Hello team, I have installed kubernetes in centos. After installation when i was checking the version with below command. ``` kubectl version -o json ``` I am getting error below along with version information. ``` { "clientVersion": { "major": "1", "minor": "11", "gitVersion": "v1.11.2", "gitCommit": "bb9ffb1654d4a729bb4cec18ff088eacc153c239", "gitTreeState": "clean", "buildDate": "2018-08-07T23:17:28Z", "goVersion": "go1.10.3", "compiler": "gc", "platform": "linux/amd64" } } ``` The connection to the server localhost:8080 was refused - did you specify the right host or port? Can you please check and advise. Thanks, Hemanth. ---

Hi. Check that the api server is actually running and hasn’t crashed: ```auto docker ps | grep kube-apiserver ``` But the most likely problem and the one that usually gets me is that you don’t have a .kube directory with the right config in it. Try this: ```auto mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config ``` ---

That error should only come up if you have no contexts configured in your client. If you run `kubectl config view` and you get something like this: ```auto $ kubectl config view apiVersion: v1 clusters: [] contexts: [] current-context: "" kind: Config preferences: {} users: [] ``` Then no contexts are configured. ---

This seems like another way to setup the cluster that said on the post ([https://www.techrepublic.com/article/how-to-quickly-install-kubernetes-on-ubuntu/](https://www.techrepublic.com/article/how-to-quickly-install-kubernetes-on-ubuntu/)). Or is it using the same steps? Getting kubectl to run really depends on how you installed it. Basically, if you install and have a proper config file, it should always work. So, either an old file from a previous installation is there or something silly like that (although usually difficult to spot). Also, make sure the commands don’t fail (some on the post pasted that the step to copy the kubectl config failed). That is the way to authorize to the cluster, so it won’t never work if that step doesn’t work 🙂 If I were you, I’d try removing everything from a previous run and starting from scratch and making sure nothing fails. If it does fail, try to fix that instead of continuing with the next steps. And if you can’t fix it, please report back with the steps you did, why it failed (the error) and what you tried and didn’t work. This way it will be easier to solve 🙂 ---

Bom dia Im beggining my studies in Kubernets, follow the tutorial ([Install and Set Up kubectl - Kubernetes](https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-on-linux)) and when type “kubectl cluster-info” I receive the message “To further debug and diagnose cluster problems, use ‘kubectl cluster-info dump’. The connection to the server localhost:8080 was refused - did you specify the right host or port?”. When I run kubectl cluster-info dump receive the message " The connection to the server localhost:8080 was refused - did you specify the right host or port?" The documentation I found tells to search the file admin.conf at folder /etc/kubernets, but when I do it I didn’t find the folder. What can I do? ---

I have currently started working on this as well and I am running into the same brickwall. I am running two nodes, one master and the other host. Both are VMs running CentOS in Oracle Virtual Manager. I got docker installed to the host and kubectl installed to master. I can ssh from master to host and visa-verse. I receive ping replies as well. But cannot telnet into any of the machines from my physical Windows machine. When it comes to “kubectl get nodes” I receive the error: The connection to the server x.x.x.x:6443 was refused - did you specify the right host or port? ~]$ kubectl config view apiVersion: v1 clusters: - cluster: certificate-authority-data: DATA+OMITTED server: [https://x.x.x.x:6443](https://x.x.x.x:6443) name: local contexts: - context: cluster: local user: kube-admin-local name: local current-context: local kind: Config preferences: {} users: - name: kube-admin-local user: client-certificate-data: REDACTED client-key-data: REDACTED I have added the IP address+port to the iptables, tried again. stop the firewalld but still got the same error. ---

Yes I had to be sure I used the “right user”. For me that was a user that had the admin.conf file copied to ~/.kube/config. You can see the difference between the working “pi” users and the “root” user who does not have the config file: ```auto pi@node0:~ $ sudo kubectl get pods --all-namespaces The connection to the server localhost:8080 was refused - did you specify the right host or port? pi@node0:~ $ kubectl get pods --all-namespaces NAMESPACE NAME READY STATUS RESTARTS AGE kube-system coredns-f9fd979d6-jjsjr 1/1 Running 0 11h kube-system coredns-f9fd979d6-xl5f2 1/1 Running 0 11h kube-system etcd-node0 1/1 Running 0 11h kube-system kube-apiserver-node0 1/1 Running 0 11h kube-system kube-controller-manager-node0 1/1 Running 0 11h kube-system kube-flannel-ds-arm-4zq4g 1/1 Running 0 11h kube-system kube-flannel-ds-arm-dcprj 1/1 Running 0 11h kube-system kube-flannel-ds-arm-fwzkl 1/1 Running 0 11h kube-system kube-flannel-ds-arm-q8t5k 1/1 Running 0 11h kube-system kube-proxy-dlhc7 1/1 Running 0 11h kube-system kube-proxy-glh92 1/1 Running 0 11h kube-system kube-proxy-jh26p 1/1 Running 0 11h kube-system kube-proxy-qflcw 1/1 Running 0 11h kube-system kube-scheduler-node0 1/1 Running 0 11h ``` ---
