Kubectl 是 Kubernetes 自带的命令行工具

https://storage.googleapis.com/kubernetes-release/release/stable.txt

2.下载（自行替换版本）
https://storage.googleapis.com/kubernetes-release/release/v1.18.4/bin/linux/amd64/kubectl

3.安装
赋可执行权限

1
chmod +x ./kubectl
移动到系统PATH中 
1
sudo mv ./kubectl /usr/local/bin/kubectl

1.下载minikube

1
curl -Lo minikube https://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v1.11.0/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

2.安装minikube
使用非virtualbox驱动模式
minikube start –driver=none

3.验证安装状态
minikube status

4.后续启动minikube
minikube start

Kubernetes Dashboard安装

1.下载部署文档

1
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml

2.检查docker images是否下载成功
docker images
如果镜像无法下载，k8s.gcr.io 替换为了 reg.qiniu.com/k8s 或者使用代理

3.修改DashBoard的Service端口暴露模式为NodePort

1
kubectl edit service kubernetes-dashboard -n kubernetes-dashboard
1
