WSL2环境下Minikube NodePort服务curl超时问题求助

环境 #

• WSL2
• minikube
• Windows 11
• Calico插件
• Docker-Desktop

问题 #

执行curl http://$(minikube ip):32000时出现连接超时，已查阅Stack Overflow相关问题但均不适用。

操作步骤 #

1. 创建Nginx部署及对应的Service：

$ k create deploy nginxsvc --image=nginx --replicas=3
$ k expose deploy nginxsvc --port=80

2. 编辑该Service，将类型修改为NodePort。

相关命令输出 #

k get svc输出 #

$ k get svc
NAME               TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
kubernetes         ClusterIP   10.96.0.1       <none>        443/TCP        18d
nginxsvc           NodePort    10.103.11.225   <none>        80:32000/TCP   19m
regular-encourager NodePort    10.102.236.129  <none>        8080:32058/TCP 15d

curl命令执行结果 #

$ curl http://$(minikube ip):32000
curl: (28) Failed to connect to 192.168.49.2 port 32000: Connection timed out

k describe svc nginxsvc输出 #
