尝试使用nginx图像在minikube中运行简单服务
我使用bellow命令运行部署和服务
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
是否正确创建了我的服务,但我无法通过端口访问端点
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
felipeflores@GMEPN004052:~$ curl 10.108.164.133
curl: (7) Failed to connect to 10.108.164.133 port 80

不能从Kubernetes外部获得ClusterIP类型的服务。您需要使用服务类型LoadBalancer或NodePort。
