请问 node port 30001 -> 80 和端口转发的 80 -> 80 关系是什么呢， 好像没看到 30001 端口哪里有用到。

kubectl apply -f test的时候，报这个错误是什么意思，该怎么解决 service/account-service unchanged service/app-service unchanged service/bot-service unchanged service/company-service unchanged service/email-service unchanged service/faraday-service unchanged service/myaccount-service unchanged service/mysql-svc unchanged service/whoami-service unchanged service/www-service unchanged [unable to recognize "test\\account-svc.yaml": no matches for kind "Deployment" in version "extensions/v1beta1", unable to recognize "test\\app-spa.yaml": no matches for kind "Deployment" in version "extensions/v1beta1", unable to recognize "test\\bot-svc.yaml": no matches for kind "Deployment" in version "extensions/v1beta1", unable to recognize "test\\company-svc.yaml": no matches for kind "Deployment" in version "extensions/v1beta1", unable to recognize "test\\email-svc.yaml": no matches for kind "Deployment" in version "extensions/v1beta1", unable to recognize "test\\faraday-svc.yaml": no matches for kind "Deployment" in version "extensions/v1beta1", unable to recognize "test\\myaccount-spa.yaml": no matches for kind "Deployment" in version "extensions/v1beta1", unable to recognize "test\\whoami-svc.yaml": no matches for kind "Deployment" in version "extensions/v1beta1", unable to recognize "test\\www-web.yaml": no matches for kind "Deployment" in version "extensions/v1beta1"] Error from server (Invalid): error when creating "test\\mysql-svc.yaml": Endpoints "mysql-svc" is invalid: subsets[0].addresses[0].ip: Invalid value: "127.0.0.1": may not be in the loopback range (127.0.0.0/8)

波波老师，您好，访问http://www.staffjoy-v2.local/时报Caused by: org.apache.http.conn.HttpHostConnectException: Connect to www-service:80 [www-service/10.108.178.127] failed: Connection refused (Connection refused) at org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:159) at org.apache.http.impl.conn.PoolingHttpClientConnectionManager.connect(PoolingHttpClientConnectionManager.java:373) at org.apache.http.impl.execchain.MainClientExec.establishRoute(MainClientExec.java:394) at org.apache.http.impl.execchain.MainClientExec.execute(MainClientExec.java:237) at org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:185) www-service服务也是正常启动，是否跟配置有关呢？谢谢 NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE account-service ClusterIP 10.97.249.236 <none> 80/TCP 2d2h app-service ClusterIP 10.111.60.205 <none> 80/TCP 2d2h bot-service ClusterIP 10.107.240.129 <none> 80/TCP 2d2h company-service ClusterIP 10.100.242.5 <none> 80/TCP 2d2h email-service ClusterIP 10.101.169.176 <none> 80/TCP 2d2h faraday-service NodePort 10.96.194.213 <none> 80:30001/TCP 2d2h kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 2d2h myaccount-service ClusterIP 10.101.67.246 <none> 80/TCP 2d2h mysql-svc ClusterIP 10.106.215.144 <none> 3306/TCP 2d2h whoami-service ClusterIP 10.100.138.182 <none> 80/TCP 2d2h www-service ClusterIP 10.108.178.127 <none> 80/TCP 2d2h

老师有个问题请教一下： 这种springBoot + k8s 的方式开发微服务，多服务之间调用比如 A调用B B调用C 等 本地开发的时候 如何调试啊？ 传统的springCloud系列，我们可以在本地启注册中心/网关等，然后自己注册到本机去调试 这种springBoot + k8s 如何调试，本地也访问不了k8s内部的吧 单独的某一个服务调试还好，毕竟只是一个单点项目，自己运行起来就好了，多个服务联调的呢 老师有没有什么好的方案啊

波波老师你好！ 我用mac docker-desktop部署了微服务后， kubectl log -f {podname} 为什么有些pod的日志只显示了一点点。 应用功能是没有问题的。

[chaozhang@fedora test]$ sudo kubectl port-forward faraday-svc-deployment-597569cc98-t7pmr 80:80 [sudo] password for chaozhang: The connection to the server localhost:8080 was refused - did you specify the right host or port? 不断遇到问题，哈哈

波波老师，我部署以后收不到邮件，该怎么调整

请问一下老师，我的环境是在ubuntu主机上开了三台centos虚拟机(master,node01,node02)。但是运行kubectl port-forward faraday-svc-deployment-b669bd748-f9zzb 80:80后，switchhost是在ubuntu主机上配置域名？还是在虚拟机上配置127.0.0.1 staffjoy-local ...？。并且我在ubuntu/虚拟机上用curl 127.0.0.1/curl {虚拟机物理地址}都显示拒绝访问。请问一下波波老师这个是什么问题呀。
