Trying to run container in microk8s.

According to https://docs.docker.com/get-started/part3/ , after deploy the service.

microk8s.kubectl get services shows:

   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:

  • localhost:30001
  • 10.152.183.182:8080

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

Any idea?

  • You need to provide a [mcve] for this to be debuggable: where are you making this call from, what specific error are you getting, and what YAML files are you using to define the deployment and service objects? This could be caused by making the HTTP call from the wrong place, or the pod and service labels not matching up, or the pod just not starting up, or... – David Maze Dec 01 '19 at 19:32

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

[root@master tmp]# kubectl get ep
NAME            ENDPOINTS           AGE
bb-entrypoint                       9m24s

[root@master tmp]# kubectl get po
NAME                         READY   STATUS                       RESTARTS   AGE
bb-demo-7ffb568776-q6xs2     0/1     ImagePullBackOff             0          9m55s

  • Thanks, I found the solution here: https://stackoverflow.com/questions/58631155/how-to-fix-failed-to-pull-image-on-microk8s . After login to docker, and push the image to docker.io, then pull from remote instead would fix it. – Eric Dec 01 '19 at 17:27
