centos 配置连接集群 kubectl 客户端执行k8s脚本

在这里插入图片描述

kubectl 执行结果，一键生成StatefulSet+pod+Service+config

在这里插入图片描述

  1. Deployment pod重启ip和名称随机分配，适合java服务类部署
  2. StatefulSet pod重启ip和名称固定分配，适合mysql数据库类部署
  3. DaemonSet 节点机器始终只有一个pod在后台运行，日志采集器
  4. Job 批处理应用服务任务，一次性完成处理结束
  5. CronJob 定时应用服务任务，按corn表达式循环处理

  1. k8s 部署nacos总配置文件 k8s-deploy-nacos-total.yaml
