使用 minikube 创建服务

Question

尝试运行 minikube 中带有 nginx 镜像的简单服务

我运行使用以下命令进行了部署和服务

felipeflores@GMEPN004052:~$ kubectl run meu-nginx --image nginx --port 80
kubectl run --generator=deployment/apps.v1 is DEPRECATED and will be removed in a future version. Use kubectl run --generator=run-pod/v1 or kubectl create instead.
deployment.apps/meu-nginx created
felipeflores@GMEPN004052:~$ kubectl expose deployment meu-nginx
service/meu-nginx exposed

已正确创建我的服务，但我无法使用端口

访问端点

felipeflores@GMEPN004052:~$ kubectl get service
NAME                TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
kubernetes          ClusterIP   10.96.0.1        <none>        443/TCP        55d
meu-nginx           ClusterIP   10.108.164.133   <none>        80/TCP         20m

但是

felipeflores@GMEPN004052:~$ curl 10.108.164.133
curl: (7) Failed to connect to 10.108.164.133 port 80

ClusterIP 类型的服务不可从 Kubernetes 外部使用。您需要使用服务类型 LoadBalancer 或 NodePort。
