保：作者不保证文档内容的准确无误，亦不承担由于使用此文档所导致的任何后果 更新日期：2023-12-29 ★第0章、K8S集群搭建准备工作 相关单词原义： docker 码头工人 pod 集装箱 kubernetes 舵手，领航员 helm 舵轮，驾驶盘 chart 图表，海图 ①k8s对系统要求 linux内核在3.10及以上 ②规划主机名及ip k8s的服务器使用固定ip地址，配置主机名，要求能解析相应的主机名（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

★遍历字典dic�onary ①遍历key dictx = {"k1": "v1", "k2": "v2", "k3": "v3"} for key in dictx.keys(): print(key, "-------->", dictx[key]) ②遍历value dictx = {"k1": "v1", "k2": "v2", "k3": "v3"} for value in dictx dictx.values(): print(value) ③遍历item dictx = {"k1": "v1", "k2": "v2", "k3": "v3"} for k, v in dictx.items(): print(k, "---->", v) ★list/set/dic�onary增删改查操作 ①list数据操作（有序，数值可重复） listxx.append(x) #添加多个键值对，lx为另一 dictionary value2 = dictxx["k2"] # 取指定key对应的值 k,v=dictxx.popitem() # 随机返回并删除一个键值对 del dictxx["k2"] # 删除指定key的这对键值对 ★string和bytes转换
