Kubernetes学习指南：保姆级实操手册03——规划部署
一、部署节点规划
Hostname | ip | roles |
k8s-master01 | 10.255.210.1 | master |
k8s-master02 | 10.255.210.2 | master |
k8s-master03 | 10.255.210.3 | master |
k8s-node01 | 10.255.210.4 | worker node |
k8s-node02 | 10.255.210.5 | worker node |
k8s-node03 | 10.255.210.6 | worker node |
apiserver.fq.com | 10.255.210.99 | 负载均衡VIP |
serviceSubnet | 10.96.0.0/12 | service网段 |
podSubnet | 10.100.0.0/16 | pod网段 |
管理节点(master)运行服务：etcd、kube-apiserver、kube-scheduler、kube-controller-manager、docker、kubelet、keepalived、haproxy 工作节点（worker node）运行服务：docker、kubelet、kube-proxy 扩展阅读：[[k8s master节点和worker 主要运行的软件]]
