the same for the first time when i ran v0.20.1 (the published one)
here is the installation log on my core i5-5200U ubuntu 14.04 3.16 kernel this is that console says
See my comment on
I think is probably right. There's a 0.20.2 brewing already (and we should have it out later today), so hang tight.
I just tried this also with Release 0.20.2 Candidate on Ubuntu 14.04 with VirtualBox, Vagrant and I am seeing:
- Is there someone on your team that could take a look?
Honestly no, everyone is busy, and working on either cluster or network related issue. But I talked to briefly, he kindly agree to take a look. The cloud provider here is Vagrant, if you could reproduce the issue, that would be huge help. Feel free to re-assign it to me if you are blocked. Thanks!
cc/ since he looked into vagrant issue lately. cc/ on Vagrant.

+1, 0.20.2 still has this issue
+1
The fix for this issue is this PR:
Assigning issue to me since I am focused today on closing out remaining Vagrant setup issues.
Sigh, I'm sorry. So busy working through unassigned PRs I forgot to work through my own queue.
I was running into the same issue and cherry picked your changes in , but still have the same issue. Prior to those changes the kubelet never started on the master. With the changes it does start, but I still get: It looks like also needed before vagrant works correctly.
Yep, I picked and then merged and it started to work again... just my 2 cents
this error is gone in 0.21.0 rc ()

I'm running into a similar issue with a Kubernetes cluster on AWS. I set it up last week and now can't connect to the master node: oamasood kubectl cluster-info error: couldn't read version from server: Get https://11.11.111.111/api: dial tcp 11.11.111.111:443: connection refused Any help would be appreciated.
I find that if you wait for the master and minion to calm down on activity after a bit (~5 minutes) the kubectl commands work, however the problem is I don't see any nodes running.

I have re-installed virtual box, made sure my .kube directory is clean and I am now pulling just the stock vagrant box cube fedora 21 and kubernetes 1.0.4 release. I do not see any docker processes running on my minion. Other than that it seems that the cluster is running: $ get cs NAME STATUS MESSAGE ERROR controller-manager Healthy ok nil scheduler Healthy ok nil etcd-0 Healthy {"health": "true"} nil $ cluster-info Kubernetes master is running at https://10.245.1.2 KubeDNS is running at https://10.245.1.2/api/v1/proxy/namespaces/kube-system/services/kube-dns KubeUI is running at https://10.245.1.2/api/v1/proxy/namespaces/kube-system/services/kube-ui yggdrasil:kubernetes jonathantronson$ vagrant ssh master Last login: Wed Sep 16 23:49:51 2015 from 10.0.2.2 [vagrant ~]$ sudo docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES "/bin/sh -c '/usr/loc" 50 minutes ago Up 50 minutes k8skube-apiserver.2abef58bkube-apiserver-kubernetes-masterkube-system496e220b4704d4b390883b4b90aa66354e41e61f "/bin/sh -c '/usr/loc" 50 minutes ago Up 50 minutes k8setcd-container.fa2ab1d9etcd-server-kubernetes-masterkube-system6ef1b07678064a7edcdbec6f0570e91759d753f9 "/bin/sh -c '/usr/loc" 53 minutes ago Up 53 minutes k8skube-scheduler.ea78c200kube-scheduler-kubernetes-masterkube-system3d1ced0542467b566546021cb74d9bdf9550be6a "/bin/sh -c '/usr/loc" 53 minutes ago Up 53 minutes k8skube-controller-manager.fd0f0b82kube-controller-manager-kubernetes-masterkube-system2f59d05ecb2212d0379dc35dbe40d5216292ac06 "/pause" 54 minutes ago Up 54 minutes k8sPOD.

when I rerun the cluster/kube-, the error still exist, and can't get nodes/services etc status. The first time, it works. weird.
can u help to take a look this issues? thanks
- can you open a new issue and describe what host environment you are using? Are you testing from master or a branch? cc me on the issue.
I used released version 1.1.7. btw, I tried several times. even at the last step failed. I can run get pods/services etcs. seems during verify stage. it will search local kubectl files? I am not sure. as on my Mac , there have some mismatch version kubectl file.
I experience the very same issue on AWS and, usually, I can't connect to my cluster anymore the day after I had set it up - which is a huge blocker. Here's the output from :
I expreience the same issue on Ubuntu.
The issue disappeared for me with the following version:
I encounter the same problem,can you give me a detail configuration of kuberenetes?
