there exist two kinds of servers, aMasterand aWorker node. These servers can be Virtual Machine(VM) or physical servers(Bare metal). Together, these servers form a Kubernetes cluster and are controlled by the services that make up the Control Plane. ...
这时vm3上,由redis cluster自动恢复vm3slave2(6380) —> master2(6380) 提升为master,集群工作正常,业务不中断。 恢复关掉的的机器 当我们重新启动vm2, 这时候集群的状态: 这时集群工作正常,此时vm3有2个master。如果我们关掉vm3,会让集群中2个master同时下线,导致集群无法自动恢复。 重点:执行以下脚本,提升s...

本章我们将部署三个节点的Kubernetes Cluster,如图3-1所示: k8s-master是Master, k8s-node1 和 k8s-node2 是 Node。 所有节点的操作系统均为Ubuntu 16.04, 当然其他Linux也是可以的。 官方安装文档可以参考 https://kubernetes.io/docs/setup/independent/install-kubeadm/。
