minikube 安装

minikube为开发或者测试在本地启动一个节点的kubernetes集群，minikube打包了和配置一个linux虚拟机、docker与kubernetes组件。给开发者提供充分的环境，minikube支持一下kubernete的特性：

• DNS
• NodePorts
• ConfigMaps 与 Secrets
• Dashboards

不支持如下特性:

• LoadBalancers
• PersistentVolumes
• Ingress

先决条件

主板BIOS开启VT-x/AMD-v,检查方法如下：

• linux: cat /proc/cpuinfo | grep 'vmx|svm'
• macos: sysctl -a | grep machdep.cpu.features | grep VMX 

• 安装Virtualbox

启动集群

$ minikube start
Starting local Kubernetes cluster...
Kubernetes is available at https://192.168.99.100:8443.
Kubectl is now configured to use the cluster.

$ kubectl config use-context minikube

$ kubectl get pods --all-namespaces
