本文采用redhat7.9作为测试环境虚拟机安装操作系统的步骤不再列出。
官方的docker镜像要求主机资源至少为2C10G。本机主机资源配置4c16G磁盘100G

国内从 DockerHub 拉取镜像有时会遇到困难此时可以配置镜像加速器。Docker 官方和国内很多云服务商都提供了国内加速器服务参考Docker Hub 镜像源 - 掘金 (juejin.cn)

docker镜像已经部署好了一个集群——obcluster这里不再部署。附上obd操作集群的常用命令
#启动集群
obd cluster start 集群名
#停止集群
obd cluster stop 集群名
#重启集群
obd cluster restart 集群名
#查看集群状况
obd cluster list
obd cluster display 集群名
#查看集群配置,也可以根据模板重新建一个配置文件重新部署新集群
