"No resources found" 来自 kubectl 获取远程集群

Question

我已经为涉及 Docker Mac 附带的本地 Kubernetes 和使用 Minikube 的远程集群的多集群设置配置了 kubectl。当我将上下文切换到我的远程集群时，kubectl 找不到任何资源，如 pods 或服务。我在哪里可以查看日志以了解更多信息？如果我运行 kubectl 在实际的远程机器上，我确实看到了资源。

当我执行 kubectl version 我得到这个：

Client Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.11", GitCommit:"637c7e288581ee40ab4ca210618a89a555b6e7e9", GitTreeState:"clean", BuildDate:"2018-11-26T14:38:32Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.3", GitCommit:"721bfa751924da8d1680787490c54b9179b1fed0", GitTreeState:"clean", BuildDate:"2019-02-01T20:00:57Z", GoVersion:"go1.11.5", Compiler:"gc", Platform:"linux/amd64"}

kubectl get componentstatus returns:

NAME                 STATUS    MESSAGE              ERROR
scheduler            Healthy   ok                   
controller-manager   Healthy   ok                   
etcd-0               Healthy   {"health": "true"}

kubectl cluster-info returns:

Kubernetes master is running at https://remote-cluster-ip:8443
KubeDNS is running at https://remote-cluster-ip:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

执行 kubectl cluster-info dump 会产生大量输出。

我按照这些步骤让 Minikube 工作并成功部署了一个示例应用程序。 https://kubernetes.io/docs/setup/minikube/

我按照以下步骤进行多集群配置： https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/

我将所有 crt 和密钥文件从 .minikube 复制到我的本地计算机以用于配置。这是我编辑过的配置：

apiVersion: v1
clusters:
- cluster:
    insecure-skip-tls-verify: true
    server: https://localhost:6443
  name: docker-for-desktop-cluster
- cluster:
    insecure-skip-tls-verify: true
    server: https://remote-cluster-ip:8443
  name: remote-cluster
contexts:
- context:
    cluster: docker-for-desktop-cluster
    user: docker-for-desktop
  name: docker-for-desktop
- context:
    cluster: remote-cluster
    namespace: remote-cluster
    user: minikube
  name: remote-cluster
current-context: remote-cluster
kind: Config
preferences: {}
users:
- name: docker-for-desktop
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED
- name: minikube
  user:
    client-certificate: /path/to/local/client.crt
    client-key: /path/to/local/client.key

运行 kubectl get pods --all-namespaces 检查您是否可以在所有命名空间中看到 pods。如果您看到 pods 是运行，那么您必须为当前上下文设置默认名称空间，即

kubectl config set-context <remote-context-name> --namespace=default
