user@master:~$ kubectl get deployments
error: the server doesn't have a resource type "deployments"

kubernetes version: 1.12

kubectl version: 1.13

kubectl api-versions:

apiregistration.k8s.io/v1

apiregistration.k8s.io/v1beta1

Thanks for your helps.

-----------Edit 1-----------

Hello @EduardoBaitello, Thank you for quicly reply. The problem is not related to permission.

user@master:~$ kubectl auth can-i get deployments Warning: the server doesn't have a resource type 'deployments' yes user@master:~$ kubectl auth can-i get deployment Warning: the server doesn't have a resource type 'deployment' yes user@master:~$ kubectl auth can-i get namespaces yes user@master:~$ kubectl auth can-i get pods yes

So I think this is not a duplicated question.

user@master:~$ kubectl get po --namespace=kube-system NAME READY STATUS RESTARTS AGE calico-kube-controllers-7c6b876df8-nk7nm 1/1 Running 2 118d calico-node-8lt9f 1/1 Running 3 118d calico-node-d9r9l 1/1 Running 2 118d calico-node-ffqlj 1/1 Running 2 118d dns-autoscaler-57ff59dd4c-c9tjv 1/1 Running 2 118d kube-apiserver-node1 1/1 Running 3 118d kube-controller-manager-node1 1/1 Running 6 118d kube-dns-84467597f5-hf2fn 3/3 Running 6 118d kube-dns-84467597f5-sttgx 3/3 Running 9 118d kube-proxy-node1 1/1 Running 3 118d kube-proxy-node2 1/1 Running 2 118d kube-proxy-node3 1/1 Running 2 118d kube-scheduler-node1 1/1 Running 6 118d kubernetes-dashboard-5db4d9f45f-gkl6w 1/1 Running 3 118d nginx-proxy-node2 1/1 Running 2 118d nginx-proxy-node3 1/1 Running 2 118d tiller-deploy-6f6fd74b68-27fqc 1/1 Running 0 16d

Answer 1

I was experiencing exactly the same behavior as in "Edit 1" above with Kubernetes 1.13.5 (client and server). Removing the ~/.kube/http-cache directory on the client worked for me.

I suspect this is because of Kubectl binary version. I noticed your kubectl version(1.13) is higher than the Kubernetes version(1.12).

can you try downgrading your kubectl version to 1.12 or lower?
