Question

尝试在带有nginx图像的minikube中运行简单服务

我使用波纹管命令运行了部署和服务

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

可以正确创建我的服务，但是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

有关我提供的信息，介绍了服务和部署

Answer 1

在Kubernetes之外无法使用类型为ClusterIP的服务。您需要使用服务类型LoadBalancer或NodePort。

请阅读：

使用minikube创建服务
