【问题描述】：
我是 Kubernetes 的新手。
我无法使用 kubectl 获取部署，但我可以在 kubernetes 仪表板上查看所有部署。我该如何解决这个问题？
user@master:~$ kubectl get deployments
error: the server doesn't have a resource type "deployments"
kubernetes 版本： 1.12
kubectl 版本： 1.13
kubectl api 版本：
apiregistration.k8s.io/v1
apiregistration.k8s.io/v1beta1
v1
api 资源：
user@master:~$ kubectl api-resources

您好@EduardoBaitello，感谢您的快速回复。问题与权限无关。
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
所以我认为这不是一个重复的问题。

看起来像duplicated question。也许您的问题是缺少获取 deployment api-resource 的 RBAC 权限。你能从 kube-system 命名空间检查 pod 吗？ (
kubectl get po --namespace=kube-system)。崩溃的 etcd pod 可能会导致一些 api-resources 丢失...另外，请检查 kube-apiserver pod 的日志。 -
你能分享输出吗：
kubectl get deployments -v10？
