minikube

服务器启动

# 启动集群
minikube start
# 启动集群并使用docker驱动
minikube start --driver=docker
To make docker the default driver:minikube config set driver docker
# 查看节点。kubectl 是一个用来跟 K8S 集群进行交互的命令行工具
kubectl get node
# 停止集群
minikube stop
# 清空集群
minikube delete --all
# 安装集群可视化 Web UI 控制台
minikube dashboard

minikube 安装以后可以再安装kubectl ，不必使用minikube kubectl 来用

kubectl cluster-info 查看集群配置是否正确

kubectl容器操作

kubectl get namespace//获得所有命名空间
kubectl get pod --all-namespaces -o wide//获得命名空间下的所有容器通过kubectl get pods查询，然后通过下面命令进入
kubectl exec -it nas-all-0 /bin/bash新版使用这个进入容器
kubectl exec test-pod -it -- /bin/bash//进入命名空间下的容器，application是命名空间，psqls-0是容器
kubectl exec -it -n application psqls-0 /bin/bash//拷贝内容内文件，拷贝出来
kubectl cp -n application psqls-0:/var/lib/postgresql/data/pg_wal /home
//拷贝进去
kubectl cp /home/dades/pg_wal -n application psqls-0:/var/lib/postgresql/data/pg_wal

kubect pod 操作

kubectl get pod -o wide
kubectl get pod -o wide -n <namespace-name># 查看pod详细信息
kubectl describe pod <pod-name>Name:             testapp

pod 其他操作

# 查看日志
kubectl logs <pod-name># 进入容器
kubectl exec -it <pod-name> -- /bin/bash

dashboard

minikube dashboard &

返回的url http://127.0.0.1:42005/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/ 为访问地址

但此地址只是容器代理出来的地址，只能本机内网访问，要想在外网访问 dashboard 的UI 界面，需要使用kubectl做一层代理。
