When I try to run kubectl command through sshpass,it failed with Unable to connect to the server

Question

I used such command:

sshpass -p password ssh root@x.x.x.x 'date;kubectl get pod;date'

I got:

Wed Sep 20 14:39:19 CST 2017
Unable to connect to the server: EOF
Wed Sep 20 14:39:20 CST 2017

How to fix this issue?

All kubectl commands work well on target system. Command:

sshpass -p password ssh root@x.x.x.x 'kubectl'

also work well:

 mynode /etc » sshpass -p password ssh -o StrictHostKeyChecking=no root@x.x.x.x "kubectl"                                                        
kubectl controls the Kubernetes cluster manager. 

Find more information at https://github.com/kubernetes/kubernetes.

  create         Create a resource by filename or stdin
  expose         Take a replication controller, service, deployment or pod and expose it as a new Kubernetes Service
  run            Run a particular image on the cluster
  set            Set specific features on objects

Basic Commands (Intermediate):
  get            Display one or many resources
  explain        Documentation of resources
  edit           Edit a resource on the server
  delete         Delete resources by filenames, stdin, resources and names, or by resources and label selector
...

see you can pass the k8s configuration file and test it . kubectl --kubeconfig=path to kube config — sfgroups

can you try run something like this?

ssh master-01 -x 'kubectl --kubeconfig=/root/.kube/config get nodes'

in your case like this:

 sshpass -p password  ssh master-01 -x 'kubectl --kubeconfig=/root/.kube/config get nodes'
