无法使用 minikube 连接到 NodePort URL

Question

我只是在尝试一个非常简单的 NodePort 示例，在 Apple M1 机器上使用 minikube。我基本上是通过 minikube 创建一个单节点 k8s 集群，然后创建一个 1-pod 部署和 NodePort 服务。 NodePort URL 不断为我加载。以下是我使用的命令。

$ minikube start
????  minikube v1.25.2 on Darwin 12.4 (arm64)
✨  Automatically selected the docker driver
????  Starting control plane node minikube in cluster minikube
????  Pulling base image ...

????  Enabled addons: storage-provisioner, default-storageclass
????  Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default


$ kubectl create deployment nginx-deployment --image=nginxdemos/hello
deployment.apps/nginx-deployment created


$ kubectl expose deployment nginx-deployment --type=NodePort --port=80
service/nginx-deployment exposed


$ minikube service nginx-deployment
????  Starting tunnel for service nginx-deployment.
????  Opening service default/nginx-deployment in default browser...
❗  Because you are using a Docker driver on darwin, the terminal needs to be open to run it.

=> This opens the URL in the browser (e.g. http://192.168.49.2:32739/), but it keeps loading forever

当我 SSH 进入节点时，我可以毫无问题地 curl pod IP。

$ minikube ssh
Last login: Thu May 26 10:09:35 2022 from 192.168.49.1

# This is the IP of the running pod
docker@minikube:~$ curl -sI 172.17.0.3 | grep HTTP
HTTP/1.1 200 OK

我还看到服务绑定到 pod：

$ kubectl describe service nginx-deployment

Name:                     nginx-deployment
Namespace:                default
Labels:                   app=nginx-deployment
Annotations:              <none>
Selector:                 app=nginx-deployment
Type:                     NodePort
IP Family Policy:         SingleStack
IP Families:              IPv4
IP:                       10.109.174.147
IPs:                      10.109.174.147
Port:                     <unset>  80/TCP
TargetPort:               80/TCP
NodePort:                 <unset>  32739/TCP
Endpoints:                172.17.0.3:80
Session Affinity:         None
External Traffic Policy:  Cluster
Events:                   <none>

我做错了什么？

Answer 1

我通过改用 Docker Desktop kubernetes 解决了这个问题。好像 minikube 不能很好地与 Apple M1 配合使用。
