交互
如果已经安装了kubectl,就可以直接使用kubectl访问集群了
$ kubectl get po -A NAMESPACE NAME READY STATUS RESTARTS AGE kube-system coredns-558bd4d5db-jjh5r 1/1 Running 1 108d kube-system etcd-minikube 1/1 Running 1 108d kube-system kube-apiserver-minikube 1/1 Running 2 108d kube-system kube-controller-manager-minikube 1/1 Running 1 108d kube-system kube-proxy-fc8h2 1/1 Running 1 108d kube-system kube-scheduler-minikube 1/1 Running 1 108d kube-system storage-provisioner 1/1 Running 3 108d kubernetes-dashboard dashboard-metrics-scraper-5594458c94-mvbm8 1/1 Running 0 4m43s kubernetes-dashboard kubernetes-dashboard-654cf69797-8mgfh 1/1 Running 0 4m43s
如果没有安装，则minikube可以帮你下载合适版本的kubectl
$ minikube kubectl -- get po -A
账号minikube之后，一些服务比如存储，并没有启动。我们需要打开
$ minikube dashboard 🔌 Enabling dashboard ... ▪ Using image kubernetesui/dashboard:v2.3.1 ▪ Using image kubernetesui/metrics-scraper:v1.0.7 🤔 Verifying dashboard health ... 🚀 Launching proxy ... 🤔 Verifying proxy health ... 🎉 Opening http://127.0.0.1:63775/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/ in your default browser...此时可以通过web炉具蓝旗打开管理面板：http://127.0.0.1:63775/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/

部署应用
创建一个sample部署并暴露出8080端口
$ kubectl create deployment hello-minikube --image=k8s.gcr.io/echoserver:1.4 deployment.apps/hello-minikube created $ kubectl expose deployment hello-minikube --type=NodePort --port=8080 service/hello-minikube exposed $ kubectl get services hello-minikube NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE hello-minikube NodePort 10.97.209.29 <none> 8080:31311/TCP 12s
通过minikube启动浏览器去访问服务
$ minikube service hello-minikube |-----------|----------------|-------------|---------------------------| | NAMESPACE | NAME | TARGET PORT | URL | |-----------|----------------|-------------|---------------------------| | default | hello-minikube | 8080 | http://192.168.49.2:31311 | |-----------|----------------|-------------|---------------------------| 🏃 Starting tunnel for service hello-minikube. |-----------|----------------|-------------|------------------------| | NAMESPACE | NAME | TARGET PORT | URL | |-----------|----------------|-------------|------------------------| | default | hello-minikube | | http://127.0.0.1:63931 | |-----------|----------------|-------------|------------------------| 🎉 Opening service default/hello-minikube in default browser... ❗ Because you are using a Docker driver on darwin, the terminal needs to be open to run it.
现在可以访问http://127.0.0.1:63931
CLIENT VALUES: client_address=172.17.0.1 command=GET real path=/ query=nil request_version=1.1 request_uri=http://127.0.0.1:8080/ SERVER VALUES: server_version=nginx: 1.10.0 - lua: 10001 HEADERS RECEIVED: accept=text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9 accept-encoding=gzip, deflate, br accept-language=en-US,en;q=0.9 connection=keep-alive cookie=_ga=GA1.1.596239993.1633627142 host=127.0.0.1:63931 sec-ch-ua="Google Chrome";v="95", "Chromium";v="95", ";Not A Brand";v="99" sec-ch-ua-mobile=?0 sec-ch-ua-platform="macOS" sec-fetch-dest=document sec-fetch-mode=navigate sec-fetch-site=none sec-fetch-user=?1 upgrade-insecure-requests=1 user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36 BODY: -no body in request-我们可以通过kubectl配置端口转发，让外部通过7080端口访问pod的8080端口。
$ kubectl port-forward service/hello-minikube 7080:8080
此时我们可以通过http://127.0.0.1:7080/来访问8080端口服务
LoadBalancer部署$ kubectl create deployment balanced --image=k8s.gcr.io/echoserver:1.4 $ kubectl expose deployment balanced --type=LoadBalancer --port=8080
打开一个新窗口，执行
$ minikube tunnel
使用下面命令获得可路由的ip
$ kubectl get services balanced
现在我们部署的程序就可以在 :8080上访问了

管理集群
暂停kuernetes，但不要影响已经部署的应用
$ minikube pause
恢复kubernetes
$ minikube unpause
终止kubernetes
$ minikube stop
提高默认内存上限，需要重启
$ minikube config set memory 16384罗列已经安装的kubernete服务
$ minikube addons list |-----------------------------|----------|--------------|-----------------------| | ADDON NAME | PROFILE | STATUS | MAINTAINER | |-----------------------------|----------|--------------|-----------------------| | ambassador | minikube | disabled | unknown (third-party) | | auto-pause | minikube | disabled | google | | csi-hostpath-driver | minikube | disabled | kubernetes | | dashboard | minikube | enabled ✅ | kubernetes | | default-storageclass | minikube | enabled ✅ | kubernetes | | efk | minikube | disabled | unknown (third-party) | | freshpod | minikube | disabled | google | | gcp-auth | minikube | disabled | google | | gvisor | minikube | disabled | google | | helm-tiller | minikube | disabled | unknown (third-party) | | ingress | minikube | disabled | unknown (third-party) | | ingress-dns | minikube | disabled | unknown (third-party) | | istio | minikube | disabled | unknown (third-party) | | istio-provisioner | minikube | disabled | unknown (third-party) | | kubevirt | minikube | disabled | unknown (third-party) | | logviewer | minikube | disabled | google | | metallb | minikube | disabled | unknown (third-party) | | metrics-server | minikube | disabled | kubernetes | | nvidia-driver-installer | minikube | disabled | google | | nvidia-gpu-device-plugin | minikube | disabled | unknown (third-party) | | olm | minikube | disabled | unknown (third-party) | | pod-security-policy | minikube | disabled | unknown (third-party) | | portainer | minikube | disabled | portainer.io | | registry | minikube | disabled | google | | registry-aliases | minikube | disabled | unknown (third-party) | | registry-creds | minikube | disabled | unknown (third-party) | | storage-provisioner | minikube | enabled ✅ | kubernetes | | storage-provisioner-gluster | minikube | disabled | unknown (third-party) | | volumesnapshots | minikube | disabled | kubernetes | |-----------------------------|----------|--------------|-----------------------|
创建第二个cluster，运行指定版本的k8s
$ minikube start -p aged --kubernetes-version=v1.16.1
删除所有的sluster
$ minikube delete --all
