microk8s.kubectl get services shows:

(microk8s.kubectl get services显示：)

   NAME               TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
   bb-entrypoint      NodePort    10.152.183.182   <none>        8080:30001/TCP   5m51s
   kubernetes         ClusterIP   10.152.183.1     <none>        443/TCP          35d
   microbot-service   NodePort    10.152.183.80    <none>        80:31223/TCP     19

But, I can't access the bb-entrypoint service via any of following address:

(但是，我无法通过以下任何地址访问bb-entrypoint服务：)

• localhost:30001

The os is mint mate based on ( ubuntu ), and I have disabled ufw .

You have to ensure whether endpoints are created for this service or not by running kubectl get ep In this case i'm seeing endpoints are not created because the pod was having issues in pulling the image from docker and so it i not in ready status

(您必须通过运行kubectl get ep来确保是否为此服务创建了端点。在这种情况下，我看到端点未创建是因为pod在从docker提取映像时遇到问题，因此它没有处于就绪状态)

[root@master tmp]# kubectl get ep

bb-entrypoint                       9m24s

[root@master tmp]# kubectl get po
