Kubernetes集群部署方式

• 官方推荐的三种部署方式

• minikube

Minikube是一个工具，可以在本地快速运行一个单点的Kubernetes，仅用于尝试Kubernetes或日常开发的用户使用。

部署地址：https://kubernetes.io/docs/setup/minikube/

• kubeadm

Kubeadm工具，提供kubeadm init和kubeadm join，用于快速部署Kubernetes集群

部署地址：https://kubernetes.io/docs/reference/setup-tools/kubeadm/kubeadm/

• 二进制

推荐，从官方下载发行版的二进制包手动部署每个组件，组成Kubernets集群
