如何在kubernetes中配置Master02
这篇文章为大家分享有关在kubernetes中配置Master02的方法。文章涵盖Master02的配置和使用方法，希望大家通过这篇文章能有所收获。服务器角色分配角色地址安装组件master192.168.142.220kube-apiserver kube-controller-manager kube-scheduler etcdmaster02192.168.142.120kube-apiserver kube-controller-manager kube-schedulernode1192.168.142.136kubelet kube-proxy docker flannel etcdnode2192.168.142.132kubelet kube-proxy docker flannel etcdnginx1192.168.142.130nginx keepalivednginx2192.168.142.140nginx keepalived一、Master02配置分隔符前的操作均在master01上进行
复制目录到master02复制kubernetes目录到master02
# scp -r /opt/kubernetes/ root@192.168.142.120:/opt复制etcd目录到master02
master02一定要有etcd证书，否则apiserver服务无法启动
# scp -r /opt/etcd/ root@192.168.142.120:/opt复制服务启动脚本kube-apiserver.service kube-controller-manager.service kube-scheduler.service
# scp /usr/lib/systemd/system/{kube-apiserver,kube-controller-manager,kube-scheduler}.service root@192.168.142.120:/usr/lib/systemd/system/修改服务脚本实际上仅需要修改apiserver即可
