Question

所以我一直在玩Minkube。

我设法部署了一个简单的python flask容器：

PS C:\Users\Will> kubectl run test-flask-deploy --image 
192.168.1.201:5000/test_flask:1 
deployment "test-flask-deploy" created

我还设法将部署公开为服务：

PS C:\Users\Will> kubectl expose deployment/test-flask-deploy --
type="NodePort" --port 8080
service "test-flask-deploy" exposed

在仪表板中，我可以看到该服务具有群集IP： 10.0.0.132。

我访问192.168.xxx.xxx地址的仪表板，所以我希望我可以在该外部IP上公开该服务。

知道我怎么回事吗？

一个单独且稍微不那么重要的问题：我已经让minikube与我的网络上的docker注册表进行了对话。如果我部署了一个映像（尚未将其局部拉到minikube上），则部署失败，但是当我在本地minikube上运行docker pull命令时，部署会成功。因此minikube能够提取docker镜像，但是当我部署可通过注册表访问但尚未在本地拉出的图像时，它会失败。有什么想法吗？

Answer 1

首先，检查分配给您的服务的节点端口：

setonItemclick

现在，您应该可以在$ kubectl get svc test-flask-deploy NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE test-flask-deploy 10.0.0.76 <nodes> 8080:30341/TCP 4m或192.168.xxxx:30341上访问它。

Kubernetes minikube，无法在公共IP范围
