Description Stef Walter 2016-03-10 08:29:08 UTC

Description of problem:

The local 127.0.0.1 kubernetes node should register itself in the default install. In the fedora-24 build it no longer does:

Version-Release number of selected component (if applicable):

kubernetes-1.2.0-0.14.alpha6.gitf0cd09a.fc24.x86_64

How reproducible:

Every time


Steps to Reproduce:
1. systemctl start etcd kube-apiserver kube-controller-manager kube-scheduler docker kube-proxy kubelet
2. kubectl get nodes # wait or repeat as needed

Actual results:

No output.

Expected results:

NAME        LABELS                             STATUS
127.0.0.1   kubernetes.io/hostname=127.0.0.1   Ready

Additional info:

This works on fedora-23 with the following kubernetes RPM: kubernetes-1.1.0-0.17.git388061f.fc23.x86_64. In addition the following RPM from fedora-23 updates-testing 1.2.0-0.15.alpha6.gitf0cd09a.fc23

Comment 1 Jan Chaloupka 2016-03-10 09:08:17 UTC

Stef, can you checkout kubernetes-1.2.0-0.15.alpha6.gitf0cd09a.fc23? Running rpms from the build show the expected result.

Comment 2 Stef Walter 2016-03-10 09:20:43 UTC

This problem is happening on Fedora 24. Do you have a Fedora 24 build of that RPM?

Comment 3 Jan Chaloupka 2016-03-10 09:30:54 UTC

Comment 4 Stef Walter 2016-03-10 09:45:53 UTC

The issue remains with that build:

# rpm -q kubernetes
kubernetes-1.2.0-0.14.alpha6.gitf0cd09a.fc24.x86_64
# kubectl get nodes

No output above. All services are running:

Comment 5 Stef Walter 2016-03-10 09:56:18 UTC

I spoke too soon, and didn't get the right build. This build seems to work:

# kubectl get nodes
NAME        LABELS                             STATUS    AGE
127.0.0.1   kubernetes.io/hostname=127.0.0.1   Ready     3s
# rpm -q kubernetes
kubernetes-1.2.0-0.15.alpha6.gitf0cd09a.fc23.x86_64

Comment 6 Jan Chaloupka 2016-03-10 09:58:06 UTC

Thanks for verifying.

Comment 7 Stef Walter 2016-03-10 11:02:36 UTC

Worth noting that this isn't fixed yet in Fedora 24. Although the above build exists. Running 'yum update' on fedora-24 doesn't fix the issue. I think a bodhi update is necessary.

Interesting, though it will take more time to enable updates for f24. Updated.
