还没有在本地运行k8s集群

二. 安装minikube

2.1 brew install安装minikube

brew install minikube

2.2 minikube开启k8s

minikube start

2.3 kubectl命令查看相关信息

kubectl cluster-info

查看pods

kubectl get po -A
NAMESPACE     NAME                               READY   STATUS    RESTARTS      AGE

kube-system   storage-provisioner                1/1     Running   1 (13m ago)   13m

查看node信息

kubectl get nodes
NAME       STATUS   ROLES           AGE   VERSION
minikube   Ready    control-plane   16m   v1.26.3

2.4 开启dashboard

minikube dashboard

http://127.0.0.1:62643/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/#/workloads?namespace=default

三. minikube常用命令

Pause Kubernetes without impacting deployed applications:

minikube pause

Unpause a paused instance:

minikube unpause

Halt the cluster:

minikube stop

Change the default memory limit (requires a restart):

minikube config set memory 9001

Browse the catalog of easily installed Kubernetes services:

minikube addons list

Create a second cluster running an older Kubernetes release:

minikube start -p aged --kubernetes-version=v1.16.1

Delete all of the minikube clusters:

minikube delete --all
